About Gateway Features
About Gateway Features
Table 1-1 lists the major features of the Cisco Unified Videoconferencing 3500 Gateway.
Ta b l e 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 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
Access control The gateway features password-controlled access to the gateway interface. You
can define up to ten different administrator access profiles for the gateway.
DTMF translation 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.

Chapter 1 Functionality
About Gateway Features
Table 1-1 Gateway Feature Summary (continued)
Feature Description
Dual video The gateway supports H.239 standards-based dual video and TANDBERG
DuoVideo technology. Dual video streams enable a screen to carry video images
from one source while simultaneously displaying images from a second source.
Conceal caller ID The gateway supports a conceal caller ID feature that instructs the gatekeeper to
conceal the identity of the calling endpoint on the IP or ISDN network, whether
the presentation restricted feature is enabled or not.
H.323 fast start The gateway H.323 fast start feature enables endpoints to join a voice conference
in the gateway more quickly.
ISDN rollover (available in Cisco Unified
Videoconferencing
3527 PRI Gateway
only)
The gateway features ISDN rollover. In this feature, the gateway sends a “busy
out” channel request to the PSTN switch when the current PRI connection is left
with less than a predefined number of available B channels. The PSTN switch
“rolls over” to the next available gateway.
Network Specific Facility (available in
Cisco
Unified
Videoconferencing
3527 PRI Gateway
only)
The gateway provides support for Network Specific Facility Information
Elements (NSF IEs) which enable system administrators to specify to service
providers the equipment, service, or network through which they want a call
routed.
ISDN connection failure The gateway responds to ISDN connection failure events, by unregistering from
its gatekeeper. The gatekeeper is forced to send new IP-to-ISDN calls through a
different gateway, thus ensuring high call completion rates. The gateway
re-registers to the gatekeeper when the ISDN connection is restored.
Downspeeding The gateway features downspeeding functionality. In the downspeeding feature,
the gateway attempts to reconnect a disconnected video call either at a lower
bandwidth or as a voice call. Downspeeding contributes to a higher percentage of
call completion on the network. The gateway supports downspeeding at call setup
and in mid-call.
Multiple trap server support The gateway supports up to three SNMP trap servers.
H.239 support The gateway supports the H.239 protocol in ISDN-to-IP calls and in IP-to-ISDN
calls.
Encryption support The gateway supports H.235-compliant AES 128 encryption for calls over IP
networks, and H.233 and H.234-compliant AES 128 encryption for calls over
ISDN networks.
H.243 Conference Control support The gateway supports the H.243 protocol in ISDN-to-IP calls and in IP-to-ISDN
calls. The gateway identifies the protocol version that an IP endpoint uses and
sends H.239 capabilities only to those endpoints working with protocol version
4.0 or later.
Peer-to-peer connectivity The gateway supports connectivity to the IP network through a gatekeeper, or
directly to a peer device such as Cisco
Unified Communications Manager.
IP network connections The gateway has one 10/100Base-T Ethernet IP port (on the front panel) and
connects to an IP segment through a direct connection to a network switch.

The Cisco BRI gateway enables direct video, voice, and data communication between an H.320 (ISDN)
terminal and H.323 (IP) terminals at bandwidths of up to 512 Kbps (4 BRI lines) using bonding mode 1
(see
Figure 1-2).
The Cisco PRI gateway enables direct video, voice, and data communication between an H.320 (ISDN)
terminal and H.323 (IP) terminals at bandwidths of up to 1472 Kbps (23B bonding for T1) and up to
1920 Kbps (30B bonding for E1).
Figure 1-2 Point-to-Point Conferencing through the Gateway
About Cisco Unified Videoconferencing 3500 Gateway Applications and Topologies
About Multipoint Conferencing
Together with the Cisco MCU, the Cisco PRI gateway and BRI gateway enable H.320 ISDN terminals
to participate in a mixed ISDN-IP multipoint multimedia conference with IP network endpoints (see
Figure 1-3).
For example, when an H.320 ISDN terminal wants to participate in a multipoint conference with H.323
IP endpoints, the H.320 ISDN terminal can either join the multipoint conference by dialing to the
gateway, or be invited into the conference by one of the participating IP endpoints. In either case, the
gateway connects the ISDN terminal to the Cisco MCU, enabling it to participate in the multipoint
conference.
