ABSTRACT:
The Flexible Enhanced Signaling Subsystem (FESS) performs table-driven processing of incoming and outgoing messages and also handles multiple message types and trunk groups. A message received by the FESS is first processed by an incoming signaling module which performs all necessary transformations to the message to enable the existing switch processing to handle any incoming message. The incoming signaling module, being table-driven, can be easily modified to handle any new message types which may be created. The message is then processed by an intermediate signaling module which includes the existing call processing, The intermediate signaling module may pass through messages, or it may generate new messages. In either case, an outgoing signaling module performs all necessary transformations to messages output from the intermediate signaling module to enable the outgoing trunk, downline switch or downline network to handle the message properly.
