ABSTRACT:
A communications network connected to a plurality of communications lines and method of managing connections to the network. The presence of an interface connection to a communications line is detected and initialized for signaling. First, the interface connection is initialized for a first signaling protocol, e.g., CCS. If initialization is successful, the connection uses that first signaling protocol. If not, the interface connection is initialized using a second signaling protocol, e.g., CAS. If initialization to the second protocol is successful, the connection uses that second signaling protocol. Otherwise an error message is returned.
