Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interrupt connection method from a toll operator in order to confirm the number of a calling subscriber from a toll unit in a digital exchange. This invention relates to the interrupt connection method of a multiplex exchange.

A conventional confirmation interrupt method for confirming a subscriber number from a toll phone is shown in FIG.

In FIG. 1, 100 is a subscriber, 101 is a space division channel switch, 102 is a hold recall connection trunk, and 103
104 is a long-distance stand, 105 is an operator, and 106 is a sound source.
0 and space division channel switch 101 are subscriber line 110
The hold recall connection trunk 102 and the call path switch 101 are connected by a trunk line 111, the interrupt connection trunk 103 and the call path switch 101 are connected by an interrupt link 112, and the hold recall connection trunk 104 and the call path switch 101 are connected by an interrupt link 112. connection trunk 10
2. Interrupt connection trunk 103 is trunk line 1, respectively.
13 and 114, and furthermore, the toll stand 104 is connected to an operator 105 and a sound source 106.

Further, 120 and 121 are space division channel switch 1.
This is a call switch created by closing the switch in 01, and 122 is an interrupt call switch path.

When subscriber 100 calls to toll station 104, the corresponding toll station 1
The hold recall connection trunk 102 is seized to connect to the subscriber line 110 on the ingress side of the space division channel switch 101, and a path of 120° 121 is formed by closing the switch of the space division channel switch 101. and the outgoing trunk line 111 to create a call path (100-110-120-121111-1) between the subscriber 100 and the operator 105.
02-113-104-105) and can make a call.

Here, the operator 105 of the toll station 104 is the calling subscriber 1.
After receiving the subscriber number from 00, the operator 105 needs to determine whether the subscriber number is correct.

In that case, the operator 105 dials the subscriber number of the calling subscriber 100 from the toll machine 104.

When the caller connection trunk 103 receives the dial, that is, the calling subscriber number from the toll station 104, the corresponding call path, that is, the path to which the subscriber 100 is currently connected, is activated by a control unit (not shown) in software. 121 and forms an interrupt call path 122 for interrupting the call path, and the subscriber 100, operator 105, and sound source 106 are simultaneously connected.

Therefore, the sound of the sound source 106 is transmitted to the interrupt ring 112 and the path 122.
It is sent to the operator 105 via 121.

That is, by listening to the sound from the sound source 106, the operator 105 can determine that the originating subscriber number is correct.

(The route for simultaneous connection is 106-104-114-10.
3-112-122-121-111102-113-
104-105) In the case of a space division channel switch, an interrupt switch is provided to perform interrupt connections so that multiple connections can be made spatially using the switch.

However, in a digital exchange, that is, an exchange having a time-division channel switch, when attempting to provide the same service as above, it is known that three
It is not possible to connect the right side at the same time, and conventionally such interrupt connections have not been made.

The object of the present invention is to provide an interrupt connection system that enables interrupt connection from a toll station in the same way as a space division communication path when the communication path device of an exchange becomes a time division communication path, and will be described in detail below.

FIG. 2 shows an embodiment of the present invention, in which 200 is a subscriber;
01 is a time-division channel switch, which, as is well known, includes a time shift circuit that converts a time slot assigned to a time-division channel highway into an arbitrary time slot;
It consists of a gate circuit for connecting to any time-sharing channel highway at any time.

202 is a holding recall connection trunk, 203 is an interruption person connection trunk, 204 is a toll machine, 205 is an operator, 2
06 is a sound source, and 207 is a digital conference trunk.

The toll stand 204 is connected to the hold recall connection trunk 202 and the interrupt contact trunk 203 via trunk lines 213 and 214, respectively, and is also connected to the operator 205 and the sound source 206, as in the conventional example. is similar to , but the subscriber 200 connects to the toll machine 204 and the toll machine 2
04, the output signals of the subscriber 200, the hold recall connection trunk 202, the interrupt user connection trunk 203, and the digital conference trunk 207, respectively. It is configured to be connected to the time division communication path switch 201 through time slots assigned to each of the time division communication path highways 210, 211, 212° 215.

Although not shown, the digital conference trunk 207 generally has three or more connection terminals, and at least three or more time slots are assigned to the trunk in the time-division communication route highway 215 in which the terminals are accommodated. It is being

Furthermore, the time slots to which the hold recall connection trunk 202, the interrupter connection trunk 203, and the output signal of the subscriber 200 are connected are assigned to the digital conference trunk 207 through the time division channel switch 201.
connected separately to one or more timeslots.

Furthermore, in the digital conference trunk 207, the signal outputted to any terminal is configured to be a signal that is a composite of significant signals among the signals inputted to other terminals. It is a well-known technology to be able to make phone calls.

Digital conference trunk 207 configured as above
The digital conference trunk 207 is used in conjunction with the hold recall connection trunk 202 to provide an interrupt connection using the hold recall connection trunk 202 .

That is, when subscriber 200 makes a call to toll station 204, hold recall connection trunk 202 and digital conference trunk 20 are connected.
7 through the time division channel switch 201 at the same time.

In this case, subscriber 200 is connected to digital conference trunk 207.
The held call connection trunk 202 is connected to the second terminal of the digital conference trunk 207 .

Figure 2 shows the connection between highways 210 and 211.
．． It is symbolically shown in the form that 215 is once concentrated.

This connection forms a communication path between subscriber 200 and operator 205.

That is, the connection path is 200-210215-207-2
15-211-202213-204-205.

When a dial is made from the toll station 204 to confirm the calling subscriber number, the interrupt connection trunk 203 receives the dial, and the subscriber station 200 is connected by the operation of a control unit (not shown) by software. The third digital conference trunk 207 of the trunk 207 is searched.
The interrupt service connection trunk 203 is connected to the terminal of the terminal via the time division communication path switch 201.

That is, the communication channel 212 is connected to the third terminal of the digital conference trunk 207.

In any of the above cases, the meaning of "connecting to a terminal" is to connect in a time-sharing manner to the time slot assigned to that terminal, as described above.

By making such a connection, the subscriber 200, operator 205, and sound source 206 are permanently connected in the digital conference trunk 207, and the sound source 206 is connected to the interrupter connection trunk 203 and the digital conference trunk. 207, the operator 205 can hear and confirm the calling subscriber 200 via the hold recall connection trunk 202.

That is, an interruption path is formed in which the sound source 206 interrupts the communication path between the subscriber 200 and the operator 205.

As explained above, in a digital exchange equipped with a time-division channel switch, by using a digital conference trunk for interrupt connection for confirming subscriber numbers from a toll machine, a new device for interrupt connection can be created. The above-mentioned interrupt connection can be realized without preparing a software, software processing is simple, and operator operations can be performed in the same way as before.
