Abstract:
1. A multi-service platform system, comprising: a rear transition module coupled to receive a DSX signal, wherein the rear transition module further comprises a bypass timer coupled to define a bypass timing period; a payload node coupled to the rear transition module via a backplane, wherein the payload node is coupled to process the DSX signal; a secondary rear transition module; a secondary payload node coupled to the secondary rear transition module via the backplane; and a protection bus coupling the rear transition module to the secondary rear transition module outside the backplane, wherein failure of the payload node operates to shunt the DSX signal through the rear transition module to the secondary rear transition module, wherein failure of the payload node operates to switch processing of the DSX signal from the payload node to the secondary payload node, and wherein the secondary rear transition module independently controls shunting of the DSX signal through the rear transition module to the secondary rear transition module, wherein upon failure of the payload node, the secondary rear transition module periodically communicates a bypass signal to the rear transition module initiating the bypass timing period, and wherein if the rear transition module fails to receive the bypass signal prior to expiration of the bypass timing period, the DSX signal reverts back to passing through the rear transition module to the payload node.
