Abstract

PURPOSE: To reduce the quantity of cables to be laid by assigning time slots on a tree-shaped time division multiplex transmission line in accordance with the request from a subscriber's apparatus or a local exchange.
CONSTITUTION: The transmission line to which subscriber's apparatus 4 following a local exchange 2 are connected is constituted into a tree-shaped time division multiplex transmission line 5, and this tree-shaped time division multiplex transmission line 6 is used by the TDMA system. That is, the number of time slots set on the tree-shaped time division multiplex transmission line 5 is made smaller than the number of subscriber's apparatus 4 connected to the transmission line, and these time slots are properly assigned to subscriber's apparatus in accordance with requests from subscriber's apparatus 4 or the local exchange 2. Thus, the quantity of cables to be laid is considerably reduced and various service requests are flexibly coped with.
