Converged Services Platform

Overview

Today’s telecommunications market is looking for proven technical solutions that can generate incremental service revenue, quickly and profitably. The CSP features an open and multi-functional design that enables developers to quickly create and deliver new revenue-generating services for both legacy and next-generation networks.

The CSP provides a high-performance applications platform that delivers carrier-grade reliability. The CSP also provides best-in-class call control and signaling support in public switched telephone networks (PSTN), packet network, or converged network environments.

The implementation of the following Internet Protocols (IP) with enhanced hardware and software delivers unparalleled features and functionality.

• Session-Initiation Protocol (SIP)

• H.323

• Real-Time Transport Protocol (RTP)

Refer to the Developer’s Guide: Internet Protocol (IP) for complete information.

Products and Services

The flexible and open programmable architecture allows you to create powerful and differentiated products and services including the following:

• IP Service Node

• Media Services

• IP Centrex/PBX

• Class 4/Toll Bypass

• Protocol Converter/Transcoder

• Single Number Services

• Voice Messaging

• Prepaid Services

IP Service Node

Uses SIP or H.323 protocols to communicate with a softswitch to provide services such as unified messaging, voice recognition, presence, Web, and e-mail applications.

Media Services

Provides Digital Signal Processor (DSP) resources for tones, prompts, announcements, conferencing, and interfaces with external resources such as interactive voice response (IVR) or speech recognition.

IP Centrex/PBX

Uses circuit and packet interfaces to connect enhanced services applications with enterprises and the PSTN.

Class 4/Toll Bypass

Lowers operating costs by eliminating new trunks and point codes with SS7-over IP.

Protocol Converter/Transcoder

Leverages a wide variety of PSTN/IP signaling and IP vocoder standards such as G.711, G723, and G729.

Single Number Services

Enables a caller to dial just one number and lets the system use a predetermined set of parameters to reach the subscriber. The CSP software is used in a number of single number service applications.

Voice Messaging

Allows you to leave a message when you cannot reach someone. The CSP incorporates new and existing enhanced voice messaging services into a single application platform. These services include interactive voice response, voice achieved dialing, single number, fax-on-demand, and paging.

Prepaid Services

Allows customers to pay in advance for long distance and cellular services. Providers can use the CSP to track the time and money used by the subscriber.

Public Switched Telephone Network
Internet Protocol. Part of the TCP/IP family of protocols used to route messages and tracks the addresses of nodes.
Session-Initiation Protocol. A signaling protocol used for establishing sessions in an IP network. A session could be a simple, two-way telephone call, or it could be a collaborative multi-media conference session.
ITU-T standard defines a set of call control, channel setup, and codec specifications for transmitting real-time voice and video over networks that do not offer guaranteed service or quality of service.
Real-Time Transport Protocol. Supports transport of real-time data like interactive voice and video over packet-switched networks.
