Abstract:

To efficiently acquire a time slot(TS) for an H channel on a channel where telephone and FAX channels are intermingled by setting a subscriber class to an H channel terminal and acquiring the TS corresponding to the subscriber class.

In the multi-directional multiplex communication system provided with a slave station 3 that accommodates terminals 61-63 compatible with channels where an analog channel 54, a basic interface channel 55 and a primary group speed interface 56 are intermingled and with a base station 2 that makes wireless connection with the slave station 3, a subscriber data management section 24 decides in advance a subscriber class with respect to a TS use right of the H channel terminal 63. Upon the receipt of a call connection request from the H channel terminal 63, the base station 2 references a TS management section 23 to monitor an idle TS and when call connection is disabled due to deficiency in the idle TS, a TS acquisition control section 26 controls connection on the basis of the subscriber class to reserve the TS between the base station and the slave station for the H channel terminal.
