switching.
Emblaze-VCON Guide 1
1 Welcome to the VCB
The VCB includes the Conference Moderator, which provides administrators and
users with the ability to schedule conferences in advance, also from within MS -
Outlook, and to manage them remotely. At the appointed time, the Conference
Moderator initiates the conference and connects the conference participants.
Conference hosts can also control when participants join or exit sessions, and
transmit video and data streams to the participants. For more details, see the
Conference Moderator Help.
The VCB’s robust Chair Control provides several options for displaying conference
participants. A rich selection of predefined layouts expands on the traditional
methods of Continuous Presence and Voice-activated Switching. Additionally,
conference organizers can choose among the following view switching modes for
each session:
Lecture Showing the Lecturer in full screen mode for all
participants. Lecturer see a pre-defind Continuous
Presence layout of all participants.
Dominant
Speaker
Fixed Image Showing specific views throughout the conference’s
Timer Image Showing a rotation of Continuous Presence views,
The VCB supports the following:
T H.261/H.263/H.263+/H.263++/H.264 video transcoding support in Voice-
activated Switching and in Continuous Presence.
T G.711, G.722 and G.722.1 Annex C, G.723.1, G.728, G.729 and AAC-LD audio
algorithms with audio transcoding, allowing users to participate in a multipoint
conference using different audio standards.
T Up to 4 Mbps data rate per participant in Voice-activated Switching and in
Continuous Presence.
T Dial-in conference initiation.
T Password protected conferences.
T Voice notifications in different languages.
T Handles calls connecting up to 48 concurrent users.

2 Defining the VCB IP Configuration
2DEFINING THE VCB IP
ONFIGURATION
C
Before you can use the VCB for the first time, you have to define a unique IP
configuration for it. This task is made up of the following procedures:
T Retrieving the VCB’s initial IP configuration
T Changing the IP configuration to unique settings, such as a static IP
address
Connect to any one
of these interfaces.
For standard operation, we recommend that you connect one NIC/one
interface. If nevertheless, you require connection through more than one NIC,
each NIC must belong to a different subnet.
Connect a network cable to the interface you configured only after completing
the configuration.
Interface GbE0 has a fixed static
IP which cannot be changed.
2.1 Retrieving VCB initial IP configuration
The following procedure describes how to get the IP address from the VCB unit’s
front panel.
1 Connect a network cable to any one of interfaces GbE1 to GbE3.
2 Turn the VCB unit on. A welcome message appears in the LCD display.

VCB Backup/Restore
VCB supports a system backup and restore functionality to help recover immediately
the system in cases of disaster.
The Backup and Restore functionality saves the baseline (Factory Default) configuration, creates a new snapshot of VCB configuration once a week for 10 weeks and
allows you to manually create snapshots according to configuartion changes.
At any time, you can easily restore the default VCB configuartion (as was set at EVC)
or return to a specific configuration state.
Action
Choose the Action you want to perform:

ERMISSION GROUP
P
The tasks described in this chapter are procedures which you perform in
®
Emblaze-VCON’s Media Xchange Manager
application.
An Ad-hoc Permission group is a set of VCB services that are defined for use in adhoc conferences. It helps you control the use of resources for expanding to ad-hoc
conferences.
An Ad-hoc Permission group may consist of one service or multiple services. It may
also include combinations of services from more than one registered VCB unit. The
order in which services are requested is important and controllable by Super Userlevel administrators.
During expansion to an ad-hoc conference, the MXM only uses those services listed
in the inviting end point’s assigned permission group. After an invitiation is
initiated, the MXM first tries to use the first service defined in the permission group.
If the first service is not available, it tries to use the second defined service, and so
on. If all enabled services are unavailable, the MXM does not complete the
"invitation" to the additional end point.
By default, every registered end point is assigned to the default Ad-hoc Permission
Group. This may be changed when manually adding a new end point, or by editing
the end point’s properties.
