The MGC Web Server Manager application is the user interface to the
MGC Web Server. It allows the user to communicate via the Web Server
with the MCUs. It provides dat abase access via the Web pages and manages
the Web site that contains the reservation pages.
MGC Web Server Architecture
The MGC Web site is a location on a computer network. It contains
reservation information in the form of pages that can be accessed by users
logging into the site with browser applications such as Microsoft Internet
Explorer or Netscape Communicator.
The Internet client connects to the Web site located on the Internet server
and, via the MGC Web Server, gains access to the reservation pages, the
database tables, and the MCU that runs the conference.

The Network Server
The network server contains the following applications:
•Database Server (SQL server or the Access application): enables
access to various database tables, such as MCU list, Users list, and
Groups
•Internet Information Services (IIS) Server: runs the Web pages and
enables users to access these pages via the Internet and make
conference reservations
•MGC Web Server: communicates with the IIS server, the Database
server, and the MCUs. This is the core of all the data exchange
performed in the Web site. Using the MGC Web Server Manager
application, users manage the MCUs connected to the Server, add
database accesses via the Web pages, and manage the reservation
pages.

MGC Web Server Manager Basics
The MGC Web Server Manager enables users access to the database. The
database is divided into two modules:
•Administrative tables – the configuration tables that enable the
administrator and users who have the right to modify these tables to
define MCUs, system Defaults, Labels, Permissions, Users and Groups.
In addition, the administrator can perform maintenance and
configuration tasks relating to the database itse lf. The configuration is
performed through the MGC Web Server Manager application.
•User T ables – This m odule is divided into two segm ents: P artici pants &
Conference Templates and Master Templates. The Participants an d
Conference T emplates segmen t includes the Participant and Conference
templates that are organized in Groups. Users can only man age
templates assigned to Groups to which they have access rights. The
Groups and their access rights are defined in the MGC Web Server
Manager module. The Master Templates segment includes Master
templates that are organized in Master Template Groups (usually other
than the Participants and Conference Template Groups).

Important!
When both the MGC WebCommander and the MGC Manager applications
use the same database, the administrator tables defined in the MGC Web
Server Manager will apply to the MGC Database Manager and vice versa.
Therefore, the various tables may include parameters that apply only to the
WebCommander and others that will apply only to the MGC Manager. Users
may access the database via the MGC Web Server Manager or the MGC
Database Manager and perform changes in the administrator tables. These
changes will apply to both applications.
This manual describes the various Web Server Manager tables and their
configurations.

parameters. The default sets may be stored in a centralized database or in a
local database.
When the WebCommander user defines a new conference (reservation, On
Going or a template) or a new participant, each parameters displays the
default value taken from the active Defaults set. It minimizes the need to
define all the parameters and it allows users to modify specific parameters,
as needed.
Default sets may be defined for the following categories:
•Conference Defaults – A list of all the conference parameters.
•Participant Defaults – A list of all the participant parameters.
•MGC Manager Defaults – General system parameters that apply only
to the MGC Manager. These parameters can also be defined in the
MGC Web Server if the same database is used by both applications.

In a Video Switching conference, you must select
the highest transfer rate common to all
participants. For example, if two part icipants can
connect at a transfer rate of 384 Kbps and one
participant can connect at a transfer rate of 128
Kbps, set the Line Rate to 2B or 128 Kbps (2B in
Bonding mode). In a conference with participants
from mixed networks (ISDN and H.323), the line
rate defined for the ISDN partic ipant is the line rat e
that will be used for the H .323 p a rtic ipant. The line
rate currently supported for H.323 is E1. In high
rates, the capacity of the H.323 Network card
changes. For more details, see the MGC
Hardware and Installation Guide, Chapter 4.
In Transcoding and Continuous Presence
conferences, the line ra te is defi ned for eac h of the
participants se parately. The conference line rat e
apply only to those participants whose Line Rate
was set to Auto. In such a case, set the conference
line rate to the highe st transfer r ate possible by the
endpoints connecting in Auto mode. Maximum
transfer rate in Transcoding and Continuous
Presence modes is 1920 Kbps (E1). In Software Continuous Presence (SWCP) the Line Rate is set
for conferences and represents the transmission
rate from the MCU to the endpoint (combined
video rate and audio rate). For more details
regarding the Line Rate settings for Software CP
conferences, see MGC Manager User’s Guide Volume II, Chapter 1.
Line Rate (con’t)Note: The high line rate transmission is enabled
with the standard vide o c ard (v ers io n 1 .43 an d u p)
or with the Video+ card. The line rate of incoming
ISDN/H.323 calls can be automatically detected
and the participant can be connected according to
his/her capabilities, without prior setting of the
endpoint’s line rate during conference setup. In
such a case, the conference Line Rate is the
maximum rate for the participant connection. For
more details, see MGC Manager User’s Guide
Volume II, Chapter 1.
Audio AlgSelect the preferred audio al gorithm. The availa ble
audio algorithms are: 8 (G.729/G.723.1), 16

G.711), 56 (G.722/G.711), or 56 (G.711).
Siren 7 and Siren1 4 are Pol ycom prop riet ary audio
algorithms. Siren14 can be used only if the MCU is
configured to Wideband.
To support Siren14 , The system must include:
•The appropriate Polycom settings to support
Siren14.
•An Audio+ card must be installed in the MCU.
If the conference is set to Siren14 and the
endpoints cannot connect in Siren14, G.722.1 is
used instead.
The option 8 (G.729/G. 723.1) is available on ly in IP
Only (VOIP and video) conferences.
In Video Switching conferences, all of the
participants must use the same audio algorithm.
Participants with endpoints that do not supp ort th e

new conferences. If Silence IT is not enabled in
the IVR the conference definition is rejected.
Conference On
Port
Select the Conference On Port settin g, when you
want conferences to use a singl e vi deo port on the
MCU. It enables the selection of a video layout for
the conference, but all the conference participants
see the same layout and the same participants,
that is, also the speaker can see himself/herself.
Personal layout selection is not available in this
mode and the video quality is determined by the
highest common video parameters and video line
rate.
The following modes are not available for
conferences set to Conference On Port.
•Lecture Mode
•Personal Layout
•Cascading
For more information, see MGC WebCommander
User’s Guide, Chapter 7.
T.120 RateSelect the desired T.120 data transfer rate. The
lower the rate the slower the transfer rate and the
response time.
The same T.120 rate must be set for all the
conference participants. The highest rate common
to all participants should be selected.
Select None to disable the T.120 mode.
If the conference Line Rate is set to 2B, the
following T.120 rates are available for selection:
•MLP - 6.4k

LSD mode.
Video SessionSele ct the app ropriate Video Session:
VideoSwitching - To set a conference in which all
the participants use the same video and audio
formats, by setting the communication p aram eters
to the common capabilities. Whenever a
participant starts to speak, he/she appears on all
screens as the conference is a voice activated
video switching con ference. All participants view
the participant who is the speaker. Up to 16 or 30
participant s (if at least one Audio Brid ge i s set to 1/
30) can take part in a Video Switching conference
using the standard Audio card. Up to 100
participants a t 128Kbps can take part in a
conference running on the Audio+ card.
Transcoding - To set a conference in which
participants use different video, audio and data
formats, maintaining the highest video and audio
capability each particip ant can achiev e with his/her
codec. Like Video Switching, the current speaker
is displayed on all terminals.
ContinuousPresence (CP) - A Continuous
Presence conference is a conference in which
several partici pants can be viewed simu ltaneous ly .
Each participant uses their own endpoint’s
capabilities, thus maintaining the highest video,
audio and data capability that can be achieved. If
the number of participants is less than or equal to
the number of participants displayed, each
participant can see all of the other participants.
When selecting Continuous Presence the
following layout options are available:
•Classic
•Quad Views
•Software
Classic - Classic Continuous Presence used the
standard Video card. 21 video layouts are
available in this mode.
Quad Views - The Quad Vie ws mode req uir es the
Video+ card. It includes layouts for large video
conferences. This mode should be selected when
the conference includes 10 par tic pants or more.
Software - Software Continuous Presence is
implemented in IP ne twork s onl y and is a soft w are
solution that resembles the Continuous Presence
feature in terms of functionality, without using
video card resources. Software CP combines four
incoming QCIF streams with fixed video bitrate
from four different participants into one outgoing
CIF stream. In Software CP conferences only two
types of Video Layout formats are available: 2x1
and 2x2. If the conference includes less than 5
participants, one of the participant's layout
windows is grayed out.

Volume II, Chapter 1.
Pro-MotionPro-Motion is enabled only in the Video Switching
mode.
Pro-Motion is a video encoding mechanism that
improves the video quality in Video Switching
conferences, set to NTSC or PAL (4CIF)
resolution. Select either 50 Fields (PAL) or 60 Fields (NTSC).
Pro-Motion is sent t o th e e ndpoint at 60 Fields Per
Second (FPS) for NTSC and 50 FPS for PAL
systems. The interlaced video mechanism takes
two separate video frames and merges them into a
single frame.
Note:
When a conference is set to any Pro-Motion
option, endpoints sending a Pro-Motion video
resolution (for example, NTSC instead of PAL or
vice-versa) or that do not send a Pro-Motion
resolution, connect as Secondary (Audio Only).
Dual Stream ModeIn this mode, one of the endpoi nts s ends two v ideo
streams: Video and data. The video streams are
handled differently by the receiving endpoint. The
different streams may be shown on separate
screens.
Select one of the following options:
None - The Dual Video mode is unavailable. In
such a case Video Protocol is set to Auto.
H.239 and People+Content - H.239 and
People+Content are very similar in function, but
differ in the type of signaling us ed for each
protocol. People+Content is the Polyc om
proprietary protocol while H.239 is the industry
standard. When an endpoi nt can suppo rt both
H.239 and People+Content protocols, H.239 is
selected as the preferred communications
protocol.
In the Reservation Template Settings - Dual Stream mode drop down box, three H.239 People+Content (H.239/P+C) Video streaming
formats are available:
Graphics - for standard graphics
Hi-res Graphics - for high qualit y disp lay or h ighly
detailed graphics
Live Video - for video clips or li v e video display
128 Kbps is the minimum Line Rate setting for a
H.239/People+Content conference. When the
Content channel opens, the required bit r ate is
taken from the video channel bit rate, and may
affect the quality of the transmitted video quality.
The bit rate allocated to the Content channel
depends on the conference type and the
conference line rate, where the minimum is
64 Kbps, and increases i n multiple of 64 Kbps. The
bite rate allocation is dynamic and when the
Content channel closes, the video bit rate is
restored to its maximum.
People+Content in a Cascading conference is
enabled only for Video Switching IP Only
conferences, in a Star Cascaded topology.
H.239 and People+Content supports the following
features:
•Entry Queues
•Highest Common Phase 2
•H.264
•4CIF
•Encryption
•FECC (H.320 and H.323)
Limitations
•In Continuous Presence conferences -
Software and Quad View modes are disabled
•H.239 is not supported in:
•ISDN (H.320) calls
•H.320 Cascading confe rences
•MIH Cascading conferences
•Simple cascading conf ere nc es
•T.120 conferences
•Double Gateway configurations
Using this feature the People video s tream an d the
Content video stream are treated differently by the
endpoints. For more information, see
WebCommander User Guide Chapter 7, “Dual
Stream Mode” on page 7-11.
People and Content V0 - Polycom proprietary
technology that works mainly with PictureTel
endpoints. Content, Annex N, Annex P and Annex F are automatically checked by default.
DuoVideo - Dual Stream mode available with
T andberg endpoints in which one conference is set
as the video conference and the other as the
presentation conference. Select this option to
define the presentation conference.
Polycom Visual Concert PC/FX - Available with
Polycom Viewstation or Viewstati o n FX endpoints.
Select this option to enable the Visual Concert
option for the conference. Annexes can be
selected.
Video FormatCIF and QCIF are video formats used in video
conferencing systems. Video Format specifies the
data rate (in number of fr ames per seco nd) and
the resolution of each frame (number of lines in a
frame and the number of pixels in each line).
Video Format is enabled only in Video Switching
mode and when th e Video Protocol is set to H.261
or H.263.
CIF (Common Intermediate Format) - Each frame
contains 288 lines and 352 pixels per line. The
data rate is up to 30 frames per second (FPS)
QCIF (Quarter Common Intermediate Format) Each frame contains 144 lines and 176 pixels per
line (it is one-fourth the resolution of CIF).
This field is disabled if the Video Protocol field is
set to Auto.
•Using the H.261 protocol, you can selec t Auto ,
QCIF, or CIF.
Select Auto to allow the system to select the
video format for the conference according to
the partici pants' capabil ities and enable the
dynamic adjustment of the highest common
video reso lution. In such a case, the system
will connect all the participants in CIF format.
If one of th e participants' endpoints does not
support CIF, the conference video format will
change to QCIF for all the participants.
•Using the H.263 protocol, you can select one
of the following options : Auto, QCIF, CIF, 4CIF,
16CIF, VGA, SVGA, XGA and NTSC.
4CIF - High Quality 4 CIF video reso lution ava ilable
in Continuous Presence conferences running at
512 Kbps or higher line rates. In this mode, the
endpoints t ransmit CI F (or QCIF) and rece ive 4CIF
images from the MCU. In full screen layout (1x1),
endpoints that can send 4CIF images will also
receive and view 4CIF images from the MCU.
In 4CIF CP conferences, you can select the
Quality of the screen display depending on the
video transmission:
Sharpness - Optimized for details. The video
picture does not change frequently, but it includes
details that you want to display in higher
resolution. For example, when displaying still
images, presentations, or capturing people.
Motion - Optimized for motion. The video pictures
change frequently and display movement, for
example, a sporting event where the camera is
moved around, people moving around, etc.
NTSC (National Television Standards Committee)
- Each frame contains 525 lines and up to 16
million colors.
VGA (Variable Graphics Array) - 640 x 480
resolution
SVGA (Super Variable Graphics Array) - 800 x 600
pixel resolution
XGA (eXtend ed Graphics Array) - 1024 x 768 pix el
resolution
VGA, SVGA, XGA and NTSC options are
important for displa ying conten t when sele cting the
People and Content mode. Typically the People
resolution is CIF with a frame rate of up to 30
frames per second, w hil e th e Con tent res ol uti on is
VGA, SVGA, XGA or NTSC.
Switching mode and the V id eo Protocol is set to H.261 or H.263. If you have selected QCIF, CIF,
4CIF, 16CIF, VGA, SVGA, XGA, or NTSC, select
the number of fram es per sec ond rate to defin e the
quality of the video transmission. 7.5 indicates a
video quality of lower than 30 frames per second.
Select Auto to enable the dynamic adjustment of
the conference frame rate to the highest common
rate.
This field is disabled if the Video Form at field is set
to Auto.
Video ProtocolThe Video Protocol, Video Format and QCIF
Frame Rate are parameters that determine the
highest common video used by all the conference
participants. The Video Protocol determ ine s the
video compression standard used by the
endpoints.
Auto - Select this option to let the system
automatically select the appropriate compression
method and enable the dy nam ic ad jus tm en t of the
highest common video algorithm. In such a case,
when a participant leaves the conference, the
MCU adjusts the common video to the highest
level for the remaining connected participants.
This setting overrides the Video Protocol se ttin g s
in the Participants Properties - Advanced dialog
box as the dynamic mode settings are forced by
the MCU.
H261 - The video compression standard
mandatory to all endpoints.
H263 - A compression standard that provides
improved video quality at a line rate lowe r than 384
Kbps. This standard is not supported by all
endpoints. If H.263 is selected in Video Switching
conferences, all participants must be connected
using this protocol. Participants whose endpoint
does not support H.263 are connected as
Secondary.
H264* - H.264* incorporates DCT (H.263)
compression principles, but is provided at half the
bit rate. H.264* pro vi des C IF/ 4C IF vid eo us ing lo w
bit rates and implements a fixed video rate when
the video stream of the endpoint becomes active
("people "). The endpoint that supports H.264* is
iPower.
H264 - The H.264 standard provides better
compression of video images in lower line rate
connections and is part of the Highest Common
mechanism in Video Switching conferences.
When the conference line rate is up to 384Kbps,
and the Video Protocol i s set to Auto (in bo th VSW
and CP conferences) the system tries to connect
the participant using H.264 video protocol first.
Only if the endpoint does not support H.264, the
system tries to connec t the pa rticip ant using H. 263
or H.261.
When H.264 is selected, the Video Format is
disabled and set to Auto.
Notes:
•When selecting the H.261 or H.263, the system
regards it as a fixed format and disables the
dynamic adjustment of the highest common
video.
•The dynamic adjustment of the video protocol
applies only to H.320 (ISDN) participants.
The dynamic adjustment of the video protoc ol
supports only 30 frames per sec ond in CIF forma t.
All other H.263 capabilities are disabled.
AnnexesAnnexes are additions to the Video Format when
using H.263 Video Protocol, increasing the quality
of the video display.
Annexes N, P and F are enabled only when you
are in Video Switching mode and the Video Protocol is set to H.263. The Vide o Format ma y be
set to QCIF, CIF, 4CIF, 16CIF, VGA, SVGA, XGA,
or NTSC.
When Video Format is set to Auto, the system
selects the appropriate annexes according to the
endpoint's capabilities. The annexes are required
in the Dual Stream mode, but may also be
selected independently.
•Annex F - Advanced Prediction Mode. This
annex enables the transmitting encoder to use
four motion vectors fo r e ve ry m ac ro block (one
motion vector per block). A macro block is a
piece of the picture that contains four blocks.
Without this annex, the transmitting encoder
can only choose one motion vector for optimal
prediction of the macro block.
•Annex N - Reference Picture Selection Mode.
This annex enables the conference to recover
efficiently after transmission errors have
occurred in the macro bloc ks , an d repo rted via
a relevant message to the speaker encoder.
•Annex P - Reference Picture Re-sampling.
This annex enable s the tran smitting encoder to
apply a re-sampling process to the previous
decoded reference picture in ord er to genera te
a warped picture, for use in predicting the
current picture. The main purp ose of this annex
is to support the relationship of the current
picture to a previous picture, wh ich had a
different source format, such as CIF, QCIF,
4CIF, etc.
Chair ControlChair Control is an option that enables an endpoint
to control the conference and other conference
participants. This option is used to enable the
Chair Control. This option is enabled when the
Cascade field is set to None.
CascadeCascade is an option that enables you to run a
conference that is connected directly to other
conferences (these conferences are not
connected directly to ea ch other). The co nferences
may run on different MCU’s or on the same MCU
(for large conferences that exceed the maximum
number of participants per conference). This
option is used to enable and select the cascading
mode.
Master NameWhen setting a Slave conference, the Cascading
option should b e se t to Slave, and the nam e of the
participant that acts as the link to the Master
conference is select ed from the Master drop-down
list.
Roll CallRoll Call is a feature of the IVR Message Service
used to record the participants name and play it
back when entering and leaving a conf eren ce .
The chairperson can request the system to play
the names of all connected conference
participants at the beginning of the conference, or
at any time during the conference.
This option may be enabled only when the Roll
Call option is enabled in the IVR Service assigned
to the conference. When enabled for the
conference, the participant records his/her name
upon connection to the conference and the
chairperson may request a roll call in which the
recorded names of all conference participants are
played back to the conference.
If Entry Tone and Exit Tone are enabled for the
conference, participant name is played when the
participant enters or leaves the conference.
If Roll Call option is disabled for the conference bu t
enabled in the assigned IVR Service, the
participant name is recorded as the Roll Call may
be enabled during the on going conference , but roll
call cannot be requested.

Same Layout is a feature that “sets” and imposes
an identical video layout for all participants. During
the reservation stage, the moderator is able to
select a specific layout of his choice and apply the
selected layout settings to all conference
participants. It allows conference participants to
view his/her own video image.
When Same Layout is enabled during the
reservation stage, conference participants can
view his/her own vi deo im age to en sure th at ima ge
projection is of a reasonable quality (for example:
distance, focus, ligh tning, pos ture, and
presentation).
Auto LayoutIn Auto Layout the system automatically selects
the conference layout based on the number of
participants participating in the conference. With
Auto Layout, when a new video participant is

AGCThe Auto Gain Control (AGC) is the system
default.
Clear this check box to disable the Auto Gain
Control (AGC) for the participant.
The Auto Gain Control mechanism regulates
noise and audio volume by keeping the received
signal to all participants balanced. Different
endpoints and phones produce different types of
source noise and volume. The Auto Gain Control
mechanism can be applied to all incoming audio
streams prior to mixing, thereby dynamically
changing the amplification of the input signal
providing a constant output amplitude.
EncryptionIn the Participants Defaults -Settings2 you can
select the appropriate Encryption default setting - Auto/On/Off.
Choose any of the following Encryption options:
•Auto - When participants connect to a
conference, the conference/Entry Queue
encryption settings are automatically applied

conference/Entry Queue is set to encryption
the participant is also encrypted (if the flag in
the MGC Manager
ALLOW_ENCRYPT_IN_PARTY_LEVEL is set
to YES).
•On - enables encryption at the participant
level (if the flag MGC Manager
ALLOW_ENCRYPT_IN_PARTY_LEVEL is set
to YES).
•Off - disables encryption
Note: Undefined participants are connected with
the Participant Encryption option set to Auto,
inheriting the Conferenc e/En try Qu eue encryption
setting.
Restrict OnlyThis field appl ies only to ISDN c onnections. Select

sip: [user name]@[domain].
Note that the SIP URI adheres to URI rules: no
spaces or special characters such as commas,
quotation marks, inverted tags and so forth either
in the user name or in the domain part.
[To compare to H.323, which uses the endpoint location
for identifying the participant, in SIP participants can
change locations but still be addressed as long as they
continuously refresh their registrations with the proxy.
The proxy forwards invitees to their current location.
SIP URI: A SIP URI uses the format of an email
address, typically containing a username and a
host name, sip:user@host. For example,
sip:dan@polycom.com.
TEL URL: "Tel" means that a voice call is op ene d.
TEL URL may be used when the UA does not
wish to specify the domain that should interpret a
telephone number that has bee n input by the user .
Rather, each domain through which the request
passes would be given that opportunity. As an
example, a user in an airp ort might log in and send
requests through an outbo und proxy in the airport.
If they enter "411" (this is the phone number for
local directory assistance in the United States),
that needs to be in terp reted and processed b y the
outbound proxy in the ai rport , not the user's home
domain. In this case, tel:411 would be the right
choice.

Managing the Default Sets
The MGC Web Server Manager application is installed with an embedded
Defaults set. If no Defaults set is defin e d as the Global Defaults set, the
embedded Defaults set is active.
A Defaults set may be set as Private o r Global Defaults. A Global Defaults
set is a default set that will apply to all the database users. A Private
Defaults set applies only to users wh om it is specifically allocated a s the
Private Defaults set, and is used instead of the Global Defaults set.
The administrator can select one of the default sets defined in the database
as the Global Defaults set. However , the datab ase users can also define on e
of their default sets as Private Defaults set. In such a case, the user will be
able to use this set instead of the Global Default set.
Only one Defaults set may be defined as Private Defaults set. Selecting
another Defaults set as Private Defaults Set automatically cancels the
current Private Set. One set may be defined as both Global and Private
Defaults set.
The selection of the Global and Private Default set is done separately for
each Defaults category.
If more than one database is i nstal le d, the syst em loads t he P rivate d efaul ts
from the database designated as Private and the Global Defaults from the
database designated as Global. Therefore you must define the database
from which you want to load the Private Defaults set as Private and the
database from which you want to load the Glob al defaul t set as Gl obal. You
may define the same database as both Global and Private. In that case, the
Global Defaults set and the Private Defaults set will be taken from the same
database.
You can also designate a database as Private Default and another database
as Global Default. When a user loads the Global o r the Pr ivate defau lts, it i s
loaded from either the Private or Global Default database according to the
selected Default set. For example, if you select to load the Private Default
set, it will be loaded from th e database designated as the Private Defaults
database.
Using the right-click pop-up menu you can also delete a default set or
change the default set parameters.

Auto Cascade
The Auto Cascade feature enables automatic cascading of conferences. Both
audio only and video conferences can be cascaded.
The automatic cascading of conferences is beneficial in distributed MCU
environment, when MCUs are installed in different locations. A maximum of
six conferences can be Auto Cascaded into one conference. The MCU
network can support multiple Auto Cascaded conferences simultaneously.
Auto Cascading Mechanisms
The Ad Hoc Cascade is part of the Central Server Service that is installed as
part of the MGC Web Server Professional installation. The Central Server
Service monitors all the MCUs that are defined and connected in the MGC
Web Server Manager. When two or more MCUs are running a conference
with the same Conference Numeric ID, the Central Server Service checks if
the conferences are already cascaded. If there are no connected cascading
links, it will automatically connect the conferences using pre-defined
cascading links. If at a later stage an additional MCU running a conference
with the same Numeric ID is identified, it will add this conference to the
cascaded conferences.
The links between the MCUs and other configuration parameters are defined
using the MGC Web Server Manager. A primary link is defined between each
pair of MCUs to be included in the Auto Cascade. A secondary link can
optionally be defined for use as a backup if the primary link fails.
4-2
Selection of the Master Conference
The conferences are cascaded in a star configuration - one master and up to
five slaves. The master conference is selected when cascading first takes
place between two or more conferences.
If chairperson activation is enabled in the Auto Cascade configuration in the
MGC Web Server Manager, then the master conference is determined as
follows:
•If one of the conferences has a participant who is defined as a
chairperson, and none of the other conferences has a chairperson, the
conference with the chairperson will be assigned as the master
conference.
•If none of the conferences has a chairperson, then the conference that is
running on the MCU which is highest in the MCUs table in the Web
Server Manager will be assigned as the master conference.
•If there is more than one conference with a chairperson, then the
conference with a chairperson that is running on the MCU which is
highest in the MCUs table in the Web Server Manager will be assigned
as the master conference.
If chairperson activation is disabled, then the conference that is running on
the MCU which is highest in t he MCUs tabl e in the Web Server Manager will
be assigned as the master conference.
Chairperson Activation
If chairperson activation is enabled in the Auto Cascade configuration in the
MGC Web Server Manager, then the cascaded conference can implement the
“Start when the chairperson connects”, and “Terminate conference after the
chairperson exits” features, provided these options are selected in the
individual conferences.
Starting the Conference to be Cascaded
If the “Start only when the chairperson connects” option is implemented,
participants in all conferences will be placed on hold until a chairperson joins
one of the conferences.
Terminating a Cascading Conference
If the “Terminate conference after the chairperson exits” option is
implemented, all conferences will be terminated when there is no longer a
chairperson connected to a conference. In addition, the system will terminate
a slave conference when it no longer has any live participants, and will
terminate the master conference when no participants are connected and no
slave conferences with connected participants are still connected to it.
Implementation of Chairperson DTMF features
The following chairperson DTMF actions are implemented across the MCUs:
•Mute all but me
•Terminate the conference
•Place the conference on hold
•Lock and unlock the conference
•Secure the conference and release a secured conference

NO on all MCUs.
•H.239/People + Content is not supported with Auto Cascading.
•The Auto Cascade feature can only be implemented for the database
assigned as the Global Default in the Web Server Manager. To assign a
database as the Global Default, right-click on the database and select the
Set as Global defa ult option.
•The MGC Manager and WebCommander monitoring is per MCU,
therefore cascaded conferences are monitored as separate conferences
and not as one large conference
•Operator assistance is per MCU.
•The following chairperson actions are not implemented across MCUs:
Voting, Question and Answers, Replay Roll Call, Change password.
•All the MCUs must have IVR/DTMF licenses.
•In Continuous Presence conferences, the layout must be set to full
screen.
•For H.263 4CIF and H.264 Continuous Presence conferences, the link
will be defined as H.263 CIF.

•In the MGC Manager application, for each MCU define an Ad Hoc Auto
Cascade Entry Queue. The cascaded link is established when one MCU
dials the connection string of the Entry Queue defined on the second
MCU followed by the Conference Numeric ID. Calls to Auto Cascade
Entry Queues will be considered as MCU calls and no IVR will be
played.
For more information refer to the MGC Manager User’s Guide Volume
II, Ad Hoc Cascading.
It is recommended to set up identical Ad Hoc Ent ry Queu es and Pro files on each
MCU, so that the cascaded conferences will have the same properties.
Configuring the Cascading Links using the Web Server Manager
The Web Server Manager is used to set up the properties of the primary and
optionally, the secondary links between MCU’s.
Before con figuring the Cascading Links, you must define all the MCUs that will
be included in the Auto Cascading environment.
To Configure the MCU Cascade Links:
1.In the main W eb Server Manag er window , sel ect the database assigned as
the Global Default.

MCU Redundancy
The Central Server Service is designed to monitor th e activity of assigned
pairs of MCUs, so if one MCU in th e pai r enc ount er s a p robl em t hat prevents
it from running conferences, the other MCU will take over smoothly.
In Central Server Service environment, as described in Figure 4-1, MCU A
and MCU B are both registered in the gatekeeper with the same prefix and
they are designated as backup to each other in the WebCommander Central
Server Service.
The Central Server Service monitors both MCUs. When a new on going
conference is created on one MCU (for examp le, MCU A), th e Central S erver
Service automatically copies this conference to the second MCU (for
example, MCU B) with the prefix *bck_. In the same way, when new
reservations and Meeting Rooms are created on one MCU they are
automatically copied to the second MCU.

When one MCU is down (for example, power shortage), the gatekeeper will
identify that one MCU (A) is unavailable and will automatically forward the
calls to the second MCU (B). The participants are connected to the
conference that was copied from MCU A with the same name.
When the first MCU (A) is up and running again, the gatekeeper will connect
the participants to conferences running on MCU A. If a conference with the
same ID is now running on both MCUs (for example, if MCU A recovered
quickly, participants that connected later were connected to MCU A), the
system will automatically cascade both conferences (using the Auto Cascade
feature) to create one conference. This will eliminate the need to disconnect
and reconnect participants to a single conference.
If the origin conference i s ter minated o n one MCU its ba ckup conferen ce will
be automatically terminated on the second MCU.
In the same way, if ISDN PBX is configured to route calls from one MCU to
another according to MCU availability, the same behavior will occur.
The Central Server Service is disabled in Secure Mode.
Redundancy Guidelines
•ISDN and IP Network Services must have the same configuration (for
example, MCU Prefix in gatekeeper , dial -in numbers range, etc.) on both
MCUs.
•Conference Profiles, Entry Queue and IVR Services must be iden tical on
both MCUs.
•Entry Queues must be identical on both MCUs.
•The following conference parameters are copied from the source MCU
to the target MCU (backup):
— Conference duration
— Passwords (chairperson and conference entry)
— User Defined fields
— Billing Code
— Lecture Mode parameters
— Layout and Auto Layout
