Abstract

A system and method for transmitting, receiving, generating, and processing call signaling comprises a signaling point to receive and transmit call signaling over access links to, for example, time division multiplex (TDM) communication devices. A signaling interface receives and processes message parameters and call signaling and transmits call signaling and message parameters between the signaling point and a call processor. A call processor processes call signaling and can transmit call signaling message parameters to an asynchronous transfer mode (ATM) matrix for transmission through an ATM network or to the signaling interface for transmission of call signaling messages from the signaling point. An ATM matrix transmits call signaling message parameters on designated virtual paths/virtual connections (VP/VCs) to communication devices.

Dependent claims

A system for connecting a call having call signaling and user communications, the system comprising:

a signaling interface adapted to receive and process the call signaling to determine call information elements, to transmit the call information elements, to receive new call information elements, and to transmit the now call information elements as new call signaling;
a call processor adapted to receive the call information elements from the signaling interface, to process the call information elements to determine the new call information elements, to determine a destination for the new call signaling, to select either a Signaling System #7 (SS7) format or a packet signaling format for the new call signaling, and to transfer the new call information elements to the signaling interface in either the SS7 format or the packet signaling format;
and
an asynchronous transfer mode matrix adapted to receive the new call signaling in the packet signaling format from the signaling interface and to transmit the new call signaling using an asynchronous transfer mode connection.
