to a single for all subscribers may connect for reserved, common telephone line (II.Leitung) of the dialing machine, over which he then:
- Can dial the second participant of his own phone line, or
- Can establish a telephone connection, even if the second subscriber has already occupied their own telephone line.

Description

The The invention relates to a method and an extended circuit arrangement for the supplementary circuit to connect of 2 telephones on a telephone line with own call number, whereby also a call connection possible under the two phones is.

little one + middle dialing systems are only for designed a certain number of telephone lines. Do you want to go? Connection of a Telefones at the last telephone connection still another telephone connect, so must one larger dialer to be bought.

Often it would suffice if connected to some phones 2 phones would - in particular then when the call volume not so big.

There are already possibilities to connect 2 telephones to a telephone connection with the help of an automatic changeover switch (AWADO) - see the patents: DE 36 33 561 C1 / DE 40 36 405 C1 ua - IPC: H04M 1/72, but in the (incoming) call are not distinguished and exactly d. wrong participants can pick up the phone.

For large dialing systems, there are communal connections for (line) bottlenecks - see IPC: H04M 13/00. For smaller dialers such are not provided. The patent DE 44 35 034 C1 shows a solution that is also possible with smaller dialers.

however will be with you from the dialer two telephone numbers / telephone lines needed!

The publication DE 199 40 801 A1 shows a solution, how to dial the desired subscriber with different numbers, although both phones are connected to only one phone line!

However, there are two problems:
It is not possible to establish a connection between the two telephones and if one telephone has seized the line, the second telephone is "dead".

task of this invention is to provide an extended supplementary circuit where a connection between the 2 phones is possible, or that of a 2nd Telephone also a telephone conversation setup possible is if the 1st telephone is the common, technical telephone line already occupied.

• – sowohl zu einen x-beliebigen Teilnehmer [wenn der 1.Teilnehmer mit seinem Telefon schon die Telefonleitung mit dem Automatischen Wechselumschalter (AWADO) belegt hat] oder
• – zum anderen Teilnehmer/Telefon, der am gleichen Automatischen Wechselumschalter(AWADO)/ der gleichen technischen Telefonleitung angeschlossen ist.

Solution: There should be a second connection path (a common one for all) from each telephone via which a connection can be established within the dialing system:

• - to any other subscriber [if the 1st subscriber has already assigned the telephone line to the automatic changeover switch (AWADO) with his telephone] or
• - to the other subscriber / telephone connected to the same automatic changeover switch (AWADO) / the same technical telephone line.

Produced This can be done by a "2nd line key" (2.LT) of a simple In-line system, with a single allowed reserved telephone line / Phone number to the "outside line the series system "connected which goes to every phone (looped) and to d. single "inner connection line (s)" the output of the Automatic changeover switch (AWADO) is connected.

Thus, no such high line overhead is necessary, the "series system" is relay-controlled, so that only one control line to the extended supplementary circuit (ERWS) must go from the phone and the many wiring is done within this. A circuit of a series system see patent specification / layout in the DPK: 21 a ³ 13/10 key-controlled series systems:
DE-AS 1 006 014 only 1
DE-AS 1 219 536 only in the illustration the AT button [Rest unintressant!]
DE-AS 1 182 305 only the office keys [Rest unintressant!]
DE-AS 1 062 753 Overall function of a series system
[but confusing in the presentation!] ua!

There but all the functions of a serial system are not needed, are the first two writings already expressive.

Of the Contact record of the office keys (AT) of all subscribers / telephone sets are simply connected in series [hence the name: Reihenanlage].

There but a whole lot of cable wires are needed, you already are up early the idea came to replace the office key with relay contacts, so only the relay must be controlled: DE-AS 871 774 or DE-AS 1 190 055 However, there are still several contacts from the button used, which are actuated to control the corresponding relay got to!

There However, not all the functions of a series system are required - sufficient it off, if only one key with a [toggle] contact, here 2nd line key (2.lt) called, with the contact contact spring activates the relay.

Maintained is the relay - 2.Leitungsrelais (2LR) called - by the relay coil with a holding contact (2lr ^V ) to a hold-and-busy line with the connection (hbl) is switched.

There it for reasons of economy no disconnect key is to be given, the end of the conversation by a relay relay (B) with two - off establish the magnetically and electrically symmetrical relay coils found, with one each in the a-wire and one in the b-wire - at the beginning the one, single, common telephone line (II.Leitung), the directly from the dialer comes - switched is.

Parallel to the relay coils are each a capacitor (C1) b.z.w. (C2) switched over which the alternating current [component] should flow.

Over a third, high-impedance relay coil of the relay relay (B) see later.

Construction:

In addition to the structure described in the solution, the following:
The relay relay (B) has a Folgeumschaltkontakt (b ^I ), whose common, middle contact spring is at plus (+) and at the inner rest contact spring is a terminal (ak ') to which a Ansteuerkette with all 2.Leitungs = buttons (2 .LT) - connected in series - is connected.

At the work center contact spring is the holding-and-busy line to the terminal (hbl) to which each of the holding contacts (2lr ^V ) of all / 2.Leitungs = relay (2LR) are connected
[NB: an outer normally closed contact spring of the sequence changeover contact (b ^I ) remains unoccupied].

On the hold-and-busy line with the connection (hbl), in each separate control box (BK) [in the case of the telephones / subscribers], a [busy] document lamp (BL) is connected in each case,
which is installed in the 2.Lungungaste (2.LT).

Two further normally open contacts (2lr ^{III + IV} ) of the 2nd line relay (2LR) connect [slightly delayed, according to the sequence = changeover contacts (2lr ^{I + II} ) - so that they can not make a connection to the II line via this!] in each case the associated own telephone line with a common call line (CRL) to which a common call relay (GRR) is connected via / with a call capacitor (C3).

With two working contacts (grr ^{I + II} ) of the common Ruf = relay (GRR) an AC voltage to another, third, high-impedance relay coil of the slip relay (B) is laid [so that a ripple (in Rufrythmus) on the common phone line superimposed - to signal a call on its own telephone line].

The supplementary circuit of the published patent application DE 199 40 801 A1 which is also marked with (EGS), is needed for every 2 subscribers and is switched in each case between the dialing system and the extension circuit (ERWS).

The local development W5.)
"Shutting down the wrong call"
[Switching off the 2nd telephone when calling the 1st party with a (r1 ^III ) contact and
Switching off the 1st telephone when calling the 2nd party with a (r2 ^III ) contact]
is to be used!

From you also get the common control line 2 (G2), at which the 2.Teilanansteuerungsanzeigelamp (2TA) in each separate control box (BK) [at the telephones / subscribers] connected.

The Power will be shared for the supplement = circuit (EGS) and the extension circuit (ERWS) used and has a corresponding performance. It also has an AC output for the Relay relay (B), as ripple voltage.

The Examples of the invention: B1.), B2.), B3.) Now follow with reference to Drawings and the table.

there the drawings show the following:

1 Extended supplementary circuit (block diagram)

1a Brief explanation of a symbol: ⌽ off 1

2 Belegrelais (B) and others all-pole, with unipolar continuation, since the continuation is also unipolar; technically, the relay relay is located between the dialer and the 2nd line relay (2LR) of the first subscriber.

The table has the following content:
The explanation of reference numerals used in the drawings, etc.
These are the names of the assemblies, components or parts of components [eg: relay contacts]; or
these are the names of the connections.

In front Examples B1.), B2.) and B3.) there is a small introduction: B.G.) Basic.

B.G.) Basics:

The Participants must into the procedure under = and the telephone directory be provided with instructions accordingly.

• – das heißt, die Klammern sind einfach wegzudenken, kann sie einstellig sein, ist sie möglichst eine "2"
• – das heißt, die Klammern mit der Sieben (7) ist einfach wegzudenken!].

The telephone numbers of the 2nd parties all begin with "(7) 2" - the key number for relay control
[She was from DE 199 40 801 A1 accepted; if she has to be double-digit she is "72"

• - that is, the parentheses are easy to imagine, it can be single-digit, it is possible a "2"
• - that is, the parentheses with the seven (7) is simply not thinkable!].

B1.) A subscriber wants to dial the second subscriber of his [own] technical telephone line, for example: subscriber "3" wants subscriber "(7) 23" ..., drawings used 1 - 2a , which is the most important drawing 1 :

Of the Participant "3" lifts his handset and looks at the 2nd line button (2.LT) of its control box (BK) [standing next to his phone] in which the associated [Busy] Voucher Lamp (BL) is installed. This does not light up, that means the one, only, common Telephone = line (II.Leitung) is free!

Then he presses the 2nd line button (2.LT) of his control box (BK) and his 2nd line relay (2LR) picks up: 2 : Plus potential (+) the follow-up change-over contact (b ^I ) of the relay relay (B), via its common center contact = spring, the inner normally closed contact spring, the connection (ak ') at which the control chain [of the control lines - 2a ] is connected in series with all 2.Lungungasten (2.LT), the connection (ak ') of the control box (BK), the working contact of the actuated 2.Lungungaste (2.LT), the connection (2LR), the relay coil of its 2.Leitungsrelais (2LR) and the minus potential (-).

The Relay picks up and presses his contacts.

The two normally-open contacts (2lr ^{III + IV} ) of the 2nd line relay (2LR) connect [slightly delayed]
the own telephone line with the common call line (GRL), to which the common call relay (GRR) is connected via / with a call capacitor (C3) [- section B2.]].

The follow-up switching contacts (2lr ^{I + II} ) [which are pressed first] switch and disconnect the telephone from its own telephone line and switch it to the one, single, common telephone line (II. Line). It is preceded = set that the dialer can still establish a call connection and they therefore sends the dial tone to the phone. In addition, the relay relay (B) picks up because it is in the a / b line and flows through the telephone loop current [ 2 ]. Its sequence switching contact (b ^I ) is actuated and the positive potential (+) now passes through the follower switch contact (b ^I ) via its common center contact spring; the working contact spring for connection (hbl). From the port (hbl) it goes [ 2a ] via the control line to the holding contact (2lr ^V ) and then to the relay coil of the 2nd line relay (2LR) and to the negative potential (-).

The relay remains energized and will not fall off if the follow-up changeover contact (b ^I ) is moved because it switches without interruption!

From the terminal (hbl), it also goes to the [busy] document lamp (BL) installed in the 2nd line button (2.LT) of the control box (BK) [ 2a ] and at the same time at the minus potential (-). She lights up.

From the port (hbl) it also goes via the control line to all other [busy] slip lamps (BL) in all control boxes (BK) [see: 2a several times + 1 ], so that all of them too light up.

Now the code "(7) 2" is selected for the relay control of the dialer [part of the telephone number of the 2nd subscriber!]. The change-over relay (UM) is activated and thus a plus potential (+) arrives via the common control line 2 (G2) [- see DE 199 40 801 A1 - ≙] - d. Supplementary Circuit (EGS) - [ 1 ] and from there via the control line [ 2a ], Connection (2TA), to all 2nd slave control lamps (2TA) in all control boxes (BK), which are simultaneously at the minus potential (-), so that they all light up. At this he is = know that now the second participant can be selected.

Now the 2.Leitungstaste (2.LT) is pressed again while the listener hung up / the handset [um] switch pressed, so that the connection to the relay selection is terminated [see DE 199 40 801 A1 Although the relay relay (B) drops out briefly, however, since the second line key (2.LT) is pressed, the second line relay (2LR) remains energized [circuit - see at the first key press], and all [occupied ] proof lamps (BL).

Becomes the telephone loop is closed again [receiver lifted again / receiver fork released again) pulls in the telephone line (II.Leitung) recirculating relay (B) and all [Busy] Voucher lamps (BL) lights up again and the 2nd line relay (2LR) stops again [- like already the first time -].

After re-lighting d. [Busy] Voucher Lamp (BL) can be dialed the "remaining" phone number "(.). 3" and the connection will be to the subscriber "(7) 23" via the still free technical telephone line "3" and above the auto = changeover switch (AWADO) [- see DE 199 40 801 A1 ] and the non-actuated follow-up switching contacts (2lr ^{I + II} ) of the unactuated second line relay (2LR) of the subscriber "(7) 23" to the telephone [ 1 + 1a ].

B2.) A subscriber [eg: "3"] wants to set up a telephone connection, but the other subscriber [eg: "(7) 23"] of his [own] technical telephone line has already occupied it: drawings used 1 - 2a , especially 1 :

Of the Participant, for example: "3", lifts his handset and do not hear Dial tone [- because the other participant, for example: "(7) 23", the technical Telephone line has occupied and the automatic changeover switch (AWADO) the Telephone line switched to the other subscriber.

Now he sees the 2nd line button (2.LT) of his control box (BK) [standing next to his phone] in which the associated [Busy] Voucher Lamp (BL) is installed. This does not light up, that is: the common telephone line (II.Leitung) is free!

Now can he - according to section: B1.) - one Establish a telephone connection, with the single exception, not to the other participant [e.g.:"(7)23 "] of the technical Telephone line!

there It does not matter if it's a second participant or a first participant is.

Another process can occur:
The other subscriber, eg: "(7) 23", the technical telephone line terminates his telephone conversation and the technical telephone line with the automatic changeover switch (AWADO) is released.

Then a call is made for the participant, for example: "3", above the common telephone line (II.Leitung) has a telephone connection.

This call is not lost, but goes [see: 1a ]
from its own telephone line via the two working contacts (2lr ^{III + IV} ) of the operated second line relay (2LR) to the common call line (GRL) to which the common call relay (GRR) - via / with a call capacitor (C3) - arrives = closed is [ 2 ]. The common call relay (GRR) picks up in the pending rhythm and places with its two working contacts (grr ^{I + II} ) - in the pending rhythm - an alternating voltage on the third, high-impedance coil of the relay relay (B) with the connections (5 + 6). The AC voltage is then superimposed on the common telephone line (II.Leitung) using the other coils of the relay relay (B).

Based the buzzer, the participant recognizes, for example: "3", the existence Call on his own phone line is present. Now he can do that existing telephone conversation over the terminate and receive the common telephone line (II.Leitung) through listeners, after dropping the relay contacts, the call directly on his phone and can accept it.

B3.) Two subscribers [eg: "3" + "4"] want to set up a telephone connection simultaneously via the one, single, common telephone line (II. Line), used drawings 1 - 2a , especially 2a :

If both push the 2nd line button (2.LT) on the control box (BK) at the same time, the 2nd line relay (2LR) of the station picks up "3"
[see the beginning of section: B1.]].

Since all 2nd line buttons (2nd LT) are connected in series to the control line [of the control line] - 2a several times + 1 ] are connected, it says:
at the first terminal (ak ') [ 2 + then 2a multiple times!]
the terminal (ak ') is connected to the second line key (2.LT) of the subscriber "3" and to the quiescent contact spring of which is the terminal (ak ") at which
the terminal (ak ') is connected to the second line key (2.LT) of the subscriber "(7) 23" and to the quiescent contact spring of which is the terminal (ak ") at which
the terminal (ak ') is connected to the second line key (2.LT) of the subscriber "4" and to the quiescent contact spring of which is the terminal (ak ") at which
the connection (ak ') is connected to the second line key (2.LT) of the subscriber "(7) 24" and to the quiescent contact spring of which is the connection (ak ") at which .... etc!

However, since the second line key (2.LT) of the subscriber "3" is actuated, the incoming positive potential at the terminal (ak ') passes over the normally open contact of the actuated 2.LungungTaste (2.LT) to the terminal (2LR) and thus to the relay coil of the 2nd line relay (2LR); Thus lies at the rest contact spring and thus at the terminal (ak '') no plus potential, via the Ansteuerkette [the control line] - 2a several times + 1 + 1a ] is forwarded. A 2.Leitungsrelais (2LR) of another participant, eg: "4", thus can not wear! Only the foremost participant has success!

further development:

W1.)

The connection with the publication DE 197 36 827 A1 is conceivable / meaningful, because then can the local call station (RS) and other [structural] in the control box (BK) are taken over.

W2.)

meaningful would it be, the whole control lines over to run a data bus.

Then is the number of needed Lead wires from the extended supplementary circuit to the control box (BK) low and uniform.

W3.)

A major advancement is the use of two smaller initial dialers with [at least] one trunk, but no cross-connect wires - each fitted according to the 1st solution. Here can / is:
the one [reserved] common telephone line (II.Leitung) - the first dialing system - [continued] as one
single, further [reserved] common telephone line (III.Leitung)
for each participant of the other first-dialing system - with the help of a 3.Leitungstasten (3.LT) - be made available;
this is done in the same way in the opposite direction.

Each participant has a 3rd line button (3.LT) with a contact in the / a separate control box (BK)
[which also contains the 2nd slave control lamp (2TA) and, if necessary, the second cable key (2.LT) {- with the second line relay (2LR) connected to it)},
on d. one in the extension circuit (ERWS)
[- the one behind the supplementary circuit (EGS) ≙ DE 199 40 801 A1 connected -]
associated 3rd line relay (3LR) is connected;
its contacts [eg: follow-up switching contacts (3lr ^{I + II} )] are like the contacts of the 2nd line relay (2LR) switched, only just on
connected to a single [reserved for the procedure], common telephone line (III. line) and between its own telephone line / behind the supplementary circuit (EGS) and
before the follow-up changeover contacts (2lr ^{I + II} ) of the 2nd line relay (2LR), or [if not available] the telephone!

• – der eigenen Erst-Wählanlage,
• – sondern auch das der anderen Erst-Wählanlage,
• – also die Umschaltrelais(UM) beider Erst-Wählanlagen ansteuert, sodaß eine Anwahl eines zweiten Teilnehmers der anderen Erst-Wähl= anlage möglich ist.

When selecting the key number for the relay control [eg: "(7) 2"], not only the change-over relay (UM) is activated with the help of the relay contact (R-contact)

• - your own first-time dialer,
• - but also that of the other first-dialer,
• - So the changeover relay (UM) controls both first-dial systems, so that a selection of a second party of the other first-choice = system is possible.

This is achieved by
the change-over relays (UM) of both first-time dialers
and
the relay contacts (R-contact) of both primary selectors are switched in parallel by [one bridge].

This bridge is omitted if the forwarding of a single [reserved for the process] common telephone line from the one-dialer to the other first-dialer [III.Leitung]
just
to a single telephone and an [extra] alarm clock (W), nearby / by telephone
[eg: in the study at home]
or
only two telephones with an alarm clock switch (WUM) with one [extra] alarm clock (W) nearby / at the telephone
[eg: on the boss phone and on the secretary phone in operation]
he follows!

W4.)

• – gemäß/siehe W3.) –
• – mit voller Erreichbarkeit für alle Telefone/Teilnehmer zur III.Leitung mit Hilfe der 3.Leitungsstaste(3.LT) läßt sich für die Vermittlungsperson – bei beiden Erst-Wählanlagen, bei dessen Telefon, ein besonderer Bedienungskasten(BK') anschließen, indem noch mehr Funkionen eingebaut werden: z.B.:
• – Beleglampen der technischen Telefonleitungen beider Wählanlagen oder zumindenstens der jeweils anderen Wählanlage,
• – zusätzliche 3.Leitungsstasten(3.LT) aller Telefone/Teilnehmer, die parallel zu jenen einzelnen der Teilnehmer der anderen Erst-Wählanlage geschaltet sind und mit der entsprechenden Rufnummer beschriftet sind.

In the interconnection of two Erst-Wählanlagen

• - according to / see W3.) -
• - With full accessibility for all phones / participants to III.Leitung using the 3.Leitungsstaste (3.LT) can be for the operator - at both Erst-dialing systems, connected to the telephone, a special control box (BK ') by even more functions are installed: eg:
• - document lamps of the technical telephone lines of both dialers or at least the other dialer,
• - Additional 3.Leitungsstasten (3.LT) of all phones / subscribers, which are connected in parallel to those individual participants of the other first-dialing system and are labeled with the corresponding phone number.

• – ein ankommendes Amtsgespräch der einen Erst-Wählanlage zu einem Telefon/Teilnehmer der anderen Erst-Wählan= lage – über die technische Rufnummer der eigenen II.Leitung z.B. "8", die dann dort die III.Leitung ist, weiter zuvermitteln.

With the help of this 3.Leitungsstaste (3.LT), the operator of the first-dialing system can make a Vorein = position at a telephone / subscriber of the other first-dialing, for example

• - An incoming trunk call of a first-dialing system to a telephone / subscriber to the other Erst Wählan = location - on the technical number of your own II.Leitung eg "8", which is then the III.Leitung there, onward.

Is d. desired telephone / subscriber is busy, because he has just a telephone connection with the help of 2.Leitungs = button (2.LT),
becomes a call - as already described -
with the help of the common call relay (GRR) II.Leitung u. the high-impedance relay coil of the relay relay (B), at which an alternating voltage is applied in the Rufrythmus transmitted - as a buzzer.

sets now the participant briefly the listener on, he has the call from the other first-dialing system!

So that the existing telephone connection is not disconnected with the help of the 2nd line key (2.LT) during the presetting, the following sequence must be observed during the setup:
technical telephone line - supplementary circuit (EGS) with the automatic changeover switch (AWADO) - then only the relay contacts of 3.Leitungsrelais (3LR) - and then only the relay contacts of the 2nd line relay (2LR) - and then behind the phone!

Sch.) Conclusion:

From the above-described [Examples: B1.) -B3.)] Shows that not only the other participants in the common technical telephone line over
the one, single, common telephone line (II.Leitung) can be selected,
but also a [important] conversation is possible if the other participant of the common technical telephone line - this has already occupied!
