About Cisco Unified Videoconferencing 3545 Gateway Products

Cisco Unified Videoconferencing 3545 Gateway series consists of the following products:

•Cisco Unified Videoconferencing 3545 PRI Gateway (see the “About the Cisco Unified

Videoconferencing 3545 PRI Gateway”)

•Cisco Unified Videoconferencing 3545 Serial Gateway (see the “About the Cisco Unified

Videoconferencing 3545 Serial Gateway”)

About the Cisco Unified Videoconferencing 3545 PRI Gateway

The Cisco Unified Videoconferencing 3545 PRI Gateway enables audio, video, and data communication

between H.320 endpoints that connect through ISDN, and H.323 endpoints that connect through a

packet-based network. For voice-over-IP, the gateway enables PSTN voice callers to connect from the

ISDN network to IP voice callers. The CISCO UNIFIED VIDEOCONFERENCING 3545 PRI

GATEWAY supports two PRI ISDN ports.

About the Cisco Unified Videoconferencing 3545 Serial Gateway

The Cisco Unified Videoconferencing 3545 Serial Gateway supports multimedia conferencing over IP

by translating between H.323 and serial protocols. With the help of a V.35 Adtran Imux, the gateway can

also translate between H.323 and H.320 protocols.

The gateway offers a serial leg for multimedia conferencing over IP by providing an interface for legacy

endpoints with serial interfaces, encryption/decryption devices, satellite networks and leased line

services.

Chapter 1 Functionality

About Gateway Features

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

Chapter 1 Functionality

About Gateway Features

Access control The gateway features password-controlled access to the gateway interface.

Up to ten different administrator access profiles can be defined 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.

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.

Hot swap The gateway features hot swap functionality that you can use to remove

and replace gateway cards under power.

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

3545 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

3545 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.

Chapter 1 Functionality

About Gateway Features

Table 1-2 lists features for specific Cisco gateways.

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.

channels.

The gateway automatically performs

A-Law G.711-to-µ-Law G.711

translation between the IP and ISDN

sides if needed.

Note When your Cisco unit

includes both a gateway and

a MCU, G.728 transcoding is

supported on the MCU only.
