Line module protection method and device utilizing said method

Abstract

The present invention relates to a line module protection method and a device utilizing that method. According to the line module protection method of the present invention, line module protection is performed by switching the connection from a broken line accommodating module to an auxiliary module. A plurality of line accommodating modules are included in a line accommodating unit connected to the lines in a network. The plurality of line accommodating modules are divided into a plurality of groups, and the auxiliary module is placed substantially at the same distance from all the groups. Thus, a large number of line accommodating modules for performing line module protection can be employed with one auxiliary module.
