ICS2000T Media Gateway
[ specifications  ]
 Unified
Network Architecture™
Convergent Networks’ Unified Network Architecture consists of the PacketMatrix™ Controller
(PMC), the ICS2000 media gateway, the ICSG™ signaling gateway and the Aladdin™ management
system.
The ICS2000 media gateway provides flexible voice call interworking between IP, ATM
and TDM circuits for both trunking and access applications. Screening, blocking, number
translations and routing
functions are provided to other network elements via the PMC. The PMC holds routing and
service intelligence for a network of ICS2000 media gateways, acting as a mediation point
between IP applications
and AIN applications, and a peering point to other next generation call management and
application elements in the network. The ICSG provides consolidated SS7 signaling support
for a network of ICS2000
media gateways and PMCs, while Aladdin provides
standards-based element management and billing mediation.
Single Switching Architecture, Multiple Applications
The ICS2000 media gateway is a proven, scalable and flexible solution for delivering
next-generation and traditional voice and data services. Using standard, open interfaces,
the ICS2000 can be deployed
in conjunction with other Unified Network Architecture elements or with third party
products to support the following applications:
- Packet Tandem - The ICS2000 is a robust platform for Class 4 packet tandem applications offering
tandem switch feature equivalence, while enabling new services through SIP. In addition,
the solution supports ATM and IP-based long distance services for carriers who want to
communicate voice calls over long distance trunks
between their media gateways. When deployed with the PacketMatrix Controller and ICSG
Signaling Gateway,
the solution
provides a complete set of interfaces, including Direct access line, T1 CAS, IMT, PRI,
ATM, and IP supported by rich SS7, LNP, call routing, screening, and service capabilities
of a Class 4 switch.
- PRI Offload and Business Voice Services - The ICS2000 offers a high-density, low-cost alternative
to offload dial-up modem traffic from today’s voice-centric Class 4/5 switches, while
also serving as an economical solution for delivering business voice services, such as
PBX trunking over T1 CAS, PRI, and ATM.
- Class
5 Services - The ICS2000 acts as both a packet trunking gateway, switching packet-based
voice calls originating from customer-located IP or ATM-based equipment to the PSTN,
and as an access gateway, supporting
GR-303 to deliver features to traditional DLC based access networks. The ICS2000 media gateway
delivers traditional CLASS features, such as call forwarding, call waiting, caller
ID and voice mail, in addition
to regulatory requirements such as E911 and CALEA. An open, SIP-based architecture supports enhanced
voice applications through third party application servers, such as carrier hosted IP PBX service,
messaging, conferencing and IP call center.
Scalable Interworking Between PSTN and Broadband Networks
The ICS2000 media gateway works as a PSTN gateway in conjunction with the ICSG signaling
gateway and PacketMatrix Controller to switch and interwork calls between any combination
of TDM and packet networks. The solution integrates a number of signaling and call control protocols
for both TDM and packet networks, and provides full interworking functions which allow,
for example,
UNI 4.0 signaling devices to switch calls across SS7 ISUP-based networks. An internal
SIP user agent directly interworks the ICS2000 with SIP terminals and service applications, while
the PacketMatrix
Controller further extends the ICS2000 ’s application capabilities with tandem features.
The
ICS2000 works in conjunction with the PMC to achieve seamless integration of packet and
PSTN networks. The PMC directs call processing through the most efficient path in a large,
distributed network - routing calls from a packet network to the PSTN and from the PSTN to a packet
network. The PMC acts as a service mediation point between SIP and AIN domains, and has
the ability
to link
applications from IP to the PSTN and extend network resources to third-party application
servers using SIP to enable applications such as IP Centrex, unified messaging and IP call
center.
PSTN endpoints on the ICS2000 media gateway are represented by the PMC to applications
as a set
of fully managed SIP or ATM endpoints. For calls originating from the PSTN and terminating
in the packet network, the PMC performs a route translation to determine which application
element is managing
the terminating endpoint. For calls originating in the packet network and terminating
in the PSTN, the PMC first acts as a redirect server to direct the call to the best gateway
interface, then performs
service selection functions based on the call profile. This simplifies provisioning and
allows the service provider to protect and control the details of the network topology.
High-Performance
Interface Modules for ATM, TDM and IP
Leveraging a native ATM-based switching fabric, the ICS2000 allows carriers to deliver
packet-based services to end-users by employing a 20-slot, NEBS Level 3-certified
chassis with a 10 Gigabit switching architecture (5 Gigabit redundant). Two slots are dedicated
to the redundant
switching fabric and control processor, and the remaining 18 slots are available
for
IP service units (ISU), TDM service units (TSU), ATM service units (ASU) and Time Slot
Processors (TSP). Extreme Density and Performance
A single ICS2000 chassis can switch up to 24,192 protected calls in a fully redundant
configuration, and by stacking three ICS2000s in a standard seven-foot rack, more
than 72,000 IP calls
can be supported. Further, a single ICS2000 can scale to more than 16,000 non-blocking
simultaneous Class 5 users (over 80,000 subscriber lines with 5:1 oversubscription).
Multiple
ICS2000 chassis can be supported by a single ICSG signaling gateway with a single point
code supporting up to 500,000 non-blocking DS0s. For maximum scalability, these ICS2000s
can then be interconnected to form a virtual switch over an IP or ATM-based network. When leveraging
the
distribution of call control between the ICS2000 media gateway and ICSG signaling gateway
in tandem and trunking applications, SS7 signaling capacity is designed to scale up
to 10 million
Busy Hour
Call Attempts (BHCA).
Carrier-Grade Availability and Redundancy
The ability to configure the ICS2000 with economical 1:N
interface redundancy, as well as full common equipment redundancy, provides a highly reliable
platform from which to provision
services.Coupled with hot standby operation across all interfaces with stable call presentation
and 99.9999% availability, the NEBS-certified ICS2000 media gateway and ICSG signaling
gateway provide carriers with the telephony-grade reliability required of today ’s public networks.
The
Virtual Switched Network
Convergent Networks’ Unified Network Architecture allows carriers to create a Virtual Switched
Network (VSN), providing the advantages of distributed processing, with the benefits of
central administration. The VSN, which consists of the all of the equipment in a network that share
the
same call routing data, provides a revolutionary and extremely cost-effective alternative
for building out carrier infrastructures. Although multiple ICS2000s and PMCs can be distributed
in a VSN, service
providers can manage and input all service data centrally in a single PMC Database, easily
provisioning associations with ICS2000 media gateways in the network. |
