14-2 Compact T1 - Release 6.1
Router (CMG) Card
Overview
Overview
The Customer Media Gateway (CMG) Service card for the Compact T1 platform
combines IP Router functionality with the ability to translate circuit-based voice
services into packet-based voice services, or Voice over IP (VoIP). The CMG Service
card provides a cost-effective migration path for both existing Compact T1 TDM-based
deployments and greenfield VoIP applications.
When installed in an Compact T1, the CMG Service Card enables the packetization of
voice services using the Media Gateway Control Protocol (MGCP). This allows
standards-based voice processing, call control and signaling communications with the
service provider’s call agent or softswitch. The card also provides IP routing and
bridging between LAN and WAN connections for VoIP and data traffic, plus IP QoS/
policy management features – facilitating a truly integrated, packet-based voice and
data delivery solution.
Under control of the call agent, the CMG Service Card equips the service provider to
offer revenue generating CLASS and IP Centrex calling features, enabling service
migration from traditional Class 5 architectures to softswitch solutions. Distinctive
ringing, call waiting, DTMF tone detection, call progress tone generation, and caller ID
are just some of the many signaling and service solutions that are offered through the
CMG Service card.
With the availability of the CMG Service Card, the Compact T1 becomes the first
broadband service distribution gateway that supports modular voice services over IP,
providing voice/data policy management as an integrated, coordinated, platform-wide
capability. The integrated routing protocols ease network deployments, while the IP
class-of-service traffic management features simplify the aggregation of sensitive
voice packet streams into a multi-service converged data network.
As a component of the Compact T1 platform, the CMG Service card provides several
local and remote management options. The card can be locally configured and
managed using the menu-based interface, a Command Line Interface (CLI) via the on-
card user dataport or through the Compact T1 Controller. Remote management is
accomplished directly from the Compact T1 Controller over an in-band DS0
management channel, a separate SNMP network management facility, or in-band via
any configured IP WAN interface.
