4
units with a single device that supports business-class voice, Internet-
access, and data services.
The IP Router Card also supports Point-to-Point Protocol (PPP), Frame
Relay, PPP in Frame Relay, and GRE tunneling, as well as packet filtering,
Spanning Tree Protocol (STP), and Dynamic Host Configuration Protocol
(DHCP).
With three levels of security, the IP Router Card keeps
communications safe. It supports PAP and CHAP, Network Address
Translation (NAT), NAT Bypass, Port Address Translation (PAT), and
RADIUS login authentication.
Media Gateway VoIP Router Card
This card combines IP router functionality with the ability to translate
circuit-based voice services into packet-based Voice over IP (VoIP).
Installed in the Compact T1 Channel Bank, the Media Gateway VoIP
Router Card enables you to packetize voice services using the Media
Gateway Control Protocol (MGCP). This way, you can establish a
standards-based voice processing, call control, and signaling
communications. As a service provider, for instance, you can offer
CLASS (Custom Local Area Signaling Services) and IP Centrex services
in which customers can share data and voice via the same line.
The card also provides IP routing and bridging between LAN and
WAN connections for VoIP and data traffic, plus IP QoS (Quality of
Service)/policy management features. A built-in 10BASE-T/100BASE-TX
Ethernet port enables you to connect to voice or local LAN traffic.
Integrated routing protocols ease the job of deploying the card in a
network. The card also supports multiple types of softswitches, so
connecting telephony services through the media gateway to VoIP
services isn‘t a problem either.
What’s more, the Media Gateway VoIP Router Card features voice
compression, silence suppression, comfort noise generation, and echo
cancellation. Distinctive ringing, Call Waiting, DTMF tone detection, call
progress tone generation, and Caller ID are just a few of the many
signaling and service solutions are also supported by the card. You can
even tailor tone databases to support call-progress tones and cadences
for a specific country. Selectable FXS impedances provide worldwide
coverage of line impedance variations.
A maximum of six Media Gateway VoIP Router Cards can be installed
in the Compact T1 Channel Bank.
