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 Signalling System 7 (SS7) 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 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 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 provider's 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: signalling or call control. The PGW 2200 configured for signalling provides an SS7 signalling interface for the Cisco AS5x00 Series voice gateways and access servers. In this configuration, the PGW 2200 provides the SS7 signalling 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 SS7 links from the PSTN, performs numerous analysis and routing decisions, and communicates with the media gateways through MGCP while providing signalling to the H.323 or SIP network. In this configuration, the PGW 2200 performs the primary functions of the call control (Figure 1).

Figure 1

Cisco PSTN Gateway Application


Signalling Enabled Applications

The Cisco PGW 2200 is a key component of the Cisco Voice Infrastructure and Applications (VIA) Solution and the Cisco Wholesale Dial solution. In the Cisco VIA solution, it enables SS7 interconnect for voice gateways—an H.323- and SIP-based VoIP capability and in addition, can act as a softswitch for international and national transit services.  In the Wholesale Dial solution, the PGW 2200 enables SS7 interconnect for access servers.

SS7 Interconnect for Voice Gateways

In many cases, service providers, whether installing new or operating existing H.323 and SIP networks, are restricted to using expensive and sometimes unavailable PRIs. The Cisco SS7 Interconnect for Voice Gateways solution allows these customers to interconnect to PSTN networks, avoiding costly PRIs. Service providers can use this solution to eliminate unnecessary paths through TDM switches. Figure 2 shows the role of the Cisco PGW 2200 configured for signalling in this solution.

SS7 Interconnect for Access Servers

Carriers are interested in new revenue generation and capital investment reduction. Driven by the new business model of wholesale services for the retail Internet service provider (ISP), service providers require SS7/C7 interconnect as part of a complete wholesale dial solution to reduce overall operational costs and scale to million-port networks.

Figure 2

Call Control-Enabled Applications

The Cisco PGW 2200 enables packet telephony applications, including:

  • Multiservice (voice and data) businesses and residential access using SIP and H.323
  • Cisco VIA international and national transport
  • Dial Offload Service

This application provides a network architecture foundation that enables service providers to bridge the boundary between the legacy PSTN and today's packet telephony networks. The Cisco PGW 2200 interfaces with other components in an H.323 or SIP packet network, including end terminals, access gateways, and Cisco SIP Proxy Servers or H.323 gatekeepers. Bearer traffic flows between media gateways in the SS7 transit zone, and media gateways or end devices in the VoIP access and services zone. IP signaling traffic flows between the Cisco PGW 2200 and Cisco SIP Proxy Servers or H.323 gatekeepers.

Figure 3

Cisco PGW 2200 Call Control Architecture and Applications


The transit-switching application, shown in Figure 3, is targeted at carriers who are looking for an alternative to traditional tandem switching or an offload of their existing TDM network infrastructures. In this application, the Cisco PGW 2200 provides SS7 interconnect to the PSTN and provides advanced call-routing and screening functions across a packet network using high-end Cisco media gateways. The current release supports Cisco MGX 8000 Series Carrier Voice Gateways and the Cisco AS5000 family of voice gateways.

Cisco PGW 2200 Architecture and System Components

Continuous Service Architecture

Figure 4 shows the continuous service node architecture, which consists of redundant Sun hosts, the Cisco PGW 2200 software, and Cisco signalling link terminals (SLT). The redundant hosts and SLTs communicate through a dedicated signalling control IP network.

Figure 4

Cisco PGW 2200 Architecture


Maintaining the SS7/C7 signalling links is critical to being part of the SS7/C7 network. SS7/C7 "A" or "F" links from the PSTN terminate on the SLTs. The SLTs handle processor-intensive Message Transfer Part Layers 1 (MTP1) and Layer 2 (MTP2) of the SS7/C7 stack, then encapsulates MTP Level 3 (MTP3) and above layers in Reliable User Datagram Protocol (RUDP) and forwards to both the active and standby hosts. The higher level layers are passed to the Cisco PGW 2200 host over an Ethernet interface, including:
  • MTP3
  • Integrated Services Digital Network (ISDN) User Part (ISUP)
  • Signalling Connection Control Part (SCCP)
  • Transactional Capabilities Application Part (TCAP)
  • Advanced intelligent network (AIN)
  • Intelligent Network Application Protocol (INAP)

The Session Manager Protocol maintains the IP link between the SLT and the hosts, maintaining the integrity of the signalling links. The single-purpose, Cisco IOS® software-based SLT software operates on the widely deployed NEBS-compliant Cisco 2600 Series Multiservice Access Router Platform. The dual-port drop-and-insert capability of the Cisco SLT grooms bearers and F-link signalling traffic when fully associated mode signalling is used. This avoids the expense of additional M1/0 multiplexing when using F links, further lowering costs. Four links are terminated per SLT. Link sets are terminated across multiple SLTs to eliminate single points of failure. Each Cisco PGW 2200 node is represented by a point code, regardless of the number of SLTs. If required, a node can appear as multiple point codes as well. For further information, please refer to:


A high-speed Cisco LAN switch connects components within a Cisco PGW 2200 node. This LAN switch is dedicated for signalling traffic between and within Cisco PGW 2200 node components and between a Cisco PGW 2200 node and media gateways. A LAN switch can be shared by Cisco PGW 2200 nodes, providing connectivity between nodes and the media gateways. For carrier-class operations, the Cisco Catalyst® 5000 or 6000 Series Switch is typically used. For example, the Cisco Catalyst 5000 series supports multiprotocol and multilayer switching and connects through a wide selection of interfaces. Redundant LAN switches are used in a Cisco PGW 2200 node for continuous fault-tolerant operation. For Cisco Catalyst 5000 Series product information, refer to:


The Cisco Catalyst 5000 or 6000 Series Switch is not a mandatory component of the Cisco PGW 2200; other LAN switches may be used.

Software fault tolerance and redundant operation are achieved by check pointing call-context information between the active and standby host. This process, along with main memory database synchronization, enables switchover from active to standby host with no disruption of active calls.

Selected Cisco PGW 2200 Features and Capabilities

Signalling Configuration

The Cisco PGW 2200's MGC software may be configured for signalling to provide SS7 interconnect for voice gateways and access servers. The PGW 2200 maintains an internal mapping of bearer circuits on the PSTN side to those on the gateways to enable SS7/C7 interconnection, while providing necessary carrier functions such as alarms, statistics, and CDRs for billing.

The signalling configuration uses extended Q.931 over IP to provide signalling to the gateway, continuity test (COT), and maintenance functions. For added resiliency, the Redundant Link Manager (RLM) is unique to the Cisco solution. The RLM allows for multiple, redundant IP paths to be treated as one path by upper layers. The design is optimized for message-based transmissions over redundant links. The instant recovery of RLM ensures connectivity from Cisco PGW 2200s to gateways.

Call Control Configuration

In the call control configuration, the PGW 2200 terminates the SS7 links from the PSTN, performs number analysis and routing decision, communicates with the gateways through MGCP while providing signalling to the H.323 or SIP network. Cisco has worked to define MGCP through the Internet Engineering Task Force (IETF) and International Telecommunications Union (ITU). Universal protocol-support capabilities in the Cisco PGW 2200 allow it to quickly adapt to any future call-control standards.
