ABOUT THE

GATEWAY-PRI The Gateway-PRI 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-PRI enables

PSTN voice callers to connect from the ISDN network to IP voice callers. The

Gateway-PRI supports two PRI ISDN ports.

ABOUT THE

GATEWAY-SERIAL The Gateway-Serial supports multimedia conferencing over IP by translating

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

LifeSize Gateway can also translate between H.323 and H.320 protocols.

About Gateway Features

The LifeSize 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.

ABOUT GATEWAY

FEATURES Table 1-1 lists the major features of the LifeSize Gateways.

Table 1-1 Gateway Feature Summary

Feature Description

Interoperability The LifeSize 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 LifeSize Gateway features the LifeSize Gateway

interface. This is a web interface used to configure and

monitor the LifeSize Gateway. You can view and modify

all aspects of the LifeSize Gateway configuration from a

remote location using a Java-enabled web browser.

SNMP management The LifeSize Gateway features Simple Network

Management Protocol (SNMP) management that

supports all aspects of monitoring, diagnostics,

configuration, and trapping.

Diagnostics The LifeSize 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

LifeSize Gateway interface, Telnet, SNMP, or a serial

port.

Network load balancing The LifeSize 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 LifeSize Gateway supports data transfers in calls

between ISDN and IP by using high speed T.120 in

HMLP and VarMLP formats.
