METHOD AND APPARATUS FOR BYPASSING A PAYLOAD NODE

摘要

A multi-service platform system (100) includes a rear transition module (102) coupled to receive a DSX signal (105) and a payload node (104) coupled to the rear transition module via a backplane (110), where the payload node is coupled to process the DSX signal. A secondary payload node (114) is coupled to secondary rear transition module (112) via the backplane. A protection bus (150) couples the rear transition module to the secondary rear transition module outside the backplane, where failure of the payload node operates to shunt the DSX signal through the rear transition module to the secondary rear transition module. Failure of the payload node operates to switch processing of the DSX signal from the payload node to the secondary payload node, and the secondary rear transition module independently controls shunting of the DSX signal through the rear transition module to the secondary rear transition module.
