Abstract

A protection switching system (10) includes a plurality of telecommunications modules (12, 14A. 14B, 16A, 16B) for processing and/or switching telecommunications signals. A first module (12) provides signals to one pair of modules (12A, 12B), which are in turn connected to another pair of modules (16A, 16B). A standby module (14B, 16B) controls the switching of all the modules (12, 14A, 14B, 16A, 16B) in the system (10) which require switching in the event that a standby module (14B, 16B) is activated. A controller monitor circuit (20) monitors the faults present on the working modules (14A, 16A) and, if a fault is detected, signals the corresponding standby module (14B, 16B), which in turn provides protection switching.
