Table 1-1 lists the major features of the Cisco Unified Videoconferencing 3545 Gateway.
Table 1-1 Gateway Feature Summary
Feature Description
Interoperability The 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 gateway features the gateway interface. This is a web interface used
to configure and monitor the 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 gateway features Simple Network Management Protocol (SNMP)
management that supports all aspects of monitoring, diagnostics,
configuration, and trapping.
Diagnostics The 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 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 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 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 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.
Direct dialing and call
routing The gateway dial plan supports the following direct dialing and call
routing facilities:
• Direct Inward Dialing (DID)
• Multiple Subscriber Network (MSN)
• Q.931 Sub-addressing Information Element
Cisco Unified Videoconferencing 3545 Serial Gateway supports DID in
DCE mode only.
• Internal and External Interactive Voice Response (IVR)
• TCS4
• Default extension
