Abstract:
A backplane architecture for interfacing diverse types of communication links of a telecommunication network with subscriber circuits served by said network, said backplane architecture comprising:a network interface multiplexer that is configured to provide time division multiplexed signal connectivity and point-to-point multiplexed signal connectivity between said network and line circuit access modules to which said subscriber circuits may be selectively ported; a plurality of non-multiplexed interface connectors, each of which is configured for external connection to non-multiplexed communication links of said network and non-multiplexed communication links of said subscriber circuits, and having a plurality of point-to-point communication ports; and a plurality of access module card slots, each of which is configured to receive a line circuit access module that is programmable to provide a selected one of a plurality of diverse modes of telecommunication connectivity between the network and a subscriber circuit served by the network, a respective line circuit access module having an input/output multiplexer arrangement that is operative to selectively provide connectivity between said line circuit access module and signal paths of said network interface multiplexer, and signal paths of said plurality of point-to-point communication ports.
