ABSTRACT:
A telecommunications system includes an access terminal coupled to subscriber lines, a local exchange carrier (LEC) network, and a channel unit card coupling the access terminal to the LEC network. The channel unit card includes a processor configured to convert call processing signals received from the LEC network and formatted according to a protocol used by the LEC network to a message-oriented signal whose format is independent of the protocol used by the LEC network. The message-oriented signal then can be delivered to the access terminal. The channel unit card processor is further configured to convert message-oriented signals representing call processing communications received from the access terminal and having a format independent of a protocol recognized by the LEC network to one or more signals formatted according to the protocol recognized by the LEC network. The signals converted to the format recognized by the LEC network then can be routed to the LEC network.
