LifeSize Gateway series consists of the following products:
Gateway-PRI (see About the Gateway-PRI) Gateway-Serial (see About the Gateway-Serial)
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.
The Gateway-Serial supports multimedia conferencing over IP by translating
between H.323 and serial protocols. With the help of an Imux, the LifeSize
Gateway can also translate between H.323 and H.320 protocols.
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.

FEATURES
Table 1-1 lists the major features of the LifeSize Gateway.
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
T.120 data collaboration The LifeSize Gateway supports data transfers in calls

About Gateway Features
Table 1-1 Gateway Feature Summary (continued)
Feature Description
Dial plan The LifeSize Gateway supports a simplif ied dial plan for
outbound dialing using a single universal prefix. Using
the dial plan, the LifeSize 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 LifeSize 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
Gateway-Serial supports DID in DCE mode
only.
Internal and External Interactive Voice
Response (IVR)
TCS4
Default extension
Access control The LifeSize Gateway features password-controlled
access to the LifeSize Gateway interface. Up to ten
different administrator ac cess profiles can be defined for
the LifeSize Gateway.
DTMF translation The LifeSize 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 LifeSize Gateway supports H.239 standards-based
dual video and T ANDBERG DuoV ideo technology. Dual
video streams enable a screen to carry video images from
one source while simultaneously displaying images from
a second source.
Functionality 3
Page 12
About Gateway Features
Table 1-1 Gateway Feature Summary (continued)
Feature Description
Conceal caller ID The LifeSize 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 LifeSize Gateway H.323 fast start feature enables
endpoints to join a voice conference in the LifeSize
Gateway more quickly.
ISDN rollover (available in
Gateway-PRI only)
The LifeSize Gateway features ISDN rollover. In this
feature, the LifeSize 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 Gateway-PRI
only)
The LifeSize 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 LifeSize 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 LifeSize Gateway re-registers to
the gatekeeper when the ISDN connection is restored.
Downspeeding The LifeSize Gateway features downspeeding
functionality. In the downspeeding feature, the LifeSize
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 LifeSize Gateway
supports downspeeding at call setup and in mid-call.
Multiple trap server support The LifeSize Gateway supports up to three SNMP trap
4 LifeSize Gateway Installation Guide
servers.

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 LifeSize Gateway supports the H.243 protocol in
ISDN-to-IP calls and in IP-to-ISDN calls. The LifeSize
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 LifeSize Gateway supports connectivity to the IP
network through a gatekeeper, or directly to a peer
device.
IP network connections The LifeSize 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.

ABOUT MULTIMEDIA CONFERENCING
The LifeSize Gateway-PRI enables H.323 endpoints on the IP network to
communicate with an H.320 terminal, an ISDN phone, or a regular phone on a
circuit-switched public network without having to connect directly to these
networks. The LifeSize Gateway allows all IP network terminals to support
video conferences without connecting every desktop computer to an ISDN line
(see Figure 1-1).

ABOUT MULTIPOINT CONFERENCING
The LifeSize Gateway-PRI 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) (see Figure 1-2).
Figure 1-2 Point-to-Point Conferencing through the Gateway
T ogether with the LifeSize Multipoint, the LifeSize Gateway-PRI enables 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 LifeSize Gateway, or be invited into
the conference by one of the participating IP endpoints. In either case, the
LifeSize Gateway connects the ISDN terminal to the LifeSize Multipoint,
enabling it to participate in the multipoint conference.

ABOUT GATEWAY
CALL BANDWIDTH
VERHEAD
O
Note Enabling ISDN-to-IP DTMF detection in the Gateway-PRI for video calls
reduces the number of supported calls by half.
According to the H.320 standard, the available bandwidth allocated to a call at
any given bit rate will always be slightly less than the stated maximum for the
following reasons:
All stated maximum call bandwidths include provision for control,
audio, video, and data traffic.
Video traffic on the ISDN side contains additional bits for error
correction purposes which also consume bandwidth. V id eo traff ic on
the IP side does not include this additional load.
Opening an audio channel further reduces the bandwidth available to
the video traffic.
Functionality 15
Page 24
About LifeSize Gateway Functionality
For example, a call at 384 Kbps actually has only 363 Kbps available to it.
Control and error correction account for the remaining 21 Kbps.
RESOURCE ALLOCATION ACROSS E1/T1 LINES
ABOUT PEER-TO-PEER
ONNECTIVITY
C
The LifeSize Gateway can allocate bandwidth resources to calls across separate
E1 or T1 connections to maximize bandwidth capacity in cases where there is
not enough capacity for a call on a single E1 or T1 connection, but where
sufficient capacity does exist when remaining capacity on both E1/T1 lines is
combined.
For example, a LifeSize Gateway using two T1 lines can support three 6B calls
on each T1 line, with 320 Kbps spare capacity per line:
Each T1 line provides 23 B channels.
Each B channel supports 64 Kbps
Each T1 line supports 23 x 64 = 1472 Kbps
Each 6B call requires 6 x 64 = 384 Kbps
Each T1 line supports 1472/384 = 3 6B calls + 320 Kbps spare
The LifeSize Gateway processes an additional 6B call requiring a further 384
Kbps by taking bandwidth resources from each of the two T1 lines, both of
which have 320 Kbps available. In this way, the LifeSize Gateway spreads the
call over both T1 lines.
The LifeSize Gateway supports the following types of connectivity to the IP
network
Through a gatekeeper
Directly to a peer device such without the need for a gatekeeper.
