Abstract

In the invented device, input end of normal close type relay switch, input end of MOS electronic switch module A and input end of voltage comparator module is connected to local power source respectively. Output end of voltage comparator module is connected to input ends of optical coupler A and B respectively. Output end of optical coupler A and B is connected to another input end of MOS electronic switch module A and input end of MOS electronic switch module B respectively. Another input end of optical coupler A and B are connected to output end of system power source conversion module respectively. Output end of the said relay switch, output ends of MOS module A and B are connected to input end of the said conversion module respectively. Another input end of MOS module B is connected to remote supplied power source. Under soft exchange architecture, when normal service operation is interrupted caused by abnormity of local power source, service same as PSTN network can be supplied.

Description

technical field [0001] The invention belongs to the category of communication technologies, and in particular relates to a method for realizing remote power supply by multi-port integrated access equipment. Background technique [0002] At present, under the known softswitch architecture, using integrated access equipment (integrated access) to provide local telephone services and complete voice service transmission on broadband networks has become a preferred solution for replacing current narrowband PSTN switches and constructing next-generation network switches. Since the multi-port integrated access equipment is placed in the corridor, there is a problem of how to ensure power supply in case of emergency. This problem is one of the problems that plague the large-scale commercial use of integrated access devices under the softswitch architecture. Currently, there is no solution in similar products at home and abroad. Solving this problem als...
