Method and system for hitlessly rearranging connections in a cross-connect communications network

摘要

A method and system for hitlessly rearranging a communications matrix and maintaining connections of previously connected signals forms an immediate and temporary connection configuration of a predetermined input gate to a predetermined output gate through a dedicated center stage switch of the communications matrix. The method and system use a predetermined center stage switch other than the dedicated center stage switch to establish a parallel connection configuration from the predetermined input gate to the predetermined output gate. At the input gates, the parallel connection configuration forms a head-end-bridge. At the output gates, the parallel connection configuration forms a receive-end-switch. Once parallel connections exist through the predetermined center stage switch and the dedicated center stage switch, the connections through the dedicated center stage switch are disconnected to free the dedicated center stage switch. The result is that the method and system provide hitless rearrangements of communications matrix connections.
