Next, the present invention will be described with reference to the drawings.

FIG. 1 is a flow chart for explaining the operation of one embodiment of the subscriber terminal designated incoming call receiving system of the present invention, and FIG. 2 (a).
FIG. 2 is a system block diagram of a stored program controlled exchange system to which an embodiment of the present invention is applied, and FIG. 2B is a diagram showing an example of a subscriber data structure in a main storage device in FIG.

Referring to FIG. 2A, the stored program controlled switching system according to the present application includes a stored program controlled switching system (SPCA) 2 and a stored program controlled switching system connected to the SPCA 2 and a trunk line 6. (SP
CB) 3.

The SPCA 2 accommodates a calling terminal (CLG) 1 and called terminals (CLD) 41 and 42, and a SPCB 3
Accommodates a CLD 51.

CLG1 is a general telephone, and CLD41
And CLD42 are a general telephone set in the office 4 and a telephone attached to the facsimile machine.
Reference numeral 51 denotes a general telephone set at home 5.

The CLDs 41, 42, and 51 are 1
It belongs to one group, and this group is given a single subscriber number N and a subscriber class for controlling the CLDs 41, 42 and 51 as one group.

A main storage device (not shown) in the SPCA 2 stores subscriber data of the called subscriber (including, for example, the terminal number translation list 20 and the terminal number list n21 shown in FIG. 2B). .

In FIG. 2B, the terminal number translation list 20 is linked with the terminal number list for each subscriber number. The terminal number translation list 20 is searched by the subscriber number, and the terminal number list number is obtained. obtain. In the figure, a terminal number list n21 of the subscriber number N is obtained.

In the terminal number list n21, selection codes "0", "1",
The telephone numbers of the CLDs 41, 42, 51 corresponding to "2" are stored.

Next, the operation of one embodiment of the present invention will be described with reference to FIG.

When a caller makes a call from CLG1 (step S1), SPCA2 sends a dial tone from a call register (not shown) as is generally known (S2).

When the caller hears this dial tone and dials the subscriber number N, the call register receives the call in SPCA2, and the called subscriber sets a plurality of terminals to one from the subscriber class of the subscriber number N. Recognizing that the subscriber is a group-owned subscriber, the second dial tone is transmitted, and the caller is prompted to dial a known selection code of the called terminal (S4).

If the selection code of the called terminal is not known, a message (for example, "0" for a telephone call to an office or facsimile transmission) is used instead of the second dial tone in S4. For example, "1" may be dialed, and "2" for a home call. ").

When the selection code of the called terminal is received from the CLG 1 (YES in S5), in SPCA2, the central processing unit (not shown) searches the terminal number translation list 20 with the subscriber number N and searches the terminal number list n21. And the terminal number list n21 is changed to the selection codes “0”, “1”, “2”.
(S6) to extract and translate the terminal number of the designated called terminal (S7).

When the called terminal is accommodated in the own station based on the terminal number translated in S7 (YES in S8), the central processing unit stores the CLG1 in the office 4 by a generally known method. (S9) In-station connection processing is performed for (CLD41 or CLD42 according to the selection code).

When the called terminal is accommodated in another station (NO in S8), the central processing unit performs an outgoing connection process to the trunk line 6 (S10), and the call from the CLG1 is SPCA.
2, connected to the called terminal (CLD 51) at home 5 via the trunk line 6 and the SPCB 3.

In S4, timing monitoring is started from the time when the second dial tone or message is sent out. If the selection code of the called terminal is not received from the caller before the time-out (NO in S5), registration is made in advance. A so-called representative connection process based on a given representative terminal number, a call transfer process to a registered predetermined terminal, or a call rejection may be performed (S11).

The representative terminal number and the call transfer destination terminal number are easily registered by applying a generally known technique.

As described above, in this embodiment, when the caller dials the selection code for designating the called terminal following the called subscriber number N, the CLG 1 makes the called terminal CLD
It is connected to a desired terminal among 41, 42 and 51.
