2. General
What is MCS 5100?
MCS 5100 is one of Nortel’s unified communications solutions for Enterprise Multimedia and
Collaborative Applications. MCS is integral to Nortel’s vision of a comprehensive 'always on
integrated communications' solution embracing asynchronous and synchronous modes and
interfacing to business applications, all based on SIP. MCS 5100 utilizes Commercial Off The
Shelf (COTS) hardware to evolve PBX and IP PBX networks to multimedia and collaborative
communication networks. While MCS 5100 does provide PBX capability, it is better positioned as
an application server that has the ability to transform the way an enterprise communicates, enabling
users to take advantage of next generation tools that improve productivity, reduce operations costs,
and facilitate fast decision making. New efficiencies in business processes enable users to conduct
business more effectively and increases user mobility by removing barriers of distance and location.
MCS 5100 brings together advanced communication and collaboration capabilities within a single
converged communications solution , including features such as: multimedia (video and voice
calling); Meet Me Conferencing (audio and video), collaboration (Ad Hoc Conferencing, instant
messaging and chat, web collaboration, white boarding, file exchange, co-Web browsing);
personalization (call screening and routing and call management); and presence.
How is MCS 5100 positioned as part of Nortel’s Enterprise portfolio?
Nortel Multimedia Communication Server (MCS) 5100 is a strategic component of Nortel’s
Enterprise Multimedia portfolio. It delivers multimedia and collaborative applications to enhance
the enterprise users’ communications experience increasing productivity and mobility while
driving more powerful customer interaction and reducing communications costs. It is intended as a
complimentary solution to existing PBX systems as opposed to being a PBX replacement solution.
Does MCS 5100 deliver Unified Communications?
MCS 5100 is a very good example of a solution that delivers unified communications to the
enterprise as it unifies all of an end user’s communications (IP telephony, group collaboration,
instant messaging, presence, email) from a single client interface. An end user can launch virtually
any communication from within the MCS 5100 soft client which can operate as a standalone
application or in turn be embedded within IBM Lotus Notes or Microsoft Outlook.
How is MCS 5100 positioned against what Nortel is doing with Microsoft through its
Innovative Communications Alliance (ICA)?
Nortel offers customers choice in unified communications solutions. Customers will want to
choose the solution that bests satisfies their needs depending on their desktop environment.
How does the MCS 5100 benefit the Enterprise?
Nortel MCS 5100 provides significant benefits to enterprises and specifically addresses the
applications of mobility and convergence of voice, video, and data, evolving current telephony
infrastructure to a multimedia engaged network with a converged multimedia desktop solution.
Key values for the enterprise that support business users who are highly mobile and have

Why is MCS 5100 important to enterprise communication?
Nortel MCS 5100 simplifies communications with enhanced reachability that enables users to
maintain business communications no matter where they are. MCS 5100 enhances an
enterprise’s communication network, allowing users to specify how they wish to communicate
with the world by providing a central address (phone number and/or e-mail/alphanumeric address)
for all forms of communications (video, voice, text, and data). With MCS 5100, the network is now
intelligent enough to handle communications according to a user’s preferences, as well as
coordinate all of the various forms of communication.
What are the key features offered by the MCS 5100?
The MCS 5100 supports a variety of features that improve communications for users. It offers new
streamlined ways to reduce redundancy and clutter in everyday activity – email and voice mail

expanding user mobility, and enhancing interactive communications. It is Nortel heritage of
technology design, development, reliability, scalability, interoperability, and breath of
application/feature support incorporated within MCS 5100 that positions the offering in this rapidly
emerging collaboration and multimedia market segment.
What is the availability of the MCS 5100?
MCS 5100 has been generally available since July 2003. MCS 5100 Release 4.0 is the current
generally available release as of March 5, 2007. Over the years, MCS 5100 has received numerous
industry awards including enabling Nortel to remain in Gartner Magic Quadrant leadership
position.
What is the estimated price per user for the MCS 5100?
A typical MCS 5100 configuration supporting 100 users has a manufacturer suggested retail
price (MSRP) of approximately $103 per user excluding hardware. A 500 user configuration is
approximately $69 excluding hardware. Specific pricing is dependent on the customer application
and system configuration.
Hardware
What hardware does the MCS 5100 operate on?
Nortel MCS 5100 core system currently operates on IBM x306M servers. MCS 5100 applications
as part of the Media Application Server (MAS) operate on IBM x335/x336/3550, and Blade
Center-T.
Is there a small enterprise system?
Yes, the small enterprise system is based on a single IBM x306M server. It is not available in a
redundant configuration. The small system supports a maximum of 400 users. The small system is
upgradeable to a medium system.
Can the small enterprise system be upgraded to a medium system and if so, is my investment
preserved?
Yes, the small enterprise system can be upgraded to a medium system. Hardware components and

6. licensing are preserved. Note, that the MCS must be taken out of service and reconfigured during
the upgrade process.
What type of redundancy does the MCS 5100 support?
The MCS 5100 supports hot failovers where a backup server can assume control of a failed primary
server without disruption to end users.
Is geographic redundancy supported?
Yes, this is available for layer 2 and layer 3. Replication of the entire core system is necessary.
With layer 2 redundancy, Session Managers must be on the same subnet but can be geographically
dispersed. Calls stay up when failover occurs. With layer 3 redundancy, active and backup servers
can be on separate subnets. When a failure of the primary system occurs, calls fail as users must
re-register to backup servers. Layer 3 redundancy requires the Nortel Application Switch 2424 in
the solution to re-direct SIP users.

• Music On Hold
• Recorded Announcement
What video conferencing capabilities are supported?
Desktop point-to-point video, desktop Ad hoc and Meet Me video conferencing and desktop to
boardroom based systems (e.g. Tandberg) are supported. MCS supports point to point video as
part of the systems base software. Ad hoc and Meet Me video conferencing requires the MAS
server and Ad hoc or Meet Me audio and video software. To integrate with boardroom systems,
MCS inter works with the 3rd party Multipoint Control Units (MCUs) such as available from
Tandberg, which enables multi-point video conferencing between SIP-based video conferencing
devices, H.323, and H.320/ISDN legacy video equipment.
Is video conferencing available for both Ad Hoc and Meet Me Conferencing?
Yes.
What happens to my existing investment in video conferencing equipment?
Interworking with 3rd party MCUs that support SIP devices is supported. As such, using these 3rd
party MCUs, interworking can be achieved between SIP-based video conferencing devices, H.323,
and H.320/ISDN legacy video equipment. Refer to Nortel’s Developer Program for a list of
supported 3rd parties.
What is web collaboration?
Web collaboration enables groups of users to share documents or applications through use of the
web. There are 2 modes, one for document publishing which is well suited for presentations. The
other mode is document sharing which enables users to pass control of a document or application
amongst one another. The person with control has complete control of the document or
applications and it enables that user to make changes to a document and share the changes
real-time.

8. Does the web collaboration application support document sharing?
Yes, document sharing of virtually any document type or application is possible since sharing is
enabled by providing remote control of the document or application.
What is IM Chat?
IM Chat enables users to setup public or private chatrooms that can be used by MCS client users. 3
types of chatrooms are supported:
1. Private – not visible to MCS users that view the list of available chatrooms and users can
only join by invitation.
2. Public with password – visible to all MCS users but users can only join if they know the
correct password.
3. Public – visible and available to all MCS users.
How does the IM Chat application differ from the IM Chat function available with Meet Me
Conferencing?
The IM Chat function available with Meet Me Conferencing is almost the same as the one available
with the IM Chat application. The primary difference is that with Meet Me Conferencing, only
private chatrooms are available. The chairperson of a Meet Me conference launches the private
chatroom by pressing *2. All MCS participants receive a chatroom invitation. Additionally, the
IM Chat function available with Meet Me Conferencing is built in to the Meet Me Conferencing
application and does not require an IM Chat server or IM Chat licenses. Once the private chatroom
is launched, additional parties can be invited to join the chatroom.
Other features
How can I use my existing corporate database information to provision the MCS 5100?
The MCS 5100 database can be populated using an LDAP database. Any changes made to the
LDAP database can be synchronized to the MCS 5100 database. Note that users that are deleted
from the LDAP database do not get deleted from the MCS 5100 database but instead are placed
inactive. MCS 5100 administrators can then view the lists of inactive users and delete them as
appropriate.
Does MCS 5100 support E911?
Yes, E911 zoning is supported. During the login process to MCS, users select their location from
an administrator defined list of locations. This ensures that when a user dials 911, the call is
directed to the local Public Safety Access Point (PSAP). MCS can also provide additional
information such as specific location via file transfer to the PSAP (providing this is supported by
the PSAP). Additionally, MCS supports on-site notification such that an Instant Message can be
delivered to a designated location (e.g. security desk).
What E911 support is there for users working in remote locations?
There is support providing the user is in an administrator defined list of locations. If the user is not,
then they should specify that they are in an undefined location and they will receive a warning that
they should not use their MCS client to dial 911 if unable to communicate their location.

9. Does MCS 5100 support an Assistant Console?
Yes.
What is the Converged Desktop?
The Converged Desktop greatly increases the integration between the MCS 5100 and CS 1000
platforms. It enables:
• Dynamic presence over the CS 1000 attached phones.
• Supports analog, digital, and IP phones.
• Converged desktop users utilize their desk phone for voice and their PC client for
multimedia (e.g. IM, chat, click to call, video, web collaboration, call logging).
Is IM recording supported?
Users have the ability to save their IM conversations locally on their PCs for the recording of IM
messages. Automated recording of IM’s at the system level are not available natively at this time.
This type of function is available through 3rd parties. Refer to the Nortel Developer Program for
details.
Can the MCS IM function communicate with public IM systems such as Yahoo?
Not at this time. This is under consideration for a future release.
Does MCS 5100 support public/private name and number display?
Yes, system administrators can provision public names for users such that PSTN calls display
public names if provisioned instead of the private name that would be displayed for internal calls.
This is provisionable on a user, sub-domain or domain basis.
Does MCS 5100 support any customization?
Yes, there are a few options.
• There is a theme developer kit which enables customers to customize the Multimedia PC
Client?
• The Multimedia PC Client supports an Application Programming Interface (API) such that
3rd party PC based applications can invoke multimedia communications through the client.
• Similarly, a “headless” version of the client is available through the Nortel Developer
Program which enables applications to invoke multimedia functions of the client without
the end user having to launch the client or even see the main client screen
• There is a subscriber Open Provisioning Interface to 3rd party applications for subscriber
management which is available through the Developer Partner Program. This enables
access to all options in Personal Agent and enables the gathering and modification of such
information. As an example, a location application could update presence and reachability
routes.
• Granular service packaging is available to the system administrator to enable certain
functions of the Multimedia PC Client to be disabled and hidden from the end user.

10. MCS 5100 Audio Conferencing Solutions
What’s the difference between Meet Me Conferencing and Ad Hoc Conferencing?
Ad Hoc conferencing is used for adding additional persons to a conversation. This feature is also
referred to as 3-way or 5-way conferencing. For example, if two persons are engaged in a voice
conversation, the participants can dial a third person, and have another participant join the
conversation. Other participants can be added up to the limit configured by the system
administrator for that user. Note that it does not matter who called who. It is even possible for a
person engaged in 2 conferences to join those 2 conferences together.
Meet Me conferencing provides an audio bridge function. Each user is given their own personal
access code and chairperson password. To hold a conference, the chairperson provides their unique
access code to all expected participants such that all participants dial into the conference bridge and
provide the given access code. Note that bridge numbers and access codes are permanently
assigned to individual users.
Can I schedule conferences for the Meet Me Conferencing application?
Yes, each user is given their own personal access code and chairperson password and as such
conferences can be scheduled such that bridge information can be sent out well ahead of the
meeting, however, note that today, Meet Me conferencing is reservation-less, that is, audio ports
are never reserved on the server and are subject to a first come, first served basis. Reservation
based conferencing is planned for a future release.
Can I reserve conferences for the Meet Me Conferencing application?
No, today Meet Me conferencing is reservation-less, that is, audio ports are never reserved on the
server and are subject to a first come, first served basis. Reservation based conferencing is planned
for a future release.
What advantages does reservation-less conferencing offer?
Reservation-less conferencing provides for maximal use of system resources. Unused ports are
always available to other users. This enables an enterprise to oversubscribe the Meet Me
Conferencing application thereby lowering total conferencing expenditures.
Is recording of Meet Me conferences available?
Yes, the chairperson has the ability to start and stop conference recording.
How does Meet Me conference recording work?
The chairperson has the ability to start and stop conference recording using the DTMF command
*9. When the chairperson stops conference recording or when the conference is terminated, the
conferencing server saves the recording into a .wav file and emails it to the chairperson. When
conference recording is enabled/disabled, participants are warned that recording is on/off. Even if
participants join a conference after recording has started, they will be automatically informed that
conference recording is active.
Are quick start conferences supported for Meet Me Conferencing?

11. Yes, the chairperson has the ability to configure their bridge for quick start. With quick start, the
conference starts as soon as the first person joins the conference as opposed to having to wait for the
chairperson to join the conferencing.
Can other participants assume the role of chairperson?
Yes, but only if the chairperson leaves the bridge. A participant may then press *0 and enter the
chairperson’s pin to assume the role.
What chairperson controls are available with Meet Me Conferencing?
Following is a list of control functions available through the Telephone User Interface (TUI):
*0 Assume chairperson role †
*2 Launch private chat room for conf. attendees
*4 Lock , *5 UnLock conference
*6 Mute, *7 UnMute †
*8 Toggle conference continuation upon exit
*9 Toggle conference recording
*# Query number of participants †
## mute all, 99 unMute all
2(n) where n = audio emotion (clap, etc.) †
00 Call for operator †
** Help †
91 start web collaboration session, 92 stop web collaboration session
† Available to all participants
What operator controls are available with Meet Me Conferencing?
Operators have access to all the chairperson controls through the TUI as well as the MCS
Provisioning Agent. Additionally, through the MCS Provisioning Agent, operators can also
terminate and mute/un-mute specific lines.
MCS 5100 Video Solutions
What video solutions are offered on the MCS 5100?
The MCS 5100 offers many alternative solutions for video.
1. Point-to-point desktop video: This solution enables PC and Web client users to
communicate using video in point-to-point conversations.
2. Point-to-point video with compatible 3rd party endpoints: This solution enables PC client
users to communicate with compatible 3rd party endpoints in point-to-point conversations.
3. Desktop multi-point video or MAS-based video conferencing: This solution which is
available on the Ad Hoc and Meet Me conferencing servers enables PC and Web client
users to engage in a multi-point video conference. This solution supports switched video.
3rd party clients can not participate in the video conference.
4. Advanced multi-point video: This solution makes use of compatible 3rd party bridges or
Multipoint Control Units (MCUs) to provide the multi-point conferencing bridge functions.
These will generally provide support for legacy H.320 video equipment as well as H.323
video equipment and may support continuous presence.

12. Note: Refer to the Nortel Developer Program for a list of compatible 3rd parties
http://www.nortel.com/prd/dpp/product/index.html.
What do I need to be able to do video at my desktop?
If using an MCS 5100 soft client, the only hardware requirement for desktop video is a web cam.
Alternatively, the IP Phone 1535 (SIP video phone) or compatible 3rd party video endpoints can be
used.
What is the difference between switched video and continuous presence?
Switched video which is supported on the MAS-based video conferencing enables users on the
video conference to see the most active speaker. In other words, users only see one video source at
a time and when another participant begins to speak, the video will switch to that participant.
Continuous presence which is available with some 3rd party conference bridges enables users to
simultaneously see multiple video sources. This is sometimes referred to as the “Hollywood
Squares” view or “Brady Bunch” view. The following picture is an example of continuous
presence.
Can audio only users participate in a video conference?
Yes, users can participate in the audio portion of a video conference if they are only equipped for
audio.
Do I need a web cam to be able to receive video?
No, users can still see other participants’ video feeds even if they aren’t equipped with a web cam,
however, they will not be able to transmit video.
What web cams are supported on the MCS 5100?
The MCS 5100 will operate with most web cams in the market.
When will the MCS 5100 support reservation-based video conferencing?
Reservation-based video conferencing is planned for a future release on the MAS-based video
conferencing bridge. Reservation-based video conferencing is likely available from the compatible
3rd party MCUs supported.
Which video codecs are supported on the Meet Me and AdHoc Conferencing applications?
Only the DIVX video codec is supported on the conferencing applications at this time.

13. When will the MCS 5100 MAS-based solution support the H.263 or H.264 video codecs?
H.263 and H.264 video codec support on the MAS are under consideration for a future release?
When will the MCS 5100 MAS-based solution support continuous presence?
Continuous presence support is under consideration for a future release?
How are video solutions licensed on the MCS 5100?
Desktop video is included with the base MCS software. In order to use video with Ad Hoc or Meet
Me conferencing, video port licenses are required on the respective audio servers. One video port
license is required for each active video client. The video port licenses are incremental to the audio
conferencing port licenses.
What collateral or documentation is available for this solution?
• There is a Nortel written white paper titled “The Role of Video in a SIP-Enabled
Collaborative World” available on Global Web and nortel.com (www.nortel.com).
If a customer has existing 3rd party video equipment, will it work in this solution?
Providing the equipment can be upgraded to the required software level then it should work. Older
equipment can also be supported through the 3rd parties as they may support legacy equipment. In
any case, customers should contact the 3rd parties directly for assistance and refer to the Nortel
Developer Program website for additional information.

14. MCS 5100 Web Collaboration
What do participants require to join in web collaboration?
The only requirements on participants who wish to join a web collaboration session are for a
compatible web browser such at Internet Explorer or Netscape with Active X enabled.
How do users join a web collaboration session?
Users can join a web collaboration session in one of 2 ways. First, by joining the Meet Me Audio
Conference from an MCS client, users will automatically receive a web push which will connect
them to the web collaboration server. Second, the chairperson may publish a URL which will
connect users to the web collaboration server.
Can a user join the web collaboration without an MCS 5100 client?
Yes, an MCS 5100 client is not required to participate in a web collaboration session. The
chairperson may publish a URL or provide the URL in an email to participants. The URL for
participants can be found under the Meet Me preferences found in the Personal Agent.
How can users not connected to their corporate network access web collaboration?
In order for users that are outside the company to access a web collaboration session, they would
need access to the web collaboration server. This can be accomplished by locating the web
collaboration server outside the firewall, by opening the necessary holes in the firewall, or by
traversing the firewall using an IPSec or SSL VPN.
Do users need to reserve a web conference?
No, web collaboration is reservation-less.
Can other participants be presenters or application sharers?
Yes, the chairperson can pass control to another participant in document publishing mode such that
the other participant controls the document being published. Similarly, the chairperson can pass
control to another participant in application sharing mode such that the other participant can share
applications on their desktop or make changes to the application being shared. Note that the
application continues to reside on the desktop of the participant sharing the application and the
changes are made on that person’s desktop.
Can multiple participants make changes at the same time when sharing an application?
No, only one person at a time can make changes to an application.
What is the difference between document publishing and application sharing?
Document publishing is for presentation purposes only. Users can not make changes to the content.
Application sharing enables the chairperson to make changes to the shared application and all
participants see the changes dynamically as they occur.
Why is there a need for both publishing mode and an application sharing mode?

15. The publishing mode provides better performance than the sharing mode and optimizes bandwidth
by converting documents before publishing the document.
Can PowerPoint builds be used?
Yes for application sharing. No for the publishing mode because the PowerPoint file is converted
to JPEG image for broadcast to the other web collaborators. Note that Word and Excel files are
rendered into HTML images when published.
What security exposures are introduced by allowing someone to share a desktop?
Showing someone your desktop does not pose a security threat, however, giving them control of
your desktop potentially does. With control of your desktop, a user can pretty much do anything to
it as if they were sitting at your desktop including deleting files.
Do participants in an application sharing session need to have the application being shared
installed on their PCs?
No, only the chairperson needs to have the application being shared. Note that when accessing web
collaboration for the first time, participants may be asked to download and install software in order
to join a web collaboration session. If so, the web collaboration application will prompt the user
through the process.
Can multiple web collaboration servers be used to share the same information?
A single web collaboration session can not span multiple web collaboration servers.
Is it necessary to have Meet Me conferencing to do web collaboration?
Yes, the web collaboration server works in conjunction with the Meet Me conferencing server. The
chairperson launches the web collaboration by issuing DTMF (pressing 91 on the telephone)
commands once connected to the Meet Me conference.
Can a web collaboration server support multiple Meet Me conferencing servers?
Yes.
How many web collaboration sessions are supported from a single server?
1000 document publishing or application sharing sessions or a combination of both.
Does the web collaboration application support polling?
Yes, the chairperson can submit multiple choice questions to all participants. The polling function
provides cumulative results. As participants complete the poll, the results are updated real-time.
The chairperson does not see individual responses. The chairperson has the option to publish the
results to all participants.
Does the web collaboration application support file transfers?
Yes, through the web collaboration application, the chairperson can perform point-to-point and
multi-point file transfer to all participants.

16. Does the user need to purchase Microsoft Office for the server?
Yes, Microsoft Office for the web collaboration server must be purchased by the customer from a
MS Office reseller.
Can customers’ bill usage back to internal departments?
Yes, session information reports are available. Customers can obtain usage information for
department billing purposes from these reports.
