The IP Network Interface Series 3 Card is an IP plug-in line card for the Converged Services Platforms (CSP). It enables the CSP Platforms to support IP, performing two-way gateway conversion between circuit-switched and packet-switched media. Developers can use the IPN Series 3 Card to build revenue-generating voice, fax, and modem-over-IP services in which a CSP Platform acts as a gateway or media server in a converged services network. The IPN Series 3 Card transcodes data from PCM to packet technology, compresses it, and provides silence suppression, echo cancellation, and jitter buffering to improve quality. The IP Network Interface Series 3 Card, along with SIP and H.323 signaling, provides a true gateway environment, enabling developers to deliver an application server, signaling engine, gateway, and media server, all in a single system. This unified architecture can translate into significant cost savings, reduced development time, and simplified operation for developers and service providers.
