Abstract
PURPOSE:To improve the working efficiency of a service channel, by writing and leaving an originating register in a receiving path memory at the point of time when it has become possible to send and receive a signal between an extension and a trunk. CONSTITUTION:In a highway speech memory HWSM, service PCM data from an extension EXTo and a trunk COj related to connection are stored in memory addresses corresponding to the respective time slots, by a fixed sequential pulse. The PCM data stored in the HWSM are sent out to a transmission highway path THWn in accordance with the information stored in a transmission path memory TPM, and are transferred to the COj. In this way, a signal can be sent and received between the EXTo and the COj. At this point of time, an originating register REGK is written and left in a memory address corresponding to a service channel which has been assigned to an originating extension of a receiving path memory RPM. In this way, a dial signal from the EXTo, which is sent out to the COj is monitored.
