Networks (ISDN).

Mitel Networks 5760 VCA User’s Guide 1-1

Chapter 1 Welcome to the 5760 Video Conference Appliance

1.2 5760 VCA Features

The 5760 VCA provides several distinctive attributes and features which makes it
an ideal solution for many group videoconferencing environments:

! Superior video and audio streaming quality

The 5760 VCA includes award-winning technology and solutions for
maintaining high quality during video, audio and control transmissions. It
supports H.261 and H.263 video transmission as well as G.711, G.722 and
G.728 audio transmission. Features such as Automatic Buffering, Automatic
Lip Synch Enabling, Acoustic Echo Cancellation (AEC), Automatic Gain
Control (AGC) and Automatic Noise Suppression (ANS) provide superior
performance.

! 5700 Voice First Application Support

Mitel Networks 5700 Voice First Application (5700 VFA) provides
centralized management of an organization’s videoconferencing network. If
the 5760 VCA logs into an 5700 VFA server, it receives gatekeeper services,
bandwidth management, remote call initiations, and telephony functions, such
as call forwarding, call pickup, call transfer, ad-hoc videoconferencing, and IP­to-ISDN connection through a gateway.

When the 5700 VFA is connected to a 3300 Integrated Communications
Platform (ICP), users with video endpoints at their desktop can add video to an
audio call by simply pressing a key on a 5020/5220 IP Phone.

! Quality of Service (QoS)

PacketAssist™ Architecture preserves optimum quality of your
videoconference according to available bandwidth and network traffic. The
5760 VCA applies mechanisms such as IP Precedence to prioritize the video,
audio and control bits, and DiffServ to transfer packets according to the 5760
VCA’s specific needs.

! Participation in Interactive Multicast

Using Mitel Networks Interactive Multicast, all parties in the videoconference
see and hear the same video, audio, and data sharing. 5760 VCA users may
temporarily receive the floor, in which their video and audio are seen by the
other parties until the floor returns to the session’s controller (Chair).

! H.323 and H.320 Multipoint Videoconferencing

In multipoint videoconferencing through a Multipoint Control Unit (MCU),
the parties may see and switch among the video of several participants,
through functions such as Continuous Presence and Voice-Activated
Switching.

Calling Through Gateways

On certain occasions, you may need to videoconference with parties who are
connected to different networks or telephone exchanges. As noted earlier in this
User’s Guide, you can directly call any ISDN number, if you dial the correct
telephony prefixes (long distance code, country code, area code, etc.).

You can also call a system that is outside of your LAN. When you dial a remote IP
address, the router that you designate as your default gateway (see “LAN
Connection and Registration” on page 4-4) takes the call and routes it to the
destination.

However, at some point, you may be unable to take advantage of one of the
communication modes (IP or ISDN). If this happens, you can still meet with your
contacts by calling through an H.323/H.320 (IP/ISDN) Gateway.

! If your LAN connection is down, you can call the Gateway through your ISDN

lines and reach H.323 systems (IP addresses and other LAN-based addresses).

! If your ISDN lines are down, you can call the Gateway through your LAN

connection and reach H.320 systems (ISDN numbers).

Before attempting a Gateway call, ask the system administrator to give you
the calling syntax. The syntax includes a service access number and, in some
cases, a variation of punctuation signs.

" To call through a Gateway

1. Open the Manual Dial dialog (see “Starting a Videoconference from the
Manual Dialer” on page 2-7) and dial [service access number][ISDN

2. Set the required Bandwidth or use the default bandwidth.

3. Press <Dial>.

The gateway’s gatekeeper receives the call. It recognizes the syntax that
the system administrator instructed you to enter, and it passes the call onto
the Gateway. You must be registered with a Gatekeeper to reach a
Gateway (see “H.323 Network Registration and Properties” on page 4-5
for details).

The Gateway calls the destination, and when it receives an answer, it
begins the videoconference, continuously translating between H.320
(ISDN) and H.323 (IP).

H.323 Network Registration and Properties

H.323 is the standard for video, audio, and data streaming over IP networks. In the
H.323 tab, define how the 5760 VCA handles these functions within its LAN
environment. These properties include:

! H.323 Management - registration of the 5760 VCA with a remote H.323

management and service provider

! Automatic Video Transmission Adjustment - automatic preservation of

optimum transmission, in response to changing network conditions

! Setting Quality of Service (QoS) Levels - control of the Quality of Service

that will be used for transmitting packets from the 5760 VCA.

H.323 Management

Many H.323 networks include devices such as the 5700 VFA or a gatekeeper,
which provide important management functions and provision of communication
services to large numbers of users within defined zones on a LAN or WAN. The
5760 VCA supports registration with the 5700 VFA and with third-party H.323
Gatekeepers.

NAT IP If your organization uses NAT (Network Address

Translation) when communicating with parties in
another LAN or WAN, type the external address for
your 5760 VCA device.

NAT helps protect a LAN from exposure to
unwanted traffic by providing one single external
address to remote users. NAT uses a system of local
and external addresses to hide a LAN's users from
other networks. A NAT server translates local parties'
addresses to an external address, which is then used
to identify the local party to remote parties.
Therefore, remote parties use this external address to
call the local party, without knowing its actual local
address.

Setting Quality of Service (QoS) Levels

The PacketAssist™ Architecture simplifies Video over IP bandwidth management
and delivers true Quality of Service (QoS) for IP networks. PacketAssist
automatically adapts video meeting transmissions to current network conditions,
while ensuring optimal video and audio performance.

The QoS Properties dialog box contains properties for controlling the type of
Quality of Service that will be used for transmitting packets from the 5760 VCA. A
password is required to open this dialog box, and we recommend that only system
administrators with knowledge of QoS make any changes, if required.

CAUTION The Quality of Service defaults should be changed only by a

system administrator.

" To set Quality of Service options

1. When the H.323 tab of the Network dialog box is open, press the green
QoS SoftKey.

Press the green QoS SoftKey to view and
change Quality of Service properties.

2. Set QoS properties as follows (see tables on page 4-12):

Priority Type Select the type of QoS priority used for transmitting

packets during heavy network congestion
conditions.

! No Priority - network transfers packets in a

normal Best-Effort method (First In, First Out,
or FIFO).

! IP Precedence - network gives priority to

video, audio, control bits according to the eight
levels of IP precedence.

! Diffserv - network transfers packets according

to specific differentiated services priority
levels.

Chapter 4 Network Configuration

Priority Values For Video, Audio, and RTCP (Real Time Control

Protocol) Priority, enter an appropriate priority
level. According to their priority levels, bits are
queued for forwarding by QoS-supporting routers.

The priority levels vary, depending on whether the
selected Priority Type is IP Precedence or
Diffserv.

3. To return to the default QoS values, press the red DFLT QoS SoftKey.

4. Press <OK> to save the QoS settings and close the dialog box.

For best results, it is recommended that RTCP packets receive the highest
priority, to ensure that QoS features continue to operate during the entire
call.

Audio packets should receive a higher priority than video packets, as a
meeting can continue without video, but not without audio.

6VIDEO OVER IP

Mitel Networks provides quality videoconferencing products which conform to the
H.323 recommendation for network communications over IP, set by the ITU-T.

This chapter summarizes the H.323 Recommendation, its equipment and services,
and describes the roles and uses of the different components of an H.323 Video
over IP solution.

6.1 H.323 Recommendation

Recommendation H.323 describes equipment that provides services for packet­based multimedia communications.

Equipment

H.323 equipment includes:

• Conferencing endpoints

• Gateways

• Gatekeepers

• Multipoint Conference Units (MCUs).

Services

The main objective is for people to conference with each other, no matter how far
apart they are physically located, or how differently their systems were designed by
their manufacturers. The H.323 Recommendation details how the components of a
Video over IP system cooperate to fulfill this task.

Mitel Networks 5760 VCA User’s Guide 6-1

Chapter 6 Video over IP

Packet Based

In a packet-based network, multimedia streams are broken into packets, sent over
the network through various routes, and reassembled into streams when they reach
their destination. Packet-based bandwidth is dynamic—it depends on how busy and
capable the network routes are at the time of the call.

IP (Internet Protocol) is a set of rules (a protocol) governing how packets are sent
and received over a packet-based network.

Packet-based networking greatly differs from circuit-switched networking (used
for ISDN lines), which opens a dedicated route by turning on switches along the
way to make a permanent circuit between the caller and the party being called for
the duration of the call. ISDN bandwidth is fixed—other calls are not allowed to
use the same circuits until the call has ended.

Although ISDN networking offers a fixed bandwidth, and therefore a Quality of
Service unavailable to IP, there are certain advantages to packet-based networking:

! Packet-based networks use the existing network and infrastructure. This

means lower costs for setup and maintenance. ISDN lines are expensive to
buy, install, manage and service.

! While packet-based endpoints connect to the existing network at the

office, ISDN-based endpoints require separate installations for each.

! Only IP can integrate interactive and streaming video into a single

solution, such as VCON’s Interactive Multicast.

6.2 Conferencing Systems

Starting with the simplest of Video over IP scenarios, we have two conferencing
systems (such as the Mitel Networks 5750 Desktop Video Appliance) and an IP­network segment.

6.3 Multipoint Conference Units (MCUs)

H.323 conferencing systems can communicate with each other in point-to-point
conferences, but if we add a Multipoint Conference Unit (MCU) to the LAN,
several users can join in a single video meeting. An MCU is a device that
centralizes the connections and characteristics of a multipoint video meeting.

To join multipoint meetings through an MCU, a system must be registered with a
gatekeeper which is registered with the same MCU. A system enters a meeting by
either calling the MCU (dial its IP address, as you would any endpoint) or
answering a call from the MCU.

5750 DVA Standard

MCU

Desktop Conferencing
System (Mitel Networks/non­Mitel Networks)

During the call, participants will see either
the person currently talking (Voice­Activated Switching) or a composite screen
of all active participants (Continuous
Presence).

When the 5700 VFA is connected to a 3300 ICP (Voice First Mode),
videoconferences are always in Continuous Presence mode.

For non-Mitel Networks endpoints, the MCU is the only available solution for fully
interactive multiparty video meetings.

Mitel Networks offers an affordable software solution for multiparty conferences:
Interactive Multicast. If your system does not support it, and you want to add it,
contact your local Mitel Networks distributor. See Chapter 7, “Multi-Party
Conferencing with Interactive Multicast” for more information.

6.4 Gatekeepers

A Gatekeeper is a software application that makes network conferencing simpler. It
provides management services and user-friendly features for dialing other systems.

Every conferencing system that registers with the Gatekeeper provides its User
Number (also called an E.164 Number) and a User Name (also called an H.323
Alias). The Gatekeeper keeps a database so it can map between the IP address, the
User Number and the User Name of each system. Therefore, you can dial these
numbers or names instead of IP addresses.

Example Definition

User Number

User Name

122.29.65.203 Dynamic address assigned by a network server.

290 User selected number, such as a phone number.

Boardroom User selected name, or the name of the system.

User Numbers and Names are static. They do not change, as long as a system
remains registered with the same Gatekeeper. IP addresses are usually dynamic;
they may change without notification. Ask your system administrator for your User
Number and Name.

6-6 Mitel Networks 5760 VCA User’s Guide

Chapter 6 Video over IP

Gatekeepers also provide access control, which means that you cannot
communicate with non-registered systems. Fortunately, Gatekeeper zones are not
limited to LAN segments; they can connect international WANs. If you want to call
someone who is registered with another Gatekeeper, ask the system administrators
to set the Gatekeepers as neighbors. Neighboring Gatekeepers share databases;
their endpoints can contact each other. Make sure that your conferencing contacts
are registered either with your Gatekeeper, or with one that neighbors it.

6.5 Gateways

A Gateway enables you to call any standard conferencing system, whether it’s an
IP or an ISDN endpoint.

ISDN and IP endpoints cannot directly communicate with each other. Therefore, a
Gateway is used to enable communication between H.323 (IP) and H.320 (ISDN)
systems.

To call an ISDN number from an IP endpoint, you dial the Gateway’s service
number and then the ISDN number. Consult with your system administrator.

7MULTI-PARTY CONFERENCING WITH

I

NTERACTIVE MULTICAST

This section does not apply when the 5700 VFA is connected to a 3300 ICP
(Voice First Mode).

Interactive Multicast for multi-party videoconferencing is a software alternative to
the expensive MCU (see Chapter 8, “Multi-Party Videoconferencing Through an
MCU”, for more information on MCUs). Interactive Multicast uses bandwidth
more efficiently than an MCU does, and it does not limit the number of users in a
session or the number of sessions per license; most MCUs do.

During an Interactive Multicast, identical video streams, audio streams, and data
application sharing packets are sent from one party to multiple parties. The
initiating party (Chair) calls one or more parties (Participants) at the start of the
conference and controls its progression. All parties receive identical transmissions.

Many Mitel Networks products provide the capability to carry out Interactive
Multicast video meetings over a Local Area Network (LAN), in which the Chair
and all Participants may be seen and heard during the duration of the meeting. The
5760 VCA IP can join an Interactive Multicast as a Participant—Participant
functions are available.

As a Participant, you may receive the floor, in which its video and audio is seen and
heard, respectively, by the other Participants and the Chair for a period of time. In
addition, you may send a text message, such as a question or comment, to the Chair
at any time.

Interactive Multicasts can proceed in the form of a lecture or demonstration, in
which Participants’ participation is restricted and controlled by the Chair, or as a
free discussion, in which everyone has the right to be seen and heard without the
need to receive permission from the Chair.
