〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a switchboard pseudo call device according to an embodiment of the present invention, FIG. 2 is a diagram showing an example of a switchboard pseudo circuit in FIG. 1, and FIG. FIG. 3 is a diagram illustrating an example of a process of transmitting and receiving a signal and a received signal.

In FIG. 1, the automatic exchange 1 to be tested includes:
In addition to the small number of switchboards 2, a switchboard pseudo call device 3 is connected via a switchboard control device 4.

Also connected to the automatic exchange 1 is an automatic pseudo call device W5 that operates in cooperation with the switchboard pseudo call device 3.

The switchboard pseudo call device 3 is provided with a plurality of switchboard pseudo circuits 6 each simulating the switching operation of the switchboard 2.

As shown in FIG. 2, each station simulator circuit 6 includes a transmission signal memory 61 as a means for holding various transmission signals transmitted from the switchboard 2 to the switchboard control device 4 by the operator's operation, and a transmission signal memory 61 that is exchanged from the automatic switchboard 1. A received signal memory 62 is provided as means for holding various received signals transmitted via the stand control device 4.

Further, a counting circuit 63 and a time limit circuit 64 are provided as means for sending the held transmission signals to the automatic exchange in a predetermined procedure, that is, in a predetermined order and time interval.

Furthermore, a collation circuit 65 is provided as a means for identifying the received signal transmitted from the automatic exchange and using it as a trigger for transmitting the transmitted signal.

In the initial state, the counting circuit 63 of each pseudo-circuit 6 indicates the starting address (for example, address 0) of the sending signal memory 61 and the receiving signal memo IJ 62, and from the starting address of the sending signal memory 61, the response signal and sending time are calculated. The interval t1 is extracted and stored in the register 66, and is also stored in the received signal memory 6.
It is assumed that the incoming call signal a is extracted from the first address of No. 2 and stored in the register 67.

Next, using FIGS. 1 to 3, we will explain the process of generating a pseudo call load by the switch pseudo call device, taking as an example the case where the switchboard 2 accepts an incoming call and connects it to a desired called subscriber. .

In FIGS. 1 to 3, when the automatic pseudo call device 5 makes a pseudo call and sends out a special number for calling the switchboard 2, the central controller 11 sends a call to each switchboard 2 and the switchboard pseudo call circuit 6. Signal a obtained by adding the assigned machine identification number pn to the machine incoming signal a
1 and transmits it to the switchboard control device 4.

The switchboard controller 4 analyzes the signal a1 transmitted from the central controller 11, and transmits the console incoming signal a to the console pseudo circuit 6 designated by the console identification number pn.

In the stand pseudo circuit 6 , the receiving circuit 68 transmits the stand incoming signal a transmitted from the switchboard control device 4 to the verification circuit 65 . The collation circuit 65 collates the machine incoming signal a transmitted from the receiving circuit 68 and the machine incoming signal a stored in the register 67, and activates the timer circuit 64 if the two match. The activated time limit circuit 64 starts measuring time, and when the time interval t1 stored in the register 66 has elapsed, the response signal stored in the register 66 is transmitted to the transmitting circuit 69.
At the same time, the counting circuit 63 is advanced by one step. The transmitting circuit 69 sends the transmitted response signal to the switchboard control unit 4. When the counting circuit 63 advances one step, the call class designation signal d and the sending time interval t2 are extracted from the next address in the transmitted signal memory 61 and stored in the register 66, and the return signal is extracted from the next address in the received signal memory 62. C is extracted and stored in register 67.

The switchboard control device 4 creates a signal b" by adding a switchboard identification number pn to the response signal transmitted from the switchboard pseudo-circuit 6, and
The information is transmitted to the central control device 11.

The central control device 11 analyzes the signal bl transmitted from the switchboard control device 4, and returns a console response signal to the automatic pseudo call device 5, and also sends a response signal C indicating that the console response signal has been received. A signal C° with a stand identification number pn added thereto is created and transmitted to the switch stand controller 4.

The switchboard control device 4 analyzes the signal C1 transmitted from the central control device 11, and transmits a return signal C to the stand pseudo circuit 6 designated by the stand identification number pn.

In the base detection circuit 6, the receiving circuit 68 transmits the return signal C transmitted from the switchboard control device 4 to the collation circuit 65. The collation circuit 65 collates the return signal C transmitted from the receiving circuit 68 and the return signal C stored in the register 67, and activates the timer circuit 65 if the two match.

The activated timer circuit 65 starts timing, and the register 66
When the time interval t2 stored in
9 and advances the counting circuit 63 by one step. The transmitting circuit 69 sends the transmitted call class designation signal d to the switchboard controller 4. When the counting circuit 63 advances by one step,
The incoming telephone number designation signal f and the sending time interval t3 are extracted from the next address of the transmission signal memory 61 and stored in the register 66.
The return signal e is extracted from the next address in the received signal memory 62 and stored in the register 67.

The switchboard control device 4 creates a signal d' by adding a platform identification number pn to the call class designation signal d transmitted from the platform pseudo circuit 6, and transmits it to the central control device 11.

The central controller 11 analyzes the signal d" transmitted to the switchboard controller 4, and creates a signal e" in which a return signal e indicating confirmation of reception of the call class designation signal d is appended with a platform identification number pn. and transmits it to the switchboard control device 4.

The switchboard control device 4 analyzes the signal e' transmitted from the central control device 11, and transmits the return signal e to the platform pseudo circuit 6 designated by the platform identification number pn.

Thereafter, in the same manner, after confirming that the return signals e, g, and i have been returned from the switchboard controller 4 using the return signals e, g, and i sequentially extracted from the reception signal memory 62, the stand pseudo-circuit 6 transmits the signals. The incoming telephone number designation signal f, division signal and paging signal j sequentially extracted from the signal memory 61 are sent after predetermined time intervals t3, t4 and t5, which are simultaneously extracted from the transmitted signal memory 61, are sent out to control the switchboard. It is transmitted to the central control unit 11 via the device 4.

The central control device 11 analyzes the signal j" transmitted from the switchboard control bag W4, transmits a return signal k to the stand pseudo circuit 6 via the switchboard control device 4, and also transmits a return signal k to the switchboard pseudo circuit 6 by the incoming telephone number designation signal f. The calling signal is transmitted to the designated automatic pseudo call device 5.

The automatic pseudo call device 5, which has received the paging signal, returns a response signal after a predetermined time interval.

Thereafter, in the same manner, the stand pseudo-circuit 6 receives the return signals ksn, .
・After confirmation by r, three-way call signal m, monitor signal 0, . After t9 has elapsed, it is sent out and transmitted to the central control device 11 via the switchboard control device 4,
When receiving an incoming call and connecting to a desired terminating subscriber, the exchange 2 completes a series of transmission and reception of signals, and is again set to the initial state.

The automatic pseudo call device 5 sequentially transmits a call disconnection signal and a call disconnection signal to the central controller 11 from the pseudo calling subscriber who originally sent the special number and the pseudo called subscriber who returned the response signal, and then again. Repeat the above process.

As is clear from the above description, according to the present embodiment, when the switchboard 2 accepts an incoming call and connects it to a desired called subscriber, the base station reconnaissance circuit 6 transmits various transmitted signals and received signals in the same process. Transmission and reception will take place with the switchboard control device 4, and a load similar to that of the operator of the switchboard 2 will be automatically applied to the automatic switchboard 1.

Note that FIGS. 1 to 3 are only one embodiment of the present invention, and for example, the types of transmitted signals and received signals stored in advance in the transmitted signal memory 61 and the received signal memory 62 may be different from those shown in the figures. There are no limitations, and many other variations can be considered, such as a control signal for a lamp provided on the switchboard, a buzzer, or a display signal to a display device, but the type added to the switchboard pseudo call device 3 Any connection process can be simulated by arbitrarily storing data from the writer device 7, but the effects of the present invention remain the same in either case.
