ABSTRACT:
Large-scale time-division switching arrangements often consist of a central switching network and a series of so-called concentrators. For establishing an H1 switching a series of wideband concentrators are connected to a central wideband switching network if the wideband concentrators are of a modular structure and communicate through an internal bus system and an interface circuit with the central wideband switching network connected thereto, a distribution switching in the direction of the subscriber station and a testing of the concentrators while in operation can be effected in a simple way.
