Abstract
A signaling system embodying the invention includes, at each SSP, a signaling unit containing a message configuration template containing an entry for each type of message. Each entry contains the complete format for the corresponding message type. For incoming messages, the signaling unit also includes, for each voice channel (CIC) multiple finite state machines which manage operations associated with each of the message types that are involved in CIC control. When a message is received, the message type field in the message is used to identify the message type and invoke the operation of the associated state machine. The state machine then parses the message and performs the operations required by the message.
