PURPOSE:To take an optional multiplexing degree independently from a channel, by setting a multiplexing unit to integer times of a voice channel so that one or more channels in the time division channel can be used in common, and setting a path to be connected to a signal equipment optionally. CONSTITUTION:A channel for a circuit control signal which has come in a channel device is assigned as half-fixed, as it is by a CPUCC, as a path to a channel to which a digital signal equipment is connected, in the same way as an inter-office trunk line, in the channel system. In this case, a route of a broken line in a time division switch TDSW shows a path of said signal channel which has been assigned as half-fixed, and an interface of the time division switch TDSW and a digital multiplexing signal processing equipment D-SIG is multiplexed by each signal channel. In this way, one or more channels in the time division channel are used in common, and a path to be connected to the signal equipment is set optionally. |
