Abstract: A programmable network convergence edge-switch (NCES) deployed in the corporate enterprise that enables services delivered by the telecommunication carriers to interoperate and integrated with databases and applications within corporate enterprises. The NCES enables integration of services deployed over Advanced Intelligent Networks (AIN), softswitches (SS) and Session Initiation Protocol (SIP) switches over one set of interfaces on one end and data deployed over IP network over the other set of interfaces on the other end. Integrating carrier services with enterprise data generates an opportunity to build the next generation of advanced applications and services that transcend beyond a single-network single-protocol to a multi-network multi-protocol environment.
