Revised: February 7, 2008, OL-11755-03

This document provides an overview of the components, functions and signaling protocols supported by the Cisco BTS 10200 Softswitch.

Objective

The owner/operator of a Cisco BTS 10200 Softswitch can use this document to better understand how the system interfaces with the network, and how it provides network and subscriber features in conjunction with other network elements.

---

Caution Some features involve the use of other network elements (NEs) deployed in the service provider network, for example, gateways, media servers, announcement servers, eMTAs, and SIP phones. See the "Component Interoperability" section of the Release Notes for a complete list of the specific peripheral platforms, functions, and software loads that have been used in system testing for interoperability with the Cisco BTS 10200 Softswitch Release 5.0 software. Earlier or later releases of platform software might be interoperable with the Cisco BTS 10200 Softswitch and it might be possible to use other functions on these platforms. The list in the Release Notes certifies only that the required interoperation of these platforms, the functions listed, and the protocols listed have been successfully tested with the Cisco BTS 10200 Softswitch.
