JPS59105748A - Sound mail mailing display system - Google Patents

Abstract

PURPOSE:To attain satisfactorily the convenience and the reduction of communication loss which are original purpose of the sound mail service and at the same time to facilitates an easy operation for a telephone set which is capable of the sound mail service, by displaying the mailing to the addressed telephone to which the sound mailing is done. CONSTITUTION:When a sound mail access special number is dialed from a TEL1A, the TEL1A can have communication with a sound main deice VMS7 by a communication line consisting of a digital line circuit DLC2A, links (a), (a') and L and an interface circuit INT60. Thus the sound mail given from the TEL1A can be stored to a prescribed address of a magnetic disk device DSK70. When the TEL1A is hooked on after the mailing of sound mail is over, a control part CNT71 transmits a sound mail store end signal to an INT61 and stores it there. A central controller CC4 scans periodically the INT61 and reads out both the sound mail store end signal and the addressed subscriber information (address information of TEL1N). Then the controller CC4 adds 1 to a counter circuit of the TEL1N and controls a DLC2N to display the mailing of sound mail frequency to the TEL1N.

Next, the operation of this embodiment will be explained.

For example, when a station LIA goes off-hook, CC4 periodically scans 1) LC2A, detects call information from the DLC2A, performs a generally known call connection, and performs a call register trunk (not shown). ) becomes ready to receive numerical information from device LIA via NW3. Next, when the previous device zA dials the predetermined voice mail access special number 1X, the NW3 dials the voice mail access special number 1X.
The link between JL02 and the outgoing register trunk is obsolete, and the link between the DLC2A and INT60 ■, ◎

Every time E L I N hears a message,
If the dial link of Y' is performed, the voice mail retrieval operation described above is repeated. Other ejecting subscribers 1'El, IB
The same applies to , IC, ~. If it is necessary to save the voice mail, the voice mail retrieval subscriber dials "Save voice mail eiuz" and can listen to the message in the same manner as the voice mail retrieval operation described above. Since the voice mail retrieval end signal is not set in IN'I'61,
The CC4 does not subtract n from u1'' in the argument circuit, and the display of the number of posts by the retrieving subscriber remains unchanged.

Note that in this embodiment, the voice mail access special number ``'X
It goes without saying that any numeric code or special code may be predetermined for ``, retrieval special number try'', storage special number tfZn, and posting percentage check ``#'' as long as they are different from each other.

Next, FIG. 2 is a diagram showing an example of the bit configuration of the main memory in the device shown in FIG. 2 in the same figure, the counting circuit section that stores the number of mails for each subscriber location information %ENa, ENb, ~ENo stores information for 1 byte (8 bits) of subscriber addresses, that is, a maximum of 256 emails. The count value of can be stored.

As mentioned above, CC4 (shown in FIG. 1) receives u1''' plus q, .
The argument value of the divider circuit corresponding to the subscriber accommodation location information EN is changed by 1 by subtracting q, etc.
