Abstract

A communication terminal apparatus connected to a communication network through a data channel for transfer of such data as line transaction data or packet transaction data and through a signal channel for control of a call to a communication destination party. Communication terminal apparatuses including such a communication terminal apparatus are connected to the communication network and subscriber numbers are usually previously designated, as identification data, to all subscribers of the communication network and as necessary, address data (referred to as subaddresses) arbitrarilyset among some of these subscribers are attached to the some subscriber numbers. These subscriber numbers and subaddresses are transmitted and received through the signal channel separately from transaction data transmitted and recieved through the data channel. The present apparatus fundamentally performs predetermined control operations which includes the following a) to c), depending on whether or not the then received subscriber number (subaddress, if necessary) coincides with one of the previously registered subscriber numbers (subaddresses):
a) Grants or rejects the reception of the associated transaction data.
b) Automatically transmits the assocaited transaction data to another communication terminal.
c) Displays such auxiliary data such as previously registered subscriber's name corresponding to the subscriber number.

TITLE OF TH~ ~N~ENTION
Co~m~nica~ion terminal apparatus BACKG~OUND O~ THE INVENTION
1. ~ield of the Invention ~ 'he present i~vention relates to communication termirl~ls which are connected to a communication network throu~h ~ da~a channel for transfer of such data as line transaction data or packet transaction data and throuqh a slgna] channel for control of a ~all to a communi~ation destirlation p~rty, and ~ore particularly, to a commurliçAtion termin~l apparatus which can realize effective communication processing o~ the basis of proper identifcation of subscriber numbers or subaddresses received or transmitted thro~gh the si~nal channel as i~lentification da~

2. Description of the Related Art ~ n prior art communication networ~s, a data ch~nnel for ~ransfer of transaction data is separ~ted from ~
sign~l channel for tr~ns~er of control data as mentioned above so th~t, for example, the contr~l data can always be trsnsnlitted through the signal channel independently of voice or pic~ure dat~ as the transa~tion data or con~rol of a plurality o~ such data ~hann~ls can be established throuc~h the single signal ch~nne~, whereby different sorts of se~vices including t~lephone, telex and facsimile can be efficientLy and integrally realized. One of these pr-ior art comm~nication networks is, as well know~,an IS~N
(Integr~ed Services ~i~ital ~etwo~k)~

In the ISDN, the above data channel is referred to a5 the B channel and the a~ove signal ~hannel is referred ~o a~ the D channel. Thro~gh ~he D channel o the signal ohannel, i~ particular, identific~tion d~ta on caller communica~on terminals ca~ also be transmitted as con~rol data. Accordingly, a ~ommunication termi~al to be called can know, on the basis of the identific~tion da~a of ~he caller- communication terminal received th~ough the D
ch~n~el, one of the communic~tion terminals which issu~d the transmissio~ data ~voice or picture da~) of th~ B
chann~l. The identifi~ation d~ta includes subscriber numbers previously designated to subscribers of the communication netwo~k and subaddresses arbitrarily set among some of the subscribers as additional data to the subscriber numbers. The subaddres~es, which are attached to some of the subscriber num~ers as necessary, are used, for exa~ple, when it is desired to specify one of a group of ~erminals (user in-home facili~ies) to which a common subscriber number is designated.
Such IS~N ~an ind~ed re~lize such various sorts of services as mentioned abo~e integrally and efficiently and also can allow the signal-r~ceived (receiver) communication termin~ls to recognize the caller communication te~minal on the basis of the identification data of an incomin~ signal received from the D ch~nnel.
In the prior art communi~a~ion terminal appara~us ~onnected to the ISDN, however, the identifi~ation data has been used onl~ for the purpose of thç reco~nization or .
.

ident~fi~tion of the caller termi~al and processing, control and so on concerninc3 the actual communic~tion have been separ~tely carried out through operator's cont~ol panel. As a result, the ISDN has not fully been utili.~ed in overall communication ~ficiency.
~ `or example, the following utilization forms (a) to (e) are highly import~nt for the purpose of reali~ing impro~ed user interface as a co~m~nic~tion ~erminal apparcltus and thus realizing a hi~h communication eficien~ of the overall commu~i~ation ne~work. However, it has ~een impossible for the existin~ communication t~rmir~al appara~us, even how it is connected to the ISDN, to re~ e these utilie~tion forms.
(a) Transaction data sent from the specific ~ommunication te~rmirlal can be automati~ally transmitted to ~nother speci~ic communication terminal~
(b) qhe operator at the communication terminal to be c~lled can immediately know the c~ller subscriber (caller commurlication termina~).
(c) The specific communication terminal can be autom~ltically set in its spec~fic mode independently of the communication protocol~
~d) When thç ~ommuni~a~ion terminal to be called is in it~
commu~lication disable state and l~ter the state is removed, ~ message indicative of removal of such state i5 automati~ally sent to the caller communication termina~.
(e) ArbitrAry incoming-signal reception conditions are set wi.~h use ~f the above identification data and arbi~rary incomin~-signal reception control is carried out on the balsis of the satis~action o~ unsatisfaction of the conditions.

.
~ ssume now that a~other communication terminal (not shown facsimile ma~hine) connected to the ISDN issued a signa~ to the first embodiment appar~tus shown in Fig. 1.
Then t.he caller communica~ion terminal first sends to the ISDN cl signal for calling the irst embodim~nt apparatus ~which signal is referred to as the calling signal). The calling signal usually contains a dat~ indic~ive of a caller subsc~ib~r number previously desi~nated to t~e signal-originator (caller) communication terminal.
q'he callin~ signa~ thus sent to ~he ISDN from the caller communica~ion termin~l is received as an in~ominq call signal at the network controller 11 of tho embodiment ~pparatus through the ~SDN line (D channel).
l~he first embodiment apparatus, when receiving the incoming call signal at the network controller 11 and recogr,izing the presence of ~he incoming signal at ~he centrzl controller 1 (s~ep 101 in Fi~. 2), starts its proces.sing in the following manner.
~1) The central controller 1, when recognizing the preser,ce of the incoming signal on the basis of no~ification from the net~ork con~roller 11, ~heck~
through the network con~roller 11 whether or not the incomi~g signal contain.c the c~ller subscriber nu~ber of the calller communication terminal (step 102 in Fig. ~).
(2) ~hen h~ving determin~d th2t the caller subscriber number is not in~luded in ~he incomin~ signal, the central contrclller 1 controls the e~bodiment appara~us to perfo~m its u~;ual incoming-call answering ope~ation. That is, in -l5-this case, a picture d~ta sent together with the incoming signal is suitably~dem~du~ated through the communication controller 12, transmitted to the picture buffer processor 37 an~ then recorded on a recordin~ paper through the recorder 35 (step tO3 in Fig. 2).
(3) ~Yhen determining (in step 10~ in Fig. 2) that the caller subscriber number is included in ~he incoming si~nal, the central controller 1 causes th~ reqister contrc,lle~ 4~ to set (store~ the included caller s~bsc~iber num~er in the ID regi~ter 42 (step 1~4 in Fiq.
2). At this time, if another c~lle~ subscrlber number (corresponding to the previous incoming signal) is alre~dy se~ in the ID regi~ter 42, then the previous caller subscribe~ n~mber is repl~ced by the n~w one for its r~newal, unless the I~ register 42 is cleared each time the pro~essing is completed.
~ 4) The central controller 1 ne~t checks whether or not the c~ller subscriber number for specifying the caller is previc~usly regictered in the caller ~D memory 44 (step 105 in Fi~l. 2).
(5) ~rhe controller 1, when determinins that ~he caller subsc~iber number is not registered, ~ontrol ~he embodi.ment apparatus to perform i~ ~su~l incomlng-call answering operation as in (~). the above p~c~essing Thereby, a picture dat~ being sent as associ~ted with the incomi.n~ call si~nal is suitably demodulated through the commw~ication controller 12, transmltted to the picture buf~e~ processor 37 and then rec~rded on ~ recording paper -l6-through the recorder 35, as has been explained abo~e.
(~) rhe eontroller 1, when deter~ing tha~ the caller subscriber number included in the incoming signal is reqis~ered in the caller I~ ~emory 44 (step 105 in Fig.
2), reads out associated ~ne o~ ~he caller s~bscriber nu~bers f~om the caller ID memory 44 through the memory controller 46 and compares the read subscriber number with the s~ ccriber number set in the ID regis~er 42 (step 106 in Fig. 2).
(7) When determining to be a none-coincidence in subsc~iber number as the comparison result ~step 107 in Fig. 2), the cent~al controller 1 repeats the above processin~ (6)(step 106 in Fi~. 2) so long ~s other caller subscriber numbers are registered in the caller I~ memory 44 (st:ep 108 in Fig. 2). When the central controlle~ 1 dete~mines that any one of the subscri~er numbers registered in the caller ~D memory 44 does not coincide with the subscriber number set in the I~ re~ister 4~, ~he controller 1 controls the embodiment apparatus to perform i~s usual in~oming-call ans~ering operation as in the above processing (2) (step 103 in Fig~ 2).
(a) When de~ermlning through the compa~ison (step 106 in Fig. 2) to be a su~s~ribe~ num~er coinciden~e ~tep 107 in Fig. "), the central controller 1 answers to the incoming call ~ind then controls tc s~ore in the pict~re memory 2 the plcture data re~eived through the network controller 11 and the communic~tion controller 12 (step 109 in Fig.
2) .

~ g) When the input picture data h~s been stored in the pi~tuAre memory 2 in-this wa~, or in othe~ words, when the above coincided subscriA~e~ number hac alread~ been registered in the caller I~ memory 44, the central controller 1 next re~ds out from the receiver ID memory 45 one of recei~er subscriber numbers registered in the receiver ID memory 45 which is assoc~ated with the ~oincided caller subscriber number through the memory controller 46, and performs the c~lling operation of the read receiver s~bscriber number (desired s~bscriber number to be transf~rred) throu~h the communicatio~ controller 1 and the ne~work controller 11 (step 11~ in Fig. 2).
(1~) When the callinq op~ration causes the present apparatus to be put in a data ~ransaction en~Able st~te wi~h the party communi~a~ion terminal (the faccimile machine to be called), the cent~al controller 1 fin311y transfers the pickure data stored in the picture memory 2 to the party co~mu~ication t~rminal newly put in the communication state (step 111 in Fig. 2). Of course, such data transfer is ca~ried out also und~r the communication contraller 1~ and the network con~roller tl making up the communication part 10.
Through the above processings of the apparatus of the first embodimen~, the prese~t embodimen~ app~ratu~ c~n also ~e used as a relay terminal to realiAze picture data automatic transfeAr between the specific communic~tion terminalsA In other ~ords, even if the operator of the present app~ratus is absent, favorable pictu~e data transf~r can be effected ~etween the communication terminals (facsimile ma~hines) each h~ving a registered number, so lon~ as the uni~e numbers are previously registered in the c211er and receiver ID memories 44 and 45, thus reali~ing the flexibls utilization o~ these co~munication terminals.
In the fi~st embodiment appar~us, the above calling processing (9) and data tr~nsfer processin~ ) may be parallelly car~ied out utilizing the idle data ~hannel (B
~hannel) whil~ the above pi~ture data i~ stored in the picture memory 2 durlng ~eception of the picture da~a, or alternatively may ~e separately s~arted after the comp~etion of c~mmunication with the calle~ party (caller communication terminal).
ln the foregoing embodiment, in the C~SB wh~re a plurality of subscriber numbers a~e registere~ in each of the caller and reciever ID memo~ies 44 and 45, ~hese numbe~s h~ve besn read therein on on~-ater-one b~sis for comparison through the p~oc~ssings of steps 106, 107 and 108 o~. Fig. 2. HoweYer, such a readin~-in control system of these subscriber numbers under the memor~ controller 4~
i5 no~ ~estricted to the above specific one and may be arbitrarily carried out so long a~ all the subscri~er numbers registered can be compa~ed or collated~ That is,this comparison or collati~n proce.~sing, of course, may be carried out as by reading all the re~istered -cubscriber number-s at the same ~ime colle~tively in a register (not shown) incorporated in the central cont~oller 1.

-Eurther, although onl~ subs~riber num~ers ha~e ~een used as identific~tion data IDs respectively uniquel~
specifying commu~ication ~erminals in the above embodiment. since a subaddress ~ogether wi~h a c~lle~
subscriber number is also sometimes included in an incoming signal in s~h a comm~nication network, this subaddress may a1so be positively utilized as an ide~tificatio~ data ~D specifyin~ one of the communication termirlals. In this cas~, this subaddress of the incoming signal is also temporarily sto~ed to~ether with the su~s~riber number of the incoming ~ignal in the I~
re!gister 42 and also arbitrary subaddresses a~e previously regist.ered toge~her with the associated subscriber numbers specifyinq caller co~munica~ion terminals in the caller ID
memor~ 44. And when the present embodiment apparatus recei~es an incoming si~nal, ~he apparatus executes the ~bo~e dat~ automatic trans~er pr~cessi~ only un~er the condit.ion that the subscribe~ number and subaddress of the incoming siqnal both coincide with associated ones of the registered subscriber numbers a~d subaddresses r~specti~ely. The ide~tification data IDs to ~e regist.ered in ~he recei~er I~ memory 45 may comprise only su~tsc~-iber num~ers or may ~omprise subsc~iber numbers added with associated subad~resses. ht least when such subadclresses are added to the associated s~bscriber numbers as in the lat~er, desired ones of the commurtication te~minals to which the data is to be transferred can be more finely spe~ified~

~ n either c~se (in both cases o~ su~sc~iber numbers with .ind without a~sociated subaddresses), ~he number of caller- identification data IDs (caller su~scriber number~) tcl be reqistered in the ~aller 1~ memory 44 may be se~ ~o have a one-plurality or plurality~one relationship with the number of receiver identification data IDs (receiver subscriber num~ers) to be registered in the receiver ID
memory 45 as associated with ~he calle~ ones.
In the case where these identifi~tion dat~ IDs are r~!gist.ered in ~he aboYe one-plurality rela~ionship (one caller and a pl~rality of receivers), a pictu~e data from the single c~lle~ communication terminal is transerred to the plurality of desired communication termin~ls at the same t;ime or on a time s~ries ~asis.
In the case where these identification data IDs are regist.ered in the above plurality~one rela~ionship (a pl.ura~.ity of callers and one receiver), pic~re d~ta s~par~ltely sent from the plurali~y of c~ r communication ~ermirlal are separately t~ansferred to the single desired receiver communic~tion terminal.
E.~planation has been made i~ the foregoing first embodiment on the assumption that these caller and r~cei~er ID memories ~4 and 45 a~e both memories incor~orated in the facsimile machine o~ the first embodi.ment, but one or both of the caller and receiver I~
m~mori.es 44 and 45 may comprise an external memory freely attachable to the body of the facsimile machine as sown by a broken line in Fig. 1~ When such an external memory is emp~oyed, the data of the c~llers and receivers concerning data t.ransfer can be freely carried. In addition, if the exteralnal memory is such a simple IC-card writing device, then t;he writing operation can be easily achieved ~t any place. From the viewpoint o~ reallzing the more f.Lexi~le applications of the presen~ apparat~s as a communication terminal, it is highly important to positively m~ke these memories 44 and ~5 in the form of such ~n external memor~.
E'~g. 3 s,hows a second embodiment of the ~ommunication termin~l apparatus of ~he present invention, even in which embodiment the ap~aratus is intended to be a facsimile machine connected to ~he ISDN, as in the first embodiment.
l'he ~pparatus of ~he second emb~diment, as shown in ~g. '-~, comprises, as a whole, a central controller 1 for performi~ general control over the embodiment apparatus, a pict.ure ..,er"oL~ 2 for temporarily storing therein picture data as necess~r~ under control of the central controller 1, a communication part 10 for perfor~ing mainly control and processin~ on ~he communica~ion of the embodiment apparatus, a console par~ 20 for perfo~mlng data or i~ormation transaction with the user (operator~, a picture p~ocessing part 30 for executing su~h picture pr~ce.sin~ as reading or w~iting a plcture da~a a~ the fa.~sim~le machine, and a second exp~nsion par~ 50 for reali~;ing auxiliary da~3 displ3y processing to be detailed l~ter in association with the fu~ctions of these parts 1, 10, 20 and 30. The parts other than the se~ond expansion part 50 are the same as those in the first embo~iment -a2~

appa~tus of Fig. 1 a~d thus the following explanation will be concentra~ed on the arrangeme~ an~ ~unction of the s~!cond expansion part 50.
~ s shown in Fig~ 3, the se~ond expansion part 50 includes an auxiliary-da~a display pro~ram memory ~1 for previously storing therein processing comm~nds to the c~ntral controller 1 in the ~orm of a progra~ to realize an auxiliary dat~ display processing to be expl~ined later, ~n ID register S2 or temporarily storin~ there~n a c~.ller subscriber number when an incoming sign~l received at. th0 communication p~rt 10 contains the subscriber number- as an identification data ID, a regis~er controller 53 $or contro1ling the reading a~d writing operations of the data (number~ of the ID registsr 52 on the basis of commands from the central controller 1, a caller ID memory 54 for previously ~egistering therein ~ single o~ a plurali~y of calle~ subscriber numbers as identification d~t~ IDs specifying associated callers (callers' c~mmunication termin~ls: ~acsimile machines), an auxiliary d~ta memory S5 for previously reqisterin~ therein a~xiliary d~ta including such proper noun data as the busine~ss titles to which the subscribe~s associated with the subscriber numbers belong and subscribers' names ~nd incluclin~ su~h documen~ data as notes on the s~bsc~ibe~s , and a memory controller 56 for ~ontrolling the reading ~nd wri~ing oper~tions of the data of the~e me~ories 54 and 55 in accord~nce with ~ommands from the central controller 1.
1~he subscriber numbe~ to be registergd in the c~ller I~ memory 54 ~s well as the auxiliary data to be r~gistered in the auxiliary da~a ~emor~ 55 are ente~ed throu~h the ~ey~oard 21 with the help of, for example, a suitable guide display on the screen of the displa~ ~2 r~spe~tively as the caller subscriber number o the auxiliary data to be transferred for automatic display and as, the~ specific ch~acter data~ When a plurality of s~ch caller numbers and ~ plurality of such auxiliary d~ta are re~gistered respectively for the same data to be transferred, these call~ subscriber numbe~s and a~xiliary data ~or the same dat~ are stored in the memories 54 and a~ associated with eaçh other in predetermined r~lationship, for ex~mple, by using the same or ass~ci~ted a~dre~s data.
Shown in Fiq. 4 is an example of the operstion of the embodiment app~ratus based on the func~ion (in particular, a program registered in the above auxiliary data display progr~m memory 51) of the second e~pansion part 5~. The auxili.ary da~a automatic display me~hanism of ~he apparcltus of the s2cond embodiment will be det~iled with refer~nce to Fig. 4.
Assume now that another communi~a~ion terminal (not shown f~csimile machine) connected to the ISDN issued a signal to the second embodiment ~pparat~s shown in Fig. 3.
Then the caller communication terminal fi~st sends to ~he ISDN ~ signal for calli~g the sec~nd emb~Aiment apparatus twhich signal is referred ~o as the calling sign~ he ~lling signal usually con~ains a data indicative of a -a~t-: . ~, .;
.

cealler subs~riber number previously designated to the sign~originator (caller? communica~io~ terminal.
l'he calling signal thus sent to the IS~N from the caller commu~ication terminal is recei~ed as an incoming call ~ignal ~t the network controller 11 of the embodiment apparatus through the ISDN line (D channel).
l'he second embodiment apparatus, when receiving the incomi.ng ~all sign~l at the network controller 11 and recogniæing the presence of the incomlng signal at the cent~cll ~ontroll~r 1 (step 201 in Fig~ 4), starts its processing i~ the following manner.
~ 1) The central controller 1, when r~cogni2ing the presence of ~he incoming signal on the basis of a notifi~cation ~om the ngtwork controller 11, check~
throu~h the network ~ontroller 11 whether or n~t the incoming signal contains the ~alle~ subs~iber number of the c~ller communication terminal (step 202 in Fig. 4)~
~ Z) When having determined that the caller subscriber number is no~ included i.n ths i~coming signal, the central contrc~ller 1 controls the em~odiment apparatus ~o perform its u~;ual incoming-signal informing operation~step 203 in Fi.q. d,)~
~ 3) When d~termining (~n step 202 in Fig. 4) th~t the cellle~ su~s~riber number is in~luded in the incoming si.gnal, the central c~ntroller 1 ca~seC the ~egister contr~ller 53 to se~ (store) the included caller subccriber number in the ID ~egister 52 (s~ep 204 in ~ig.

4). At this time, if another caller subscriber number (corre~sponding to the previous incoming signal) is already set in the I~ reqister 52, then the previous caller su~scriber number i~ replaced by the new one for its renewal, unless the ID reqister 52 ~s cleared each time the processing is completed.
(4) The central controller 1 next checks ~hether or not ~he c~ller subsc~iber number for ~pecifyin~ the caller is p~eviou~ly registered in the caller ID ~emory 54 (step 205 in Fic~. 4).
~5) 'rhe controller 1, when dete~mining ~ha~ the caller subscribe~ number is not registered, control the embodiment app~ratus t~ displa~ the subscriber ~um~er o~
the incoming signal, i.e., the subscriber number set in ~he r~ register 52 on the displ~y 22 through the console contrc)ller ~ (step 206 in Fig. 4) and subsequently to pe~rfoTm i~ usual incomin~-signal i~forming operation as i~ th~! above processinc~ (2) ~step 203 in ~ig. 4).
~6) The controller 1, when determing that the caller subscriber number included in the incoming signal is regist;ered in the caller ID memory 54 (step ~5 in Fig~
4)~ reads out associated one of the caller subscriber numbers from the caller ID mo~ y 54 thro~h the memory contrc~ller 56 and compa~es the read subscriber number with the s-lbscriber number set in the ~ register 52 (step 207 in Fi~. 4).
(7~ When determining to be a none-coincidence in subscriber numbe~ as the comparison result (step 207 in Fig. 4), the central controller 1 repe~ts the a~o~e -a6-processing (6)(step 207 in ~ig. 4) so long as other caller s~bscriber numbers are registered in the caller ID memory 54 (step ~Og in Fig. 4). When the central controller 1 determines th~t an~ one of the subscriber num~ers registered in the caller ID memory 54 does not coincide with ~he su~scriber number set in the ~D register 52, the controller 1 ~ontrols the embodi~ent apparatus to display the subscriber numbe~ set in the ID registe~ 52 on ~he displ~y ~ through the console controller a3 (step 206 in Fiq. 4) ~nd sub~equently to perform its usual incoming-signal informing operation as in the above processing (5) (step 203 in Fig. 4)~
~) When determining through the comparison (step 207 in Fig. 4) to be a subscriber number coincidence (step 20B in Fig. 4), ~h~ ~entral controller 1 reads o~t throu~h the ~e~o~y controller 5~ the a~xiliary data of the s~scriber ~egistered in the auxiliary d~2 memory 55 ~s associated with the coincided subscriber number (step 20~ in Fig. 4).
Subs~quently, the central controller 1 controls the present embodiment apparatus to also display the subscriber number set in the ID register S2 on the display 22 through the consol~ controller 23 as in ~he abov~
processin~ (S) (step 206 in Fig. ~) and then to perform its incoming-signal in~orming operation (step 203 in Fig.
4).
7'hrough the above p~ocessings of the app~ratus of the second embodiment, the business tile and name of the ~ller s~bscriber as well ~s a note on the subscirber can -a7 -be automatiçally indicated on the display 2simultaneously wit~ the reception of the in~oming ~allr ~g ~ r-esult, there can ~e eliminated such ~n inconvenience th~t ~,h~ party c~n be confirmed only after the ~pp~r~tuC
has received the tra~sac~ion data, i.e., only after the apparatus has been put in its communi~ation sta~e, thus realizing the smoo~he~ ope~tion o the incoming-~all processing.
The second embodiment apparatus is substantially the s~me ~s the first em~odim~nt apparatus shown in Fig. 1 with respect to the following points~
~ The reading control system of these subscriber numbers th~ough the memory controller 56 is not restricted to the aforementioned system but may be arbitra~ily employed so lon~ as the system allows the comparison or c~llation of all the subscriber number being registered in the caller ID memory ~4.
~ The Aforementioned subaddress m~y b~ po~itively utilized as an identifica~ion data ID uniqu~ly specifying the caller comm~nication terminals.
~ One or both of the caller ~ memory ~4 and the auxili~ry data memory 55 may comprise such an external memory freely detachable from the body of the communic~tion terminal appa~atus (~a~si~il e machine) as an ~C card.
~ ig. 5 shows a third embodiment of the communicati~n terminal apparatus of the present invention, even in which em~odiment the app~r~tus is also intended to be a t 334866 facsimile m~chine connected to the ISDN, as in ~he first embodiment~
The apparatus of thè third embodiment, as shown in Fig. ~, comprises, as ~ whole, a central controller 1 for perfo~ming general control over the embodiment apparat~s, a picture memory ~ for temporarily storing therein picture data as necessary u~der control of the central controller 1, a communication pa~ 10 for per~orming mainly oontrol and p~ocessing on the communication of the embodiment apparatus, a console part 20 for performing dat~ or in.formation transaction with the user (operator), a picture processing part 30 for executing such picture ~ro~essing as ~eadin~ or w~iting a picture data as the fa.~simile machine, and a third expan~ion part 6~ for r~alizing operational-mode automati~ selection pro~ssing of th~ third embodiment apparatus to be detailed lat~r in association with the ~unctions of these part~ 1, 10, 20 ~nd 30~ The par~s othe~ than the third expansion part 60 are the same as those in th~ first embodiment app~ratus of Fig. 1 or those in the second embodiment appar~us of Fig~
3 ~nd th~s the following explanation will be concentra~ed orl the arrangement and function of the third e~pansion p~r~ ~0.
As shown in Flg. 5, the thi~d expansion part 60 includes a mode autom~tic selection program memory 61 fo~
pre~i~usly storing therein processing comm~nds to the centr~l çontroller 1 in the form of a program to realize an operational-mode automatic selection pFocessing to be , explained later, an ~D register 62 for tem~ora~ily s~orin~
therein a caller subscriber number and/o~ a ~ubaddres~
when an incomin~ signal received ~t ~he communicatio~ part 10 contains the subscriber number and its subaddress as an identification data ID, a register controller 63 for controlling the reading and wri~ing operations of the data (number) of the I~ ~egister 62 on the basis of commands from t;he central controller ~, a caller I~ memory 64 for previously registering therein a single or a plurality of caller subscriber numbe~s as identi~ic~tion data IDs cpecifying associated caller communication te~minals and a single or a plurality of subaddresses as identific~tion data I~s speçi~ng the spe~ified communication terminals and the selected operation~l modes, an operational mode ~emory 65 for previoucly registering therein data indicative of the operational modes sele~table in the own cc~mmunication termin~l (present embodiment apparatus) in associ.ation with the subaddresses (in the pres~nt e~bodiment, only a part thereof), and a memory controller 66 for controlling the reading ~nd writing oper~tionC of the data o~ these memories ~4 and 65 in ~ordance with commands from the central controller 1.
~ xplanation will next be mad~ as to relationships b~twe~n the subscriber numbers and su~addresses as their acldtional data and as to relationship between the subaddresses and the asso~iated operational modes, respectively by referring to Figs. 6 a~d 7.
'~he subscriber number, as shown in Fi~. 6(a), is an identii~ation number data of a predetermined length previously designa~ed ~o one of su~s~ribers for the communiçat~on network. In othç~ words, the use~ cannot change the subscriber num~er freel~.
Meanwhile, the cubaddress is an iden~ification number data which can be freely determined and set by some parties among the subscribers of the communication network~ When an identical subs~riber number is d0signated to a plurality of communication ter~i~als, the subaddress is ~sually used, in many appli~ations, a~ a so-c~lled "t~rminal i~entifica~ion data" to specify one of the communication te~minals all havin~ the s~me subscriber number .
To this end, t~e present thi~d embodiment is arranged so thAt the subaddress is divided, $or exa~ple, as shown in Fig~ ~(b), into "function identification data" for specifying one of the set operational modes a~d "terminal ident.ific~tion data" for specifying one ~f the communication ~erminals. One of the operation~l modes can b~ identified, in particular, by the former "function iden~lfica~ion data".
5hown in Fig. 7 is an ex~mple showing relationships between the "fun~tion identif~cation data" and associated operational modes, in whi~h "function identification data"
01 specif.ies "relay multiple ~ddre~s" as an operational mode, "function identi~ication data" 02 specifies "remote multi-copy" as an oper~tional mode,..., and ~o on. That i~, the ~hird embodiment app~atus is intended, when a~

operational mode is specified b~ "function identiication data" in the sub~ddress in this w~, to identify and ~utomatica:Lly execute the specified operatio~al mode.
The subscriber n~mber ~nd its subaddress to be reqistered in the calle~ ID memory 64 ~re entered throuqh operator's keybo2rd 21 with the help of, e~g., ~ suita~le g~ide indication on the screen of the display 22 in such fc,rmat.s as shown in Fig. 6(a~ and ~b) in the form of number data which specify a caller communication terminal ~ap~le of specifyin~ ~he shif~ of the emb~dimen~
apparatus to such operational mode, the ~ase comm~nica~ion t~r~inal (the presen~ embodiment app~ratus) ~nd the operational mode the embodiment app2ratus can a~tomatically exec~te respectively. The operational mode d21ta t;o be regtsterçd in the op~ra~io~ mode memory 6~ ls also enterd throu~h the keyboard 21 with the help of, e.g., a s~itble guide ind~cation on ~he s~reen of the di.splay 22 in su~h a format as shown in Fi~. 7 in the form o~ a d~ta indicative of thç operational mode placed at the "iunc~ion identification data~ of the subaddress. When a plu~:Lity of such identification data and a plur~lit~ of such oper~ional modes are registered, the identification data :rD (subscriber number and subaddress~ and operatio~al mode data are stored in the memories 54 and 55 in predete~mined relationships with each other, or ex~mple, b~ using an identical or associated address data for the subscriber and its operational mode~
Fig. 8 shows an example of the operation of the - 3~--.

present embodiment apparatus based on the function (in particular, a program re~istered in the aorementioned mo~e automatic-selection program memory 61) of the third expansion part 60. The operationa~-mode automatic-selection mechanism of the third embodiment a~paratus will be detail~d in the followin~iby ~eferring to Fig. 8.
Assume now that another communi~ation terminal (not shown facsimile machine) connected to the ISDN issued a signal to the third embodiment appar~tus shown in ~i~. 5~
Then the caller communication te~minsl first sends to the I5DN a signal for calli.ng the ~hi~d em~odiment apparatus (which sign~l is referred to as the callin~ signal). The c~llinq signal usuall~ contains ~ data indicative of a çaller subscriber numbe~ previously designated to the signal-originator (caller) communica~ion ~erminal and subaddress ~s its additional data.
l`he cal~ing signal thus sent to the ISDN from the caller communic~tion terminal is received ~s an incoming c~ll signal at the network controller 11 of the embodiment apparatus ~hrough the ISDN lin~ (D channel).
The t;hird em~odiment apparat~s r when receiving th~
incoming call signal at the network controller 11 and re~ognizing the presence of the incoming signal at the central con~roller 1 (step 301 in Fig. 8~, starts its processing in the following m~nner.
(1) The cent~al controller 1, when re~ognizing the presence of the incomin~ signal on the basis of a no~ification from the network controller 11, checks thro~gh the network controller 11 whether or not the incomlng signal contains the c~ller subscriber number of the caller communication termin~l (step ~02 in Fig. 8).
(2) When having determined that the caller subscriber number is not included in the incoming signal, the central controller 1 controls the embodiment apparatus to perfor~
its usual incoming-signal pro~es-cin~ operation ~step 3~3 in Fig. 8). In this case, the setting of the control conditions is arbitrary ~nd of course, the central can~roller 1 ma~ control the e~bodiment apparatus to select and perform an incoming-signal reje~tion processing to be expl~ined 1ater (step 309 in Fig. 8).
~ hen determining ~in step 302 in Fig. 8~ that the caller subs~ribe~ number is included in the incoming signal, the central controller 1 causes the register controller 63 to set (s~ore) the included caller su~scriber number in the I~ re~ister 6Z ~step 304 in Fig.
8). At this time, if ano~her caller subsc~iber number (corresponding to th~ previous incoming sign~l) is Already s~t in the ID register 62, then the previous caller subscriber num~er is replaced b~ the new one for its r~newal, unle~s the ID ~egi~ter 62 is cle~red ea~h time the processing is completed. Furthsr, i~ the subscriber n~ber o the incoming siqnal is attached with a su~address, then the subaddress is also set in the ID
register 62 (4) The centr~l cont~oller 1 next checks ~hether or ~o~
c~ller s~bscriber number ~or specifying the caller i5 -34~

' ; ' ' I` ~ .
-, ': . - :

p~e~iously re~istered in the caller I~ memory 64 (step 305 in Fig. a)~

(5) The cont~oller 1, when determining that th~ caller subscriber number is no~ re~iste~ed, control the embodiment apparatus to perform its usual incomin~-signal processing operation as in the above processing (2) (step 303 in Fig~ 8).

(6) The controller 1, when determing ~h~t the caller subscriber number included in the incoming signal is registered in the caller I~ memory 64 (step 305 in Fig.
8), reads o~t associa~ed one of the caller su~sc~iber numbers from the caller I~ memory 64 through the memory controller 66 and compares the read subscriber number wi~h the subscr:iber number set in the ID register 62 (step 306 in Fig. 8)~

(7) When determinin~ to be a none coincidence in subscriber num~er as the comparisan recult ~step 3~7 in Fig~ 8), the central controller 1 repeats the above processing ~6) (step 306 in ~ig. 8) so lon~ as other caller subscriber n~mbers ~re registered in the caller I~
memory 64 (step 308 in Fig. ~). When the central controller 1 determines that any one of the subscriber numbers regis~red in the ~allçr ID memor~ 64 does not coincide with the subscriber number set in the ID regts~er 6~, the controller 1 controls the embo~iment apparatus to ~o perform a usual incoming-signa~ rejection p~cessing (step 309 in Fig. 8).
~ 8) When determining throu~h the comparisan (step 306 in Fig. g) to be a subsc~lber num~er coi~cidence (step 3~7 in Fig. ~), the central controller 1 then makes reference to the contents of the I~ register 62 and checks whether or not the subscri~er number is attached with a subaddress (s-tep 310 in Fig. 8).
~ g) ~he controller 1, when determining thro~gh the check that any subaddress is not att~ched to the s~bscriber n~m~er, also controls the embodiment apparakus to per~or~
it.s ~su~l incoming-signal processingoperation ~s in the a~ove processing (2) or (~ tep 303 in Fig. 8~.
l~O) When d~termining through the comparison (s~ep 310 in Fig. 8) th~t a subadd~ess i~ attached to the subscri~er number, the central controller 1 further reads ou~ through the memc~ry controller 66 the base terminal subaddress registered in the caller ~D memory 64 as associated with the coincided subscriber number, and checks whether or not the read subaddress coinçides with the subaddress being s~t in the ~D register 62 (step 311 in Fig. 8).
~ 11) As the ~esult of the check, if the con~roller 1 determines to be a subaddress coincidence, then it con~rc)ls the em~odiment apparatus to perform its incoming-signa]. rejecting operation as in the above processin~ (7) (step 3~ in Fig. a).
~ 12) The central ~ont~olle~ 1, when determining through the above check (step 311 in Fig. a) to be a subaddress coinci.dence, first performs its incoming-sign~l processin~
operat;ion ~n accordance with the predetermi~ed tr-~ns~ission control procedur~ (st~p 312 in Fig. 8), re~ds -~6-out through the memory controller ~6 one o~ the opexational mode d~ta registered in the operational-m~de me!mory 6S and correspondinq to the "function identi.fication dat~" in the coincided subaddress. and then contr~ls the present embo~iment apparatus to be autom~ically shifted to the operational mode indicative o~ th,~ re~d-out oper~tional-mode data (s~ep 313 in Fig.

8~.
1'he above processing of the third embodiment appar~tus en~bles the reali~-2t~0n of remote ~ontrol of ~he ~hird embodimen~ apparatus through a control terminal or specific relay co~munication terminal (regist~red in the c~ller ID memory 64). That is, so long as arbitrary numbers and d~ta a~e p~eviously registered in the caller I~ me~or~ 64 and the oper~tional-mode memory ~5, all the proce~:sing of the registered operational modes can be autom~l~ically attained throu~h the communication terminals havint~ ~hese registered numbers, even if any operator is absenl. at ~he embodiment apparatus, thereby realizinq more flexible and efficient utiliza~ion of these communication t~rminals~ In addition, since such rgmote control is effected independentl~ o$ the communication protocol, the operat~ional-mode automati~-selection processing of this embod.~ment .is gener~lly valid even o~ c~mmunication t;erminals that are man~factured b~ different makers and ~perat.ed a~cording to different communication protocols.
rrhe above operational-mode automa~ic-selection proce:3sing has been carried out only when not only the su~scrlber number but also its subaddress coin~ides with the registered one as shown by step -~11 (the above p~ocessing (10)) in the ~oregoing embodiment based on the operat.~onal example shown in Fig. 8. However, such processing as shown, for e~ample, in Fig. q ~ay al~o be employed. That i5, when the central controller deternlines to be a subscrib~r number ~oincidence (step 307 in Fig. 9) and there is a s~baddrsss in the incoming sig~al (step 310 in Fig. g), the controller performs its incomi.ng-sig~l processing operation in accordance ~ith the predetermined tr~nsmi~sion control procedure (step 312 in Fi~ nd subse~uently if the operational mode data correspondin~ to the "function ide~tificatlon data" in the subaddress is ~lre~dy re~istered in the operational mode memory 65, then the controller 1 rea~s out throu~h the m~mory cont~oller 66 the registered operational-mode data and ~ontrols the present embofl~nt apparatus to be auto~tically shifted to the oper~tional mode indicative of the read-out operational-mode data (step 314 in Fig.

9) 1~he third embodiment apparatus is also substanti~lly the same as the foregoing ~mbodiment apparatuses wi~h respec:t to the ~llowing points.
~ Th~ readinq control system of these subscriber numbers through the memory ~ontroll~r 66 is not restricted to the ~orementioned ~ystem ~ut may be arbitraril~ employed so long as the system allows the comparison or coll~tion of ~ll the s~bs~riber number being registered in the c~ller -3g-I~ me~ory 64.
~ One or both of the caller I~ memory ~4 and the auxiliary d~te~ memory 65 may comprise s~ch an external memory freely detachable from the body of the communication terminal apparatus (f~csimile machine) as an IC card.
E'ig. 10 shows a fourth embodiment of the c~mmunication terminal 2pparatus of the present invention, even i.n which embo~m~nt the apparatus is a}so intended to be a ~acsimile machine connected to the ~SDNr e~s in the ~irst embodiment.

The parts other than the fourth e~pansion part 70 are the same as those in the foreqoin~ e~bodiment apparatuses and thus the following expla~at.ion will ~e co~c~ntrated on the arrangement and funl~tion of ~he fourth expansion part 70.
As shown in Flg. 10, the four~h expansion part 70 includes a return-messa~e t~ansfer progr~m memory 71 for previc~sly sto~ing therein p~ocessing commands to ~he central controller 1 in the form of a proqram to realize an operation~l-mode automatic selection processing to be explai.ned later, ;~n ID register 72 for temporarily storing therein a caller subsc~iber nu~ber when an incoming si~nal r~celved at the communicati~n part 1~ contains ~he subsct iber num~er as an identification data ID, a register c~ntroller 73 for ~ontrolling the readinq and writing operat;ions of the d~ta (number~ of the ID re~ister 72 on the basis of commands from ~he central controller 1, a celller ID memory 74 for further temporrily ~toring and regist;erin~ ~herein the subscri~er number (ide~tification delt~ r~) that was received when the embodiment apparatus is pu~ in its com~unication disable state, i.e., that was temporarily stored in the ~D register 72, a ~emory controller 75 for controlling the reading and writing operat:ions of the data of these memories 74 in accordance wi.~h commands from the central cont~oller 1, a message memory 76 for previously s~oring therein su~h a document data :Lndicative of a return message ~s sho~n, fo~ example, in Fig. 11, and a recordin~ paper sensor 77 disp~sed in ~he recor~er 35 for always detecting the presence or absence of an out-o- reco~ding-paper state.
With such a return me-~sage as shown in FIg. 11, its -~0 -de~scription matters are entered through the keyboard 21, fc,r e~ample, under a suitable guide indication on the screen o~ the display 22 and its time description matter, ir, particular, is automatically listed through the central contr~ller 1 (usually incorporating a timer) during the tr~nsmission of ~he return message.
~ 'ig. 12 shows an example of the operation of the present embodiment apparatus based on the function (in p~rti~:ular, a program registered in ~he aforementioned return-mess~ge transfer program memory 71) of the fourth exp~n~ion par~ 70. The return-message transfer mechanism of the f~urth embodiment apparatus will be detailed in the f~llowing by referring to Fiq. 1~.
Assume now that another communication terminal ~not shown facsimile machine) connected to the ISDN issued a si.~nal to the fourth embodiment apparatus shown in Fig.

10. Then the caller comm~nic~tion terminal firs~ sends to the ISDN a signal for calling the fourth embodiment appar~tus (which signal is referred to as the calling si.gnal)~ The c~lling signal usually contains ~ data ir~dicative of a caller subsçriber number previou~ly designated to the signal-originator (caller) communi~ation termin~l.
'rhe calling signal thus sent to the ~S~ from the caller communication terminal is received as an ~ncoming call signal at the netw~rk controller 11 of the embodiment apparatus through the ISDN line ~ ~hannel).
~e~nwhile, the central ~ontroller 1 is executing a normal façsimile operatio~ routine under ~he conditionths~ the detection ~utput of the reco~ding~paper se~sor 77does not indicate ~n out-of-reco~ding-paper state ~s~eps 401 and 402 in Fig. 1~). Under such a condition, if ~he çmbodiment appa~atus receives the above incomin~-~all sign~, then the central controlle~ 1 controls ~he e~odi.me~t apparatus to pe~crm its normal incoming-call a~swering operation. In this case, a pic~ure data transmitt~d on the inco~ing-call signa~ is sui~ably demodula~ed th~ough the communication ~ontroller 12, trans~e~re~ to the picture buffer pro~essor 37, and then re!corded on a re~ording paper through the recorder 35.
Under the condition that the dete~tion output of the r~!cording-paper se~so~ 77 indic~tes an out-of-paper state, i.e., that the embodimen~ apparatu~ (facsimile ~achine) is put in its c~mmunication disable state, on ~he other h~nd, if the netwo~k controller 11 receives the in~oming-call signal. as mentioned a~ove, then the fourth embodiment apparatus starts the following processing operatlons in sequerlce on the b2sis of the determin~tion of pre~en~e of the incoming si~nal by the central ~ontroller 1 (step 403 in FIg. 1~ the case of the detection of such an out-oi-p~per state, ~he central controller 1 also informs the operator of the out-of-pape~ by means of, for example, an o~t-of~paper message indicated on the display Z2 th~ou~h the console controller 23, where~y the opera~or can quickly condu~t such resto~i~g work as recording-paper supplemen~ o~ the ~asis of such message displ~.
~a-In parallel w~th the abo~e operator's work, ~he fourth embodiment apparatus carries out the following processinys.
(1) The central controller 1, when determing the presence of th~ incoming signal on the basis o the notification from the network controller 11, further determines throu~h the netowork controller 11 ~he inclusion o$ the subscriber number of the ~aller communication terminal in the incoming-call signal ~nd sets (stores) through the register controller 73 the caller subscriber number in the regis~er 72 (step 404 in Fig. 12). In this connection, if another subscriber number (whi~h is an old subscriber number included in the pre~ious incomin~-call signal) is already set in the ID re~ister 72, then the old subscriber num~er is updated to this newly receive~ one, except that the memory o~ the I~ re~ister 72 is cleared each time the procescing is completed.
(2) The ~ntral controller 1 th~n s~ores ~nd registers the çaller subscriber number set in the l~ re~ister 7~
int~ the caller I~ memory 74 ~hrough the memory controller 7S (step 405 in Fig. 12).
(3) ~ring the above oper~tion, the central cont~oller 1 is continuously monitoring whether or not ~he operator' 5 restoring work h~s been completed on the basis of ~he detection output of ~he recording-paper sensor 77 or an ope~tor's work-completion report throu~h the keyboard ~t.
At the same time, the ~ontroller 1 chec~s whether or not th.e embodiment apparatus is ln a communication able state - ~3 ~

or signal reception able state (step 4~6 in Fig. 12).
~urlng the communication dis~b~e state of the embodiment apparatus, if the apparatus receiv~ a plurality of in.comi.ng call signals from a plu~ality of callers, then it repeates the above p~ocessings (1) and (2) for each recept.ion of the incoming signals and registers a plurality of sub~criber numbers of the plurality of callers in the caller ID memory 74.
~4) The central cont~oller 1, when determing to be ~
signal-reception a~le st~te (step 406 in Fig~ 12), reads out under the memo~y controller 75 the s~bscriber numbers regist;ered in the ~aller Il:) memory 74 on a one-after-one basis and performs its ~alling p~ocessin~ over the read-out subscriber number through ~he communication part 10.
The central cont~oller 1, after being put in its da~a-transaction enable state with respect to ~he party (called~party or ~ll-receiver) ~ommunication terminal (facsimile machine), reads ou~ the associa~ed return-messa~e data from the message memory 76 and transmits i~
to the party communication ~erminal newly put in th~
commurlic.~tion state ~st~p 407 in Fig. 12~.
Throu~h ~he above processings of the fo~rth embodiment apparatus, the re~urn message thus tr2nsmitted can be received and reco~ded in the new party communication terminal (facsimile machine) through a usual operational rou~ine. Thereore, the party communic~tion terminal can im~ediately know, on the ~asis of ~he r~ceived and recorded message, that ~he presen~ e~bodiment -44~

- - -.

apparatus has been returned to the communication ~ble state and thus it can a~ain c~ll the present embodiment appar~tus at any time t~ere~fter~ Wi~h respe~t to this point, the present embodimont apparatus can reduce useless ope~ations and waiting time to a large extent, when compared with the prior art which re~uires requent calling o~e~a~lons wi~hout k~o~ing its restoration time, whereby the operator can comfortably communi~ate with the party wi~hout causing ~ny irritatin~ feelin~.
Thouq~ explAnation has been made, ~or brevity of explanation, as to only the case where ~he apparatus is put in the communication disable st~te when it is out of r~cording-paper in the foregoing embodi~ent, it will of course be noted that the present invention is not limit~d t~ ~he specific e~bodiment but may be arranged so that th~
~c~mmunication disable state of the ~ppa~atus is caused by o~her fa~tors such as a busy state in a copyin~ mode and so on, in addition to the above out-of-paper state.
The transfer service af the above return mess~ge h~s been car~ied out with respect to callers so long as the caller subscriber numbers are included in the respective incoming signals from the callers in the o~egoing embodiment~ ~o~eve~, the pressnt embodlment m~y also ~e modifi.ed so that particular c~ller su~scriber numbers are pxeviously reqistere~ as in the first and ~hird embodiments ~nd the r~turn-messa~e transfer service is carried out onl~ for the c~ller communication terminals of these reqistered subscriber numbers~

- ~5 -Fig. 13 shows ~ fifth embodiment of the communic~ion terminal apparatus ~f the present inventio~j even in which embodiment the apparatus ie intended to be a facsimile machine connected to the ISDN, ~s in the foregoing embodiments.
1~he apparatus o~ the fifth embodiment, as shown in Fig. 13, comprises, as a whole, a ~entral ~on~roller 1 for perorming general control over ~he embodiment apparatus, ~ picture memory 2 fo~ temporarily storing therein picture data ~s ne~essary under control of the centr~l con~roller 1, a communication p~rt 10 f~ performing mainly ~ontrol and proçessing on th~ communica~ion of the embodiment apparatus, a console part 20 for performing dat~ or inform~tio~ t~ansaction with the user (oper~tor), a pi~ure processing part 30 for exec~tin~ such picture processing as reading or writing a picture data as the facsimile ma~hine, ~nd a fifth expansion part 80 for realizing incoming-sgin~l condition c~nt~ol or managemen~
to be detailed lat~r in ass~ciation with the functions of these parts 1, 10, 20 and 3~. The parts o~her ~han th~
fifth expansion part 8~ are the same as ~hose in ~he foregoing embodiment apparatuses and thus the $ollowing explanation will be con~entrated on ~he a~ran~ement ~nd f~lnction of the fifth expansion part 8~.
As shown in ~ig. 13, the fifth expansion p~rt 80 includes an incoming~si~nal-~ondi~ion management program memory 81 for previously storing therein processing comm~nds t:o the central controller 1 in the form o a -~6--- ~ 3348~6 progr~m to realize inc~ming-si~nal condition management to be explained later, an I~ re~ister 82 for temporarily storing therein a caller su~scriber number when an in~oming signal recei~ed at the com~unication part 10 cont~ins the subscriber number as an identificatio~ dat~
~D, a register controller 83 fo~ controlling the reading ~nd writi~g oper~tions of the data (nu~ber) of the ID
register 82 on the basis of commands rom the ~entral con~roller 1, a caller ID "leh.~L~ 84 for previously regis~erin~ therein, as necessary, a single or a plurali~y of caller subscriber numbers as identification data I~s specifying associated caller communication termlnals, a me~ory controller 85 for controlling ~he reading And w~iting operations of the data o~ the memory 84 in accordance with commands from the ccntral controller 1, a timer 86 for executing timing opera~i~n on ~he basis of a t t mer time set thr~ugh the console p~rt 20, and a flag setter 87 for setting or resetting a flag ~ an index for the :incomin~ signal condition managemen~ under the predetermined ~ont~ol of the central controller 1.
The subscriber number or numbers to be re~istered in the caller ID memory ~4 is entered as necessary through th.e keyboard 21 with the help of, for example, a suitable guide indi~ation on the screen of the display 2~, as a single or a pl~rality of specific caller subscriber numbers on the basis of which the assoGiated incoming signa]s are granted or re~ected. Further, the timer time to be set at the timer 86 i~ entered also through the keyboard 21 with the help of, for example, a suitable g~ide indication on the sc~een of the display 22, as an e~fecti~e time for the setti~g o~ the conditi~n of the i~coming signal from the particular caller tthe ~anting o~ rejection of the in~oming signal)~
The flag settin~ and res0t~in~ of the flag setter 87 is ~ontrolled by the central controller 1 in accordance with such a flag control routine as shown in ~ig. 14, the flag being used as an idex indicative o~ whethe~ or not the setting of the a~ove in~oming-signal condition for the s~lbscribe~ n~mber registered in the c~ller ID memory 84 and for the tlmer time set at the timer 86.
~ `or example~
~ he central controller 1 controls the flag setter 87 to ~e put in its set ~tate (step 503 in Fiq. 14) in accordance with the flag contro~ routine when ~he AND
c~ndition is satisfied that the subscriber ~umber is already registered in the caller I~ memor~ 84 (step 501 in Fig. 14) and that the ~imer time is ~lready set at the timer 86 (step 502 in Fig. 14).
~ 2) ~hen the subsc~iber nu~h~r registered in the callex II~ me00~y 84 i~ dele~ed durin~ ~he a~ove timer time pç~riod, that is, the regist~ation of the subscriber num~er specifying the caller is released (step 504 in Fig~
or when the ~imer 86 generates a ~imer signal indicati~e of ~ts time-up (step 505 in ~ig. 1 4), the central controller 1 causes the 1~g setter 87 to be put in its rt~set state (step 506 in Fig. 14).

~ ~8--Fig. 15 shows an example of the operation of the present embodiment appa~atus b~sed on the function (in particularr a program registered in the a~orementioned incoming-s:ignal condition man~gement program memory 81) o~
the fifth expansion part 80 . The incoming-signal condition man~gement mechanism of the fifth embodim~nt appara~s will be de~ailed in the ~ollowing by referring t~ . 15~
~ ssume now that another communic~tion terminal (not shown facsimile mac~ine) con~ected to the ISDN issued a slgna~ to ~he fifth embodiment appara~us shown in Fig. 13.
Then the caller communication termin~l first sends to the ISDN a signal for calling the fi~th embodiment apparatus (which signal is refer~ed to as the ca1ling signal). The calling si.gnal usual~y contains a data indicativç ~f a caller subs~riber number previously designated to the signal-originator (caller~ co~munication terminal.
I`he calling signal thus sent to the IS~N from the czller commu~ic~tion terminal is received as an incoming call signal at the ne~work cont~olle~ 11 o~ the embodimen~
apparatus ~hrough the IS~N line (D ~hannel).
The fi~th em~od1~nt apparatus, ~hen receivinq the incoming ~all signal at the network con~roller 11 and rec~gnizing the presence o~ the incoming signal at ~he c~ntral cont~ller 1 (step 511 in Fig~ 15), starts its processin~ in the ollowing m~nner~
~1) The centr~l controller 1, when dete~mining the presence of the incoming signal on the basis o~ an _ ~9 _ incoming-s;ignal notification from the network controller 11, first che~ks whether or not the fl~g setter 87 is in its set st~te tstep 512 in Fig. 15).
(~) When determining through the check that the fla~
setter 87 is not set, the central controller 1 cont~ols the present embodiment apparatus to perform its usual incoming-signal processing ~per~tion (step 513 in Fi~.
15).
~ 3) If determining through the check (step 512 in ~ig.
1~) that the flag setter 87 is set, then the central controller 1 j~dges thro~gh the ne~work controller 11 whether or not the subscriber number of the caller c~mmunication terminal is included in the incoming signal (~tep 514 in Fig. 15).
~ 4J When determining that the caller subscriber nu~ber is not in~luded in the incoming signal, the Gentral controller 1 controls the embodiment apparatus ~o perform its incoming-signal rejeçtin~ oper~tion to r~ject the ~eception of th~ incoming signal tstep 515 in ~ig. 15).
(S) When determinin~ through the judgement (step ~14 in Fig. 15) t.hat the calle~ su~scri~er number is included in the incoming sign~l, the central controller 1 causes the r~gister eont~oller 83 to set (store) the included caller subs~riber number in the I~ register 82 (step S16 in Fig~
15). At this time, if ano~her caller subs~riber number (corresponding to ~he previous incoming signal) i~ already set in the I~ ~egister 82, then the previous call~r subscriber number is repl~ced ~y the new one for its -- 1 3 3 4 8 66 rene~al, ~nless the ID register 82 is cleared each time the processing is completed. Further, if ~he subscriber number of the incoming signal is attached with a subaddress, then the subaddress is also set in the ID
register 6~.
(6) The ~ntral controller 1 then ~eads out one of ~h~
subs~riber numbers from the caller ID memory 84 through the memory cont~oller ~S and collates or compares the read-out subscriber number with that set in the ID
regis~er 82 (step 517 in Fig. 15)~
~ 7) When determining to be a none-coincidence in subscriber number as the comparison result (step 5t8 in Fig. 15), the central controller 1 repeats the a~ove processing ~6) (step 517 in Fig. 15) so long as other caller subscriber numbers are registered in the ~aller I~
memory 84 (step ~19 in ~ig. 1~). When the c~ntral controller 1 determines that any one of the subscriber n~ers registered in the caller I~ memory 84 does not coincide with ~he subscriber number set in the I~ register 8~, the controller 1 controls the embo~i~en~ app~r~us to perform the incoming-signal reje~ting operation (step 515 in Fig. 15) as in the above processing (4).
t8) When determining through the comp~rison ~step 517 in Fi.g. 15) to be a su~scriber number coincidence (step 518 in Fig. 15), the central controller 1 determines that it is data transmission from the caller for which the apparatus accepts its incomi~ signal and controls the present embodiment apparatus to perform its usual -5~ -.
incoming-sign~l processing ope~ation (step 513 in Fi~.
1$).
In this way, through the abo~e processings of the fifth embodiment apparatu~, the app~ratus can automatically execute its incoming sign~l processing operation unde~ dif$erent conditions (A-1) and (A-2) that the flag setter 87 is set o~ not as fo~lows.
~ -1) Wh~n the flag of the flag setter 87 is set, that is, when the parti~ular subscribe~ n~mber on the ~aller is previously registered and the timer time is effective, the en1bodlment appa~tus answers to the call only from the registered subscriber and per~o~ms the incoming-signal p~ocessing operation in response ~o the incoming call while re~ects for calls from the other subscriber-~ not registered.
~ A 2) If the flag is not set, the embodiment apparatus answers to cal1s even from any s~bscribers and performs the incoming-~ignal processing oper~ion, ~hat ~s, the apparatus is put in an open sta~e to all the subscribers~
~ ccordin~ly, the modification of the incoming-signal conditions to, e.g."the apparatus recei~es data (pic~ure data) only from company A d~ g one hour ~lone and then accepts all d~ta received thereafterN can be freely realized e~en in ~he absence of any operat~r, ~o long as the aforementioned settin~ for the caller ID memor~ 84 and t:imer 86 is previously effected a~ necessary.
In the foregoing embodiment, the above incoming-signal condition (A-1) or (A-2) has been set a~cording to the p~esence or absence of the setting of the ~lag -~etter a7, but the present inve~tion is not restricted to the particular example~ For example, when the incoming-signal ~ondition control program for the memory 81 is set to cause such operation as shown in Fi~. 16, the present appar~tus may similarly operate as follows depending on the presen~e o~ absen~e of the settin~ of the flag setter 87.
~B-1) When the flag oi the flag setter 87 is set, that is, when the partic~l~r subscrlber n~mber o~ the caller ls previously regi.st~red and the timer time is effective, the embodiment apparatus answers to the call only ~rom ~he r~!gistered subscriber and performs the incoming-signal pro~essing operation in response to the incoming call ~hile re.jects fo~ calls from the other subscribers not registered.
~B-~) If the flag is ~ot set, the em~odiment apparatus r~jects incoming signals rom any subscribers, that is, the appar~tus is put in a closed state t~ all th~
subs~ribers.
For example, when the incoming-signal condition contxol pro~ram fo~ the mem~ry 81 i5 also set ~o caus~ su~h operation ~s shown in Fig. t6, the present apparatus may si.milarly oper~t~ as follows depending on the presence or ahsence of the settin~ of th~ $1ag setter 87.
~C-1) Wh~n the flag of the flag setter 87 is set, that i~;, when the particul~r su~scriber nu~ber on ~he calle~ is previously registered and ~he timer time is effective, the .

embodiment apparatus rejects the recep~ion of an incomin~
call only from the re~istered subscriber while normally answers to calls from the othe~ subscri~er-q not registered and p~rforms its incoming-si~nal processing opera~ion.
(C-2) If the fla~ is not set, the embodiment apparatus r~jects incoming si~na1s from any subscri~ers, that is, the apparatus is put in ~ closed state to ~ll the subscribe~s~
F~ther, when ~he incoming-signal con~ition control program for the memory 81 is ~et tR cause such operation as shown in Fig. 16, the present ap~ara~us ma~ similarly operate as follow~ depending on the presence or ~bsence of the ~etting of the flag setter 87.
~ D-1) When the flag of the flag setter 87 is set, ~hat i-c~, when the particular subscribe~ num~er on ~he ~aller is pre~iously reglstered and the ti~er time is effec~ive, the embodiment apparatus re~ects the reception of an incoming call only f~om the registered subscriber while normally answers to c~lls from the othe~ s~bscribers not regis~ered ~nd performs its incoming-signal processing opera~ion.
(~-2) If the flag is not set, the embodiment apparatus answers to ~ncoming signals from any subsc~ibers and perform the incoming-signal processing operation, that is, the ~pparatus i~ put in an open st~te to all the subscribers. It goes without saying ~hat these incoming-s:Lgnal condition con~rol programs may be previousl~
prepared to be selected fr~ely as necessary~
Although the timer 86 has been provided and the flag . - 5~ -setter 87 has been set on th~ A~D condition that ~he subscriber number is p~e~iously registered in the caller I~ memory 8~ and that ~he timer ~ime i5 previously set in the ~imer 86 in the foregoin~ fif~h apparatus shown in Fig. 13, the provision of the ti~er ~6 is not the essential requirement of the fifth embodiment. In other wc,rds, the 1ag setter a7 may also be set only under such condition that the subscriber num~e~ is previously r~gis~ered in the caller ~ memory 84.
Although the communication netw~rk has been intended to be the IS~N and the ~pparatus has been intended to be a facsimile ma~hine in ~ny of the foregoing first ~o fif~h embodiments, the communication terminal appa~atus of the pl~esent invention is, as a matter of course, no~
r~stricted to these particular ISDN and fscsimile machine but a telephone set, a telex equipment or so on other than the facsi~lile machine may be emplo~ed, in pa~ ular, as the commu~ication terminal.
The dif~erent ~unctions o the communi~ation terminal apparatuses in a~cordance with the present invention have been illu~rated sepa~ately as the fo~egoing first t~ fi~th ernbodiments in the foregoin~ explan~tion. However, ~he respecti~e expansion parts in ~he respective embofli rents may be arbitrarily selected and combined to more effe~tively improve ~he user inte~face and communication effi~ien~y. That is, in actual applications, these embodiments m~y, o~ course, be utilized in a~bitrary ~ombination ~herebetween as ~exessary.
