PURPOSE:To realize a system where meter pulses can be transmitted in the same repeating system as general telephone sets, by transmitting pulses while interrupting the channel at a meter pulse transmission time. CONSTITUTION:When it becomes time to transmit meter pulses while the subscriber (SUB) having a private call meter (MTR) is in the course of outgoing connection service, an interrupt path is searched for the channel of the subscriber (SUB) and the outgoing tunk (OGT). The interrupt path is connected to the meter pulse transmission unit (MME) on the switch frame (SWF) by the switch driving unit (SC), and the relay of the meter pulse transmission unit (MME) is controlled through the signal distributing unit (SD), thereby transmitting meter pulses. After transmission, the interrupt path and the meter pulse transmission unit (MME) are released to hold the same connection as general call till the next pulse transmission time. |
