T: set automatically and decide number, calling is arranged to notify the user.

The present invention can add the priority level sign indicating number on each telephone number of phone directory, be used to handle relative, close friend's etc. calling, in case can send special ring after the checking, or in default special time, the calling that only has priority level can start ring.Security password comprises that personal visit sign indicating number and remote control access code also imported by the user in addition, can be the combination of long number or letter and numeral, when the user leaves, has only addressable its phone of people of user oneself or user's appointment and (" locked " do not mean and can not throw phone into by locked, the remote control access code refers to that the user can obtain with phone at a distance or eliminates the information of having stored or reset, and other should be imported by calling order by the user entirely one by one as the phone of pager, radio telephone and appointment etc.).

The present invention has adopted the voice record circuit of one group of fully digitalization, comprise: microcomputer 111, the selection that CPU2, voicebank device 113, VODER 120 and recording characteristic selector 116, microcomputer 111 CPU2 press selector 116 receives operational order from another microcomputer 110, and to write down, to check and remove following message: output message, individual's message and speaker leave a message.Typical output message as: " your this phone of on; this is a computerized telephone system; please import your telephone number; " so that for you transfer rapidly, " sorry; that we can't receive calls immediately, please stay your your name, telephone number and message behind Bi Bisheng ", the user also can stay individual's message.

The system control switch that is connected with outside line is used for select operating mode, and telephone set 100 can use separately also can piece together with elementary cell 101 1 and use, and this is that a kind of logic switch is used for the correlation between definite circuit of the present invention and telephone set.When switch is allocated to independent use phone, then bell signal will directly be transported to the ringing circuit of phone 100 by switch 126, comprise ringing-current detector 107, ringing current generator 108 and loud speaker 109, the user can converse by off-hook 106, also direct off-hook 106 of user is outwards made a phone call by keyboard 105 input telephone numbers in addition.

When telephone set and device of the present invention connect into system and use, the ringing signal of input can not start ringing current generator 122, incoming call is replied by microcomputer 110 CPU1, sending the first output message earlier requires the other side to import its telephone number, microcomputer 110 order microcomputers 111 take out the signal of being pre-recorded from speech memory 113, reach VODER 120 and produce the voice of reserving.

The speaker is by its telephone number of indication input, and this number is received by DTMF receiving circuit 112, is stored in the working area of memory 114 again.The present invention is preset with the abundant time and sent its telephone number as 5 seconds for the other side.And DTMF receiving circuit 112 is when the signal that receives from the calling party, and internal clocking is promptly reset next Preset Time and used as receiving next time input signal.The operation of reseting of this clock is carried out repeatedly, does not receive input signal again after Preset Time is ended, when perhaps detecting the input signal that " # " or " * " symbol is arranged in the existing phone till.

After speaker's telephone number is received, promptly demonstrate this telephone number on the display panel 119, of the present inventionly drill that translator program will be imported and temporary telephone number is weaved into the sign indicating number of deriving.Because if 7 phone number are all derived use the processing time that then will increase demonstration validation, therefore afterbody 4 figure places in desirable 7 figure places make to derive sign indicating number.Speaker in the working area derive sign indicating number with pre-record in the confirmation code comparison of deriving of the telephone number of memory 114, because the telephone number of general user's storage is in 100, and the time relatively only needs several seconds zero point, so the speaker is subtle relatively works to this.

If the caller can't intactly import its phone number within the predetermined time, what write down in the working area will be incomplete sign indicating number, in general be judged to wrong incoming call less than Entering Number of 7 figure places.If speaker's refusal is imported phone number within the predetermined time, in the typing working area also is incorrect sign indicating number, promptly skips comparison program and sends backward signalling once measuring incorrect number input.To send second output message behind the backward signalling of preset times, speaker's the sound that stays will be digitized and be stored in the voicebank device 113.The present invention is provided with a counter (not drawing among the figure), be used to calculate the speaker the number of times of leaving word, calculate total degree and be shown in display panel 119, LED lamp flicker reminds the user that speaker's message is arranged.

When the sign indicating number of deriving of input telephone number is more consistent with the sign indicating number of deriving of telephone number in the phone directory, produce backward signalling and reach the calling party by telephone wire, this backward signalling also will trigger ringing current generator 122, send telephone bell by loud speaker 123, represent that this is the phone that once can connect, 106 conversations of user's off-hook.

The present invention also can be designed to number of rings fixed number when implementing, jingle bell six times before calling changes storage circuit over to for example, and user's off-hook conversation immediately, the user during off-hook, does not send the message that request the other side leaves a message yet after default number of rings.

If what compare is that what ringing current generator 122 sent is special the tinkle of bells, can cooperate the application of priority level sign indicating number by programmable timer when deriving sign indicating number and unanimity.Just can throw phone into as the user who only has the priority level sign indicating number up to 6 times of morning next day in evening 10.

All kinds of message position occupied can be referring to Figure 10 in the voicebank device 113, A, B, C are followed successively by first, second, third output message from left to right among the figure, D is individual's message P.M., E keeps the temporary telephone number to first speaker, this number is digitized processing, will carry out phonetic synthesis during application, F is first speaker's message district (can or break or forget to Enter Number and form the clear area in E, F position because of no speaker).G, H, I ... supply second, third respectively ... temporary telephone number of speaker and storage message.

Since the record of message with send all digitlizations, the user can utilize recording characteristic selector 116 and cooperate keyboard 130 to write down, check or eliminate the message of any record.As operate output message key and numeral " 1 " key and can write down first and export and leave a message; Operation display key and n speaker's message just can show corresponding message.Operation upper and lower, left and right key can obtain respectively forward, message backward; The operation cancel key then can be eliminated message.If there is not further operational order, display key automatically shuts down after the default time in the operation.

Memory 114 headphone catalogues, safety code, transfer phone, calling set and wireless telephonic number, these numbers are by position shown in Figure 11 record, and preceding ten telephone numbers can keep to close relative, close friend etc., have the priority level sign indicating number concurrently.Also can adopt speed to dial function,, press by " speed is dialled " function key and press by any one numeral in 0～9 to access the storage portions of relevant position as off-hook 106.The order of microcomputer 110 receiving function keys is taken out desired telephone number and is got phone automatically through dialing generator 117 from 114, show this telephone number on the while 119, and transfer phone, pager phone, radio telephone generally are stored in 114 end.

Transfer notion of the present invention is: in the time will being forwarded to a common phone or radio telephone, the present invention can transfer to the switching number of an appointment automatically, and this switching number takes out from memory 114.When the user uses the designated telephone of being transferred or radio telephone to answer, can hear of short duration message, as " having words to leave you for ", the user can operate and shake control code to listen to message and the telephone number of being write down in the voicebank device, also calling can be forwarded to a pager and use to enlarge.

The present invention can turn-off system control switch 126 when phone 124 power failure, telephone set 100 is separated with elementary cell 101, and telephone set 100 promptly can work independently and is not subjected to the influence of elementary cell 101.
