Environmental issues
Thank you for buying a product which contributes to a reduction
in pollution, and thereby helps save the environment. Our
products reduce the need for travel and transport and thereby
reduce pollution. Our products have either none or few
consumable parts (chemicals, toner, gas, paper). Our products
are low energy consuming products.
TANDBERG is pleased to announce that we have replaced the
printed versions of our User Guides with a digital CD version.
Instead of a range of different user manuals, there is now one
CD – which can be used with all TANDBERG products – in a
variety of languages. The environmental benefits of this are
significant. The CDs are recyclable and the savings on paper
are huge. A simple web-based search feature helps you directly
access the information you need. In addition, the TANDBERG
video systems now have an intuitive on-page help function,
which provides a range of useful features and tips. The contents
of the CD can still be printed locally, whenever needed.
As part of compliance with the European WEEE Directive,
TANDBERG provides recycling information on request for all
types of new equipment put on the market in Europe after
August 13th 2005.
Please contact TANDBERG and provide the following details
for the product for which you would like to receive recycling
information:
Model number of TANDBERG product
•
Your company’s name
•
Contact name
•
Address
•
Telephone number
•
E-mail
•
In order to avoid the dissemination of hazardous substances
in our environment and to diminish the pressure on natural
resources, we encourage you to use the appropriate take-back
systems in your area. Those systems will reuse or recycle most
of the materials of your end of life equipment in a sound way.
TANDBERG products put on the market after August
2005 are marked with a crossed-out wheelie bin
symbol that invites you to use those take-back
systems.
Please contact your local supplier, the regional waste
administration, or http://www.tandberg.com/recycling if you
need more information on the collection and recycling system in
your area.
As a manufacturer of electrical and electronic equipment
TANDBERG is responsible for compliance with the requirements
in the European Directives 2002/96/EC (WEEE) and 2002/95/
EC (RoHS).
The primary aim of the WEEE Directive and RoHS Directive is
to reduce the impact of disposal of electrical and electronic
equipment at end-of-life. The WEEE Directive aims to reduce
the amount of WEEE sent for disposal to landfill or incineration
by requiring producers to arrange for collection and recycling.
The RoHS Directive bans the use of certain heavy metals and
brominated flame retardants to reduce the environmental impact
of WEEE which is landfilled or incinerated.
TANDBERG has implemented necessary process changes to
comply with the European RoHS Directive (2002/95/EC) and the
European WEEE Directive (2002/96/EC).
Environmental stewardship is important to TANDBERG’s culture.
As a global company with strong corporate values, TANDBERG
is committed to following international environmental legislation
and designing technologies that help companies, individuals and
communities creatively address environmental challenges.
TANDBERG’s environmental objectives are to:
Develop products that reduce energy consumption, CO
• 2
emissions, and traffic congestion
Provide products and services that improve quality of life for
• our customers
Produce products that can be recycled or disposed of safely
• at the end of product life
Comply with all relevant environmental legislation.

The TANDBERG VCS
VCS and the TANDBERG Total Solution
The TANDBERG Video Communication Server
(VCS) enhances the video experience and
provides seamless communication between
SIP and H.323 devices utilizing IETF and
ITU standards. The VCS is the center of the
video communication network, and connects
all H.323 and SIP endpoints, infrastructure,
and management devices. The VCS provides
unrivaled scalability and redundancy to video
communications, and is integral to TANDBERG
interoperability with unified communications
and Voice over IP systems. The VCS can be
deployed with either the Control application
or the Expressway™ application, with various
optional packages including FindMe™, Dual
Network Interfaces and TMS Agent.

The TANDBERG VCS
VCS Control
The VCS Control provides internal video control and administration for all SIP and H.323 devices.
It is normally deployed within your wide area network with endpoints that are behind the same
firewalls or NAT devices.
The VCS Control replaces the need to have separate H.323 gatekeeper, SIP registrar and H.323 -
SIP gateway servers.
VCS base applications
VCS Expressway™
The VCS Expressway provides standards-based firewall traversal for SIP and H.323 devices allowing
secure firewall traversal of any firewall or NAT device. As well as all the functionality of a VCS
Control, it also provides registration of traversal-enabled devices and STUN Discovery and STUN
Relay services.
The VCS Expressway is normally deployed outside of your firewall or within the DMZ.

D14049.05
February 2009
Grey Headline (continued)
The following features are available on the VCS by the purchase and installation of the appropriate
option key:
User Policy (FindMe™)
A unique industry solution that gives individual video users a single alias on which they can be
contacted regardless of location. Users have the ability to log on to a Web-based interface and
control where and how they are contacted. The FindMe feature also includes support for Microsoft
Office Communications Server (OCS) 2007, enabling FindMe aliases to register as Microsoft Office
Communicator (MOC) clients, and MOC clients to view the presence status of FindMe aliases.
TMS Agent (Device Provisioning)
Installing the “Device Provisioning” option key on the VCS enables the TMS Agent feature. The TMS
Agent allows TANDBERG Movi™ v2.0 clients registered to the VCS to be provisioned with phonebook
and configuration information by connecting to the VCS rather than directly to TMS. All phonebook
and configuration data is managed in TMS, and distributed to the clients through the TMS Agent
running on the VCS. The TMS Agent on the VCS also provides TMS with the Movi client’s status.
There is no configuration associated with the TMS Agent on the VCS – it is either on or off,
depending on whether or not the option key is installed. See the TMS documentation and the
TANDBERG Provisioning Directory Deployment Guide [26].
Dual Network Interfaces
Enables the LAN 2 ethernet port on the VCS Expressway, allowing you to have a secondary IP
address for your VCS.
This option also includes support for deployments where a VCS Expressway is located behind a
static NAT device, allowing it to have separate public and private IP addresses.
This configuration is intended for high-security deployments where the VCS Expressway is located in
a DMZ between two separate firewalls on separate network segments.

The TANDBERG VCS

D14049.05
February 2009
Grey Headline (continued)
The following features have been introduced in version X4 of the
VCS software:
Multiway™
VCS now supports standards-based Multiway™. This feature
allows endpoint users to initiate ad hoc multiparty calls from
their endpoint, -even if the endpoint does not have embedded
MultiSite™ capabilities. To enable this feature you must enable
and configure the Conference Factory application on the VCS -
see the Conference Factory section for further information.
TMS Agent
The TMS Agent allows TANDBERG Movi™ v2.0 clients registered
to the VCS to be provisioned with phonebook and configuration
information by connecting to the VCS rather than directly to TMS.
See the TMS Agent section for more information.
Microsoft OCS 2007 interoperability
The VCS now includes an OCS Relay application, which makes
• FindMe presence information available to Microsoft Office
Communicator (MOC) clients, and enables Microsoft Office
Communications Server (OCS) 2007 to forward calls to FindMe
aliases. See the OCS Relay section for more information.
Neighbor and DNS zones now include a pre-configured zone
• profile for connections to an OCS. See the Zone profile
section for more information.
Static NAT support
A VCS Expressway with the Dual Network Interfaces option
installed can now be deployed in a DMZ with a static private
address mapped to a public IP address of the external firewall.
See the section About static NAT for information on using this
feature.
Password security
You can determine whether or not administrator passwords
• must meet a minimum level of complexity before they are
accepted. See the Administrator password security section for
more information.
The
• admin administrator account and the root account can
now have separate passwords.
A warning will appear if the password of the default
• admin
administrator account or the root account are still set to
the default. See the Administrator accounts section for
instructions on how to change these passwords.
Root account access
Access to the root account using Telnet and SSH can be disabled
to increase security on the VCS (access over Telnet is now
disabled by default). See the Accessing the root account over

Capacity warnings
The VCS can now raise a warning when it is approaching its
maximum licensed capacity for calls or registrations. This feature
is managed using the CLI only using the command:
ResourceUsage Warning Activation Level: <0..100>
Clustering
The replication of configuration information (including FindMe
information) no longer requires the use of TMS. Information is
replicated across the peers in a cluster within 60 seconds. See
the Clustering section for more information.
Call processing
The VCS has a new mode which will determine whether or not
• it will attempt to remove itself from the call signaling path.
See the Call routed mode section for more information.
The VCS can now be configured to detect and stop loops from
• happening during the search phase for both H.323 and SIP.
See the Call loop detection mode section for more information.
Administrator tools
The
• Check pattern tool allows you to test the outcome of a
pattern or transform before configuring it live on the VCS.
The
• Locate tool allows you to test whether the VCS can find an
endpoint identified by a given alias, within a specified number
of 'hops', without actually placing a call to that endpoint.
This tool can be used to diagnose dial plan and network
deployment issues.
The
• Port usage pages provide a convenient way to see a
complete list of all inbound, outbound and remote listening
ports used by the VCS. This information can be provided to
your Firewall Administrator to ensure the correct ports are
opened on the firewall.
Usability enhancements
In addition to the existing help for every input field, there
• is now help available for every page on the web interface.
This help gives an overview of the purpose of the page, and
introduces any concepts configured from the page including
when they may be used.
This help is accessed from the icon at the top right of
each page.
Registrations can now be viewed either as a list of all devices
• that have registered regardless of the alias(es) they have used,
or as a list of every alias registered on the VCS, regardless
of whether these belong to the same device. See the
Registrations by device and Registrations by alias sections for
further information.
Login banner
It is now possible to upload an image and text that will be
displayed when administrators or FindMe users log in the VCS.
See the Login page section for more information.

The Administrator Guide
This Administrator Guide is provided to help you make the best use of your TANDBERG VCS.
Your approach to this documentation depends on what you want to do and how much you already
know.
The Administrator Guide has been divided into several sections, each providing different
information. In some places information is duplicated between sections to let you have all the
relevant information in one place.
This document does not have an index. This is intentional; if the Table of contents does not direct
you to the information you need, you can use the Find function in Adobe Reader to search the text
for keywords.
Note that the Administrator Guide describes a fully equipped version. Your version may not have all
the described extensions installed.
Our main objective with this Administrator Guide is to address your goals and needs. Please let us
know how well we succeeded!
Using this Administrator Guide
Typographical conventions
Most configuration tasks on the VCS can be performed by using either the web interface or a
command line interface (CLI). This guide will describe how to use both methods.
Web interface
In this guide, instructions for performing a task using the web interface are shown in the format:
Menu > Submenu
•
followed by the Name of the page that you will be taken to.
Command line interface (CLI)
In this guide, instructions for performing a task using the command line interface (CLI) are shown in
the format:
xConfiguration <Element> <SubElement>
•
xCommand <Command
• >
These are meant as a reference only. Each command is hyperlinked to the Command reference
table at the back of this guide; clicking on the hyperlink will take you to the appropriate section
of the table showing all the available sub-elements, parameters and valuespaces for the given
command.
Note that:
Typing the given
• xConfiguration path into the CLI will return a list of values currently
configured for that element (and sub-elements where applicable).
Typing the given
• xConfiguration path into the CLI followed by a ?will return information about
the usage for that element and sub-elements.
Typing the given
• xCommand command into the CLI with or without a ?will return information
about the usage of that command.
