About Cisco IPVC 3500 Series Gateway Features
Table 1-7 Cisco IPVC 3500 Series Gateway Feature Summary
Feature Description
Interoperability The Cisco IPVC 3500 Series Gateway provides a
high degree of interoperability with other H.323
compliant gateways, gatekeepers, terminals,
proxy, and Multipoint Control Unit (MCU)
products by being based on the H.320 standard
and H.323 protocol stack.
Web-based management The Cisco IPVC 3500 Series Gateway features
the Gateway interface. This is a web interface
used to configure and monitor the
Cisco IPVC 3500 Series Gateway. You can view
and modify all aspects of the gateway
configuration from a remote location using a
Java-enabled web browser.
SNMP management The Cisco IPVC 3500 Series Gateway features
Simple Network Management Protocol (SNMP)
management that supports all aspects of
monitoring, diagnostics, configuration, and
trapping.
Diagnostics The Cisco IPVC 3500 Series Gateway features
front and rear panel LED indicators that display
status for the unit. You can also access remote
diagnostics of the unit through the Gateway
interface, Telnet, SNMP, or a serial port.
Network load balancing The Cisco IPVC 3500 Series Gateway supports
load balancing on the network by communicating
with a gatekeeper through H.323 RAI (Resource
Available Indication)/RAC (Resource Available
Confirmation) messages.
T.120 data collaboration The Cisco IPVC 3500 Series Gateway supports
data transfers in calls between ISDN and IP by
using high speed T.120 in HMLP and VarMLP
formats.
Quality of service (QoS) The Cisco IPVC 3500 Series Gateway features
configurable coding of media packets to achieve
QoS routing priority on the Internet Protocol (IP)
network. The Type of Service (ToS) bits of the IP
datagram header can be configured for priority
level.
Dial plan The Cisco IPVC 3500 Series Gateway supports a
simplified dial plan for outbound dialing using a
single universal prefix. Using the dial plan, the
gateway automatically detects the capabilities
received in the Setup message from the IP
endpoint and sets the same bit rate for the ISDN
(or serial interface) side of the call.
