Abstract

PURPOSE: To reduce the quantity of cables to be laid by directly connecting a time division multiplex transmission line to a trunk exchange or a local exchange.
CONSTITUTION: A transmission line 2 to which subscriber's apparatus 1 following a local exchange 5 are connected is constituted as a tree-shaped time division multiplex transmission line, and this tree-shaped time division multiplex transmission line 2 is operated in the individual line signal system of TDMA. A time division controller 3 of the time division multiplex transmission line 2 is provided with a function which converts the format of a signal transmitted by the common line signal system and that transmitted in the individual line signal system to each other, thereby directly connecting the tree-shaped time division multiplex transmission line 2 to the trunk exchange 4 or the local exchange 5. Thus, the quantity of cables to be laid is minimized and a flexible service is provided to general subscribers.
