Table 1-1lists 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	The gateway features the gateway interface. This is a web interface used
management	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	The gateway supports load balancing on the network by communicating
balancing	with a gatekeeper through H.323 RAI (Resource Available
	Indication)/RAC (Resource Available Confirmation) messages.
T.120 data	The gateway supports data transfers in calls between ISDN and IP by
collaboration	using high speed T.120 in HMLP and VarMLP formats.
Quality of service	The gateway features configurable coding of media packets to achieve
(QoS)	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	The gateway dial plan supports the following direct dialing and call
routing	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
