Cisco PGW2200 Softswitch The Cisco PGW 2200 is a flexible multiprotocol Media Gateway Controller (MGC) that provides a bridge between the legacy Public Switched Telephone Network (PSTN) and next-generation packet networks?supporting either simple Signaling System 7 (SS7) or C7 interconnect or providing intelligent call control and routing functions. The Cisco PGW 2200 provides a consistent, unified interconnection that can handle dial-up services, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), and H.323, as well as future standards. The PGW

2200 allows service providers to deploy and operate multiple network solutions while maintaining a stable interconnect to the PSTN.

Carrier-Grade and Central-Office Ready The Cisco PGW 2200 is carrier-grade and central-office ready. The PGW 2200 supports a continuous service architecture with no single point of failure. All critical components are deployed in redundant configurations, and all stable calls are preserved in the event of a switchover. The application software runs on Network Equipment Building Systems (NEBS) Level 3-certified UNIX open-computing platforms. These carrier-grade servers, along with the continuous service software design, enable carrier-class availability.

Cisco PGW 2200 Value Proposition The PGW 2200 is an essential component of a service providers strategy for migrating to emerging packet voice technologies. The Cisco PGW 2200 provides seamless interoperability between existing time-division multiplexing (TDM) switches and new packet networks, allowing providers to transition to more cost-effective and flexible services even while these new technologies continue to evolve. This seamless interoperability is achieved by introducing the power and dependability of SS7/C7 signaling for interconnect with the packet voice networks.

The Cisco PGW 2200 allows providers to interconnect to the PSTN with more cost-effective intermachine trunks (IMT) and SS7 links. The Cisco PGW 2200 brings C7/SS7 signaling that provides significant infrastructure cost savings and time-to-market benefits over those using Primary Rate Interfaces (PRIs) or channel associated signaling (CAS) signaling. This creates an environment that improves a providers competitiveness and reduces operational costs.

The Cisco PGW 2200, deployed with a voice gateway, also allows providers to deploy new revenue-generating services, such as PSTN access for business and residential packet voice applications. A provider also can sell hosted business services to a number of customers, gaining from economies of scale. All of these applications require a platform that bridges the old-world TDM networks with new world IP-based networks.

In addition to operational cost savings and new services, the Cisco PGW

2200 provides a lower first port cost. The distributed nature of Voice over IP (VoIP) solutions allows service providers to deploy a single PGW 2200 and a small number of gateways, and expand as the demand grows. This flexible configuration of the PGW 2200 solutions is a key component of a service providers portfolio. It allows them to capitalize on market fluctuations by providing a cost-effective and rapid deployment vehicle.

Cisco PGW 2200 Applications The Cisco PGW 2200 in conjunction with the Cisco AS5x00 Series and the Cisco MGX® 8000 Series voice gateways forms a PSTN gateway for a variety of applications, including international transport, national transport, business voice, residential voice, PC-to-phone, Internet call waiting, and dial termination services.

The Cisco PGW 2200 can be configured in two separate modes: signaling or call control. The PGW 2200 configured for signaling provides an SS7 signaling interface for the Cisco AS5x00 Series voice gateways and access servers. In this configuration, the PGW 2200 provides the SS7 signaling interface, and the call control for the voice network is located in the media gateways and gatekeepers throughout the network.

When configuring the Cisco PGW 2200 for call control, the PGW 2200 terminates the C7/SS7 links from the PSTN, performs numerous analysis and routing decisions, and communicates with the media gateways through MGCP while providing signaling to the H.323 or SIP network. In this configuration, the PGW 2200 performs the primary functions of the call control
