IPC INTERFACE OF SWITCHING SYSTEM

摘要

PURPOSE: An IPC(Inter Processor Communication) interface of the switching system is provided to inspect a standby IPC path while executing switching interface for an active IPC path in normal state and to achieve the IPC communication of a standby processor, according to the necessity. CONSTITUTION: Between a main switching module(10) and a central data link module(60a) and between a sub switching module(40) and a sub data link module(60b), U-link cables are provided to connect in a cross-duplicated structure. The central data link module(60a) and the sub data link module(60b) are connected through the optical cable for the data transmission of high speed. A central data link module A and a sub data link module A are embodied as an active link(100a). A central data link module B and a sub data link module B are embodied as a standby link(100B).
