Abstract

PURPOSE:To make it possible to use efficiently switch networks by freely constituting line-concentrated and line-unconcentrated type switch network blocks according to traffic. CONSTITUTION:At the side of line-concentrated type switch network blocks 21 and 22, at least one line-unconcentrated type switch network block 23 is provided, and they are connected to line-unconcentrated type switch network blocks 24 and 25 via junctor 26. For example, subscribers are connected to blocks 21 and 22, a PBX, PBX circuits with much traffic, trunks or the like are to block 23, an outgoing trunks, intra-office trunks, etc., are to blocks 24 and 25. The driver circuit of line-concentrated and line-unconcentrated type blocks is made into the replaceable module constitution, so that the system constitution can be given multiformity.
