Class 4 Call Manager (C4CM)

The Clarent® Class 4 Call Manager (C4CM) is the strategically crucial central call control element of IPVision’s end-to-end PSTN access softswitch solution. This Class 4 Call Manager cost-effectively performs the key functions of call routing, user authentication, connection control, internet offload, and signaling of the Clarent® BHG. (Connection control refers to the setup and teardown of calls).
User authentication is specific to the processing of transactions after the Clarent® Command Center clears user authentication and establishes the account to be charged.
The interface between the Clarent® C4CM and gateway includes TPNCP and MGCP. This suite of protocols subsequently accommodates the full spectrum of service providers communications needs. Adopting these open protocols assures that the Clarent® C4CM will be a smooth integration for IPVision’s customers across the globe, with an inherent scalability that takes traditional circuit switching to the next level of telephony evolution.
The Class 4 Call Manager (C4CM) is carrier-grade, UNIX based, NEBS-compliant. As the central call control element in IPVision’s PSTN Access Softswitch solution, the C4CM is designed to augment or replace Class 4 telephony switches.
