BROADCAST SWITCHING SYSTEM IN MSSR

摘要

PURPOSE: To attain various communication services by providing a line on each outputting side at each self-routing module SRM stage or that an inputting side at each SRM stage with the converting module of switching information. ;CONSTITUTION: In the case of a figure A, the converting module 3 is provided for the input side of SRM 2. When a broadcast cell is outputted from SRM 1, the module 3 converts switching information held by the inputted cell into switching information set at the module 3 and inputs it to SRM 2 at a poststage. The bus of the incoming determination of the broadcast cell is set from a control part 4. The multi-switching cell and an ordinary cell can be identified with VPI/VCI given at the time of setting a call so that they can be identified with data in switching information of SRM after then. Namely, in order to identify the normal/broadcast cells, a bit expressing to be a broadcast cell is provided in switching information of the broadcast cell.;COPYRIGHT: (C)1993,JPO&Japio
