lists the major features of the Cisco Unified Videoconferencing 3500 Gateway.
Description
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.
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.
The gateway features Simple Network Management Protocol (SNMP)
management that supports all aspects of monitoring, diagnostics, configuration,
and trapping.
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.
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.
The gateway supports data transfers in calls between ISDN and IP by using high
speed T.120 in HMLP and VarMLP formats.
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.
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.
The gateway dial plan supports these direct dialing and call routing facilities:
Direct Inward Dialing (DID)
•
Multiple Subscriber Network (MSN)
–
Q.931 Sub-addressing Information Element
–
Internal and External Interactive Voice Response (IVR)
TCS4
•
Default extension
•
The gateway features password-controlled access to the gateway interface. You
can define up to ten different administrator access profiles for the gateway.
The gateway supports translation between in-band Dual Tone Multi-Frequency
(DTMF) signals (on the ISDN side) and out-of-band H.245 messages (on the IP
side). DTMF translation occurs for voice and video calls.
