CISCO PGW 2200
|
| 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).

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.

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.

| 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.

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:
http://www.cisco.com/en/US/products/hw/vcallcon/ps2152/products_data_sheet09186a0080091b58.html
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:
http://www.cisco.com/en/US/products/hw/switches/ps679/index.html
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
checkpointing 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.

World-Class Element
and Network Management The Cisco PGW 2200 has a comprehensive
and user-friendly management environment. Detailed measurements and
statistics are used to monitor the system. It has a full suite of
operational and signalling alarms. This is a true telecom network
device, with data for accounting, traffic engineering, performance
monitoring, network planning, and systems management. Carrier-grade
call-detail records (CDRs) provide the appropriate data for downstream
billing and network planning systems. A comprehensive set of
troubleshooting tools, including unique signalling interworking
instruments, command-line interfaces (CLIs), TL-1-compliant formats,
Simple Network Management Protocol (SNMP) Management Information Bases
(MIBs), graphical user interface (GUI) tools and viewers, and a
subnetwork management system, allows the user to manage a
carrier-class PSTN gateway. For further information, please refer to:
http://www.cisco.com/en/US/products/hw/vcallcon/ps2027/index.html
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.
