N subscriber line drop-in lines l 11 to l no from each subscriber circuit are made into multiple sets within each subscriber circuit group, and are connected to the simultaneous talkie sending unit TKYU. The simultaneous talkie sending unit TKYU is composed of talkie sending circuits TKY1-TKYM corresponding to each of the subscriber circuit groups SCG1-SCGM, and a talkie control circuit TKYCONT for controlling the talkie sending circuits TKY1-TKYM. Each of the talkie sending circuits TKY1 to TKYM has the same configuration, and the detailed circuit configuration is shown in FIG. In the same figure, TKR is the talkie control circuit
Relays controlled by TKYCONT, tk 0 to tk 2 are contacts of relay TKR, and D is a Zener diode, which, if the telephone is a PB telephone, supplies the potential necessary to form a loop during off-hook. R indicates a limiting resistance, and E indicates a power source. When the exchange is normal, relay TKR is inactive,
Subscriber drop-in lines l11 to lno from each subscriber circuit group SCG1 to SCGM are connected to a test device (not shown) via a contact point tk1 . The other contact of the contact tk 1 is connected to the transformer T of the talkie sound source via the Zener diode D and the contact tk 0 . At this time, the talkie transmitting circuits TY1 to TKYM are connected to the transformer T in a duplex manner.

In conventional time-division switching equipment, each talkie sending circuit TKY1 to TKYU of the simultaneous talkie sending unit TKYU
In TKYM, during simultaneous talkie transmission, current flows steadily through the route of power supply E → control resistor R → Zener diode D → transformer T, so Zener diode D and limiting resistor R are connected to heat sinks or large resistors. Measures are taken to prevent heat generation, such as using equipment. Then, there are M talkie sending circuits that require measures against heat generation.
Since TKY1 to TKYM are mounted in one place on one rack, each circuit has to be large in order to meet the thermal conditions, which poses a problem in miniaturizing the unit. Furthermore, the subscriber circuit groups SCG1 to SCGM are expansion units as the number of subscribers increases, but the simultaneous talkie sending unit TKYU is fixed in advance so that it can accommodate all the subscriber circuit groups that can be installed on one rack. Since the system is located in a central area, there is a problem in that it becomes uneconomical when the number of subscribers is small.

TKYDV1 to TKYDVM are installed in a distributed manner, and a control circuit CONT is provided commonly to all subscriber circuit groups SCG1 to SCGM. The talkie sending circuits TKY1 to TKYM are connected to corresponding talkie drive circuits TKYDV1 to TKYDVM, respectively. In addition, the control circuit CONT is a subscriber circuit control drive circuit SCDV11 to SCDV11 in the subscriber circuit.
SCDVMN and the above talkie drive circuit TKYDV1~
Connected to TKYDVM. Other configurations in this embodiment are shown in FIGS. 1 and 2 described above.
It is similar to that shown in the figure. Next, the operation of the talkie transmission system of the present invention will be explained with reference to FIG. During normal operation of the exchange, the control circuit CONT receives subscriber circuit control commands (SD signals) sent from the central control unit (not shown) and connects the electronic contacts (SD points) of each subscriber circuit SC11 to SCMM. ), and by changing their combination, controls the supply of communication current, sending and stopping of the calling signal, return test, drawing of the test line, etc. On the other hand, when it is determined that the exchange system is down, a simultaneous talkie activation signal is sent to the control circuit CONT by a maintenance person's key operation. control circuit
CONT is a control signal that autonomously generates a signal pattern for talkie transmission and turns on only the subscriber line drop-in switches LT11 to LTMN in each subscriber circuit SC11 to SCMN, and a talkie transmission circuit TKY.
The control signal for operating the relay TKR (Fig. 2) of 1 to TKYM is connected to the subscriber circuit control drive circuit.
SCDV11 to SCDVMN and talkie drive circuit
Send to TKYDV1 to TKYDVM. Furthermore, compared to the conventional subscriber circuit control circuit SCCONT, the control circuit CONT requires only the addition of one control signal bit to the conventional control signal for controlling the on/off of the talkie drive circuit, and requires less hardware. There is almost no difference in quantity. All relays in the subscriber line drop-in switches LT11 to LTMN and the talkie sending circuits TKY1 to TKYM that receive control signals from the control circuit CONT operate, and the talkie sound source → transformer T → talkie sending circuits TKY1 to TKYM → subscriber line drop-in line l 11
~l no →Subscriber line drop-in switch LT11~
In the LTMN route, the talkie tone is heard on the subscriber phone.
It is sent to SUB11 to SUBMN, and can be heard by a subscriber in an off-hook state as a talkie tone. While the talkie transmission circuits TKY1 to TKYM are in operation, each subscriber circuit SC11 to SCMN is in an off state.
Since only the subscriber line drop-in switch is in the on state, the talkie sending circuits TKY1 to TKYM in each subscriber circuit SCG1 to SCGM only need to consider the heating conditions of their own circuits, and the talkie sending circuits of other subscriber circuit groups There is no need to consider TKY1 to TKYM. Therefore, miniaturization has been achieved, and it has become possible to accommodate each subscriber circuit group.
