Introduction

Cisco PGW 2200 is a software application based SS7 and C7 signalling controller, that operates in conjunction with Cisco AS 5000 Series Universal Gateways (AS5350, AS5400, AS5850) or Cisco MGX 8000 Series Carrier Voice Gateways. The PGW 2200 carries SS7 and C7 signalling over IP networks allowing seamless VoIP integration with SS7 and C7 TDM infrastructure and visa-versa.

Cisco PGW 2200 can manage SS7/C7 signalling on multiple interconnects on an IP network over a wide area. The SS7/C7 interconnects can be up to 80mls (round trip) from a Cisco PGW 2200 POP, enabling a single PGW POP to manage multiple, distant SS7/C7 interconnects.

Comarra provides unrivalled experience, with an engineering team that has deployed and supported more than 70 PGW 2200 installations in over 20 countries worldwide in all 6 continents and has worked with most of the international SS7/C7 variants.

The Cisco PGW 2200 is carrier-grade and central-office ready. The PGW 2200 supports 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.

The PGW 2200 is an essential component of a service provider's 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 signalling 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 SS7/C7 signalling that provides significant infrastructure cost savings and time-to-market benefits over those using Primary Rate Interfaces (PRIs) or channel associated signalling (CAS) signalling. This creates an environment that improves a provider's 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 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 provider's portfolio. It allows them to capitalize on market fluctuations by providing a cost-effective and rapid deployment vehicle.
