In TKYM, a current constantly flows 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, large resistors, etc. Measures are taken to prevent fever. Incidentally, the role of the Zener diode D is to supply a potential necessary for loop formation during off-hook when the telephone is a Plj telephone. -Sai talkie sending unit TKYU
In this example, M talkie transmitting circuits that require heat generation countermeasures are mounted in a concentrated manner. Further, the subscriber circuit groups 5CGI to 5SCGM are expansion units as the number of subscribers increases, but the simultaneous talkie transmission unit (TKYU) is installed permanently.

追加で良く、ハード量はほとんど差がない。While the talkie sending circuit is in operation, subscriber circuits 5CII to SC
Since the MN is in the off state (only the subscriber line lead-in switch is on), the talkie sending circuits TKY1 to TKYM in each subscriber circuit group 5CGI to SCGM only need to consider the heat generation conditions of their own circuits; There is no need to consider the talkie sending circuits TKY1 to TKYM of the user circuit group. As a result, it has been made smaller and can be accommodated within a subscriber circuit group. Compared to the conventional subscriber circuit control circuit 5CCONT, the control circuit C0NT requires the addition of only one control signal bit, and there is almost no difference in the amount of hardware.

よシ制御されるという効果がある。As explained above, the present invention realizes miniaturization of the device by distributing the talkie sending circuit to the subscriber circuit group and installing the control circuit in common with that of the subscriber circuit.
It is also economical to be included in an expansion unit as the number of subscribers increases, and there is an effect that simultaneous talkie activation is controlled by one control circuit.
