Abstract
A transaction control layer for a signaling gateway that encapsulates multiple signaling systems into a single signaling interface for use by an advanced service node deployed in a telecommunications network. The transaction control layer performs call and resource state management functions for the advanced service node. The single state machine process has the capability of tracking different types of states for both calls and network resources (i.e., circuits) while using industry standards for call processing.
