Converged Services Platforms (CSP) are high-performance, carrier-grade, and open programmable media platforms with integrated signaling capabilities for delivering enhanced telecommunications services. The CSP Platforms bridge existing wired and wireless networks with next-generation IP networks and integrate signaling protocols for IP (SIP and H.323), TDM (SS7, PRI, and R1/R2), mobility, and IN. Their versatility allows the CSP Platforms to speed up time-to-market, reduce costs, increase revenue, and protect a carrier's investment in legacy equipment. The CSP Platforms deliver high levels of media processing and call control in circuit-switched, packet-switched, or converged networks. The CSP 2090 Converged Services Platform is a multi-board chassis with twenty slots that can support up to 2,048 physical voice channels over TDM or IP interfaces or combinations of TDM and IP ports. It can scale up to 14,000 channels with seven nodes that provide the capabilities of a large logical switch. The CSP 2040 Converged Services Platform is a multi-board chassis with seven slots. It uses the same boards as the CSP 2090 and the same system software. It supports up to 1,024 physical voice channels for TDM, IP, or TDM/IP combined solutions. Using the CSP Platforms, developers can create applications with both IP and TDM call control protocols, media processing, and IN signaling that enable feature-rich, network-based converged service implementations. Because of the high degree of flexibility built into their design, the CSP Platforms deliver an open, programmable architecture that can meet the demands of a wide variety of carrier-class communications services from unified messaging to web-based services over many different types of networks.
