 Enhanced Video
 Conference Service
10.1         Overview
AT&T offers a suite of high quality, secure, and reliable videoconferencing services to
meet the diverse needs of the Government end-user community. These products and
services encompass both ends of the spectrum - products designed for those agencies who
are looking for AT&T to manage their videoconferences, and products designed for those
agencies who are looking to do it themselves. AT&T’s mix of products and services
gives customers the flexibility to build a platform that will satisfy their needs on any
level. Specifically, AT&T offers the following:

      Assisted Conferences (reservations-based) – through AT&T’s Video Bridging
       Service. This option is used primarily for ISDN-based video calls, but with the
       ability to add IP endpoints into a conference.

      On-Demand Conferences (reservation-less) – through AT&T’s Video Gateway
       Service. This option supports IP-based video calls, including desktop video.

AT&T has built reliable, state-of-the art video networks using ISDN circuit technology
(ITU-T H.320 standard) and IP technology (H.323 standard). These networks, coupled
with customized reservations, scheduling, and billing systems provide the tools to
respond quickly and effectively to meet the special needs of our valued customers.
AT&T’s secure and reliable videoconference services are based in Atlanta, GA, with
additional gateway facilities located in Chicago, IL.

10.1.1.1 Enhanced Video Conference Service Vendors
         and Configuration
AT&T Video Conference Service consists of both Avaya (formerly Lucent Technologies)
and Polycom (formerly Accord) Multipoint Control Units (MCUs). These MCUs provide
hundreds of public bridge ports to AT&T customers. AT&T can support up to |||||||| sites
on a single videoconference, since several MCUs may be cascaded to support large calls.

The MCUs are behind carrier-class switching devices maintained by our Engineering
Team. With |||||||| percent digital connectivity and decentralized topology, AT&T has
created network diversity and redundancy second to none. The AT&T video network
connects directly to AT&T, as well as other carriers, including MCI/WCOM, and Sprint.
All video MCUs can access all network providers on a call-by-call, site-by-site basis by
adding a prefix to the dialed number.

By using this switched environment, AT&T has built-in redundancy and flexibility in
case of network outages or loss of service. All equipment is located in a carrier-class
facility with zero-mile access to all major providers. These switches also provide the
ability to do ||||||||||||| traces and find technical problems in the Public Switched Telephone
Network and work with carriers to expedite resolution.

10.1.3.1.1            Conference Modes
Agencies may select from a variety of conference modes, or video-switching options, one
that is best suited for their needs - based on the nature of their meeting. Since meetings
are conducted in a variety of ways, AT&T offers different conference mode options to
accommodate the type of meeting required. For example, meetings may require

Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

interaction among multiple participants, or they may focus on a single speaker who
shares information with all other participants. There may also be a need to control who is
being viewed and heard at a given moment during the meeting. Whatever the meeting
need, AT&T has a solution to ensure a successful and effective conference experience.

The desired conference mode must be selected at time of reservation request; the default
option is voice activated switching. The following options are available for conferences:

Voice Activated Switching (VAS)

This mode is recommended for use in interactive meetings or when most of the
participants are expected to share information. With VAS, all conference participants
view the current speaker, and the speaker views the previous speaker. Unlike methods
employed by other service providers, AT&T uses advanced technology that allows for
more natural viewing by granting the current speaker the right to be the video broadcaster
until he or she stops speaking. AT&T’s service is based on a sophisticated speech
detection algorithm that can detect when the current speaker in the conference stops
talking and another speaker starts to talk. The result is that all participants see natural
video switching during the conference. VAS is always the default conference mode.
Note that when incoming audio is received from an “audio only” port, the video does not
switch.

Presentation

Presentation mode is ideal for classroom training and instructional meetings where there
is one primary speaker and limited interaction from the other participants. This mode is
commonly used for distance learning applications and single site briefings. Presentation
mode allows you to broadcast a single endpoint to all other endpoints in the conference.
The endpoint that is broadcasting is called the presenter. During the conference, all
endpoints continue to view the presenter, while the presenter sees the person asking a
question or making a comment. The site viewed by the presenter is chosen based on
VAS. For example, in a distance learning application, the students always see the
instructor and yet the instructor would see the student talking. In addition, all sites have

                                                                                                                      I-10-7
Contract # GS00T01AHD0002
Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

full audio capabilities so that they can hear the questions or comments from any other
sites, while they continue to view and hear the presenter. A specific endpoint must be
pre-assigned as the presenter when placing a conference reservation request. This
endpoint will remain fixed as the only broadcasting site that all other endpoints will view.
For more flexibility in assigning various sites as the presenter or broadcaster, please
consider using a Dedicated Conference Producer. The Dedicated Conference Producer
has full control of the bridge and can make any site the presenter “on the fly”. A
Dedicated Conference Producer is monitoring only one call at a time and is always
available for any such request.

Broadcast with AutoScan

This mode is recommended for one-way, non-interactive broadcasts. Ideal applications
include company announcements, test proctoring and non-interactive lectures. With this
option, all sites view a single broadcast site that is pre-assigned at the time of reservation
request. This mode allows you to broadcast, from a single endpoint, audio and video to
all other endpoints in the conference. In this type of conference, the only audio source to
the conference is that of the assigned broadcaster. The broadcasting endpoint does not
receive audio from any viewing locations, but does see video from each of the other
endpoints, one at a time. The site viewed by the broadcaster is chosen based on a timed,
rotating scan of all other sites in the conference. The automatic rotation allows the
broadcaster to use visual clues to gauge audience reaction. The timed interval between
successive video switches can be specified on a conference-by-conference basis. The
default time interval is 12 seconds. Please note this mode does not support Continuous
Presence; however, it is available on transcoded conferences.

Chair Control (H.243)

This mode, also known as Director Control when placing reservations with AT&T’s
service, is supported as long as the endpoint equipment is H.243-standard compatible.
This option is ideal for meetings where participants from several endpoints are each
scheduled to give an extended talk. This mode allows you to select and broadcast a

                                                                                                                       I-10-8
Contract # GS00T01AHD0002
Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

specific endpoint’s video to all other H.243-standard endpoints in the conference. An
endpoint with chair control can request video control, relinquish control of the
conference, select a site as the broadcaster, and drop a site or the entire conference. The
endpoint that assumes chair control is called the chair endpoint. It is important to note
that all the conference control capability is managed via a customer’s H.243-standard
compatible equipment and not via AT&T’s service. AT&T’s bridge supports this
capability only as a permissible feature. Therefore, it is important for customers to
understand the Chair Control (H.243) capability when working with their equipment
vendor. AT&T offers an even more robust feature that provides similar functionality
using AT&T’s bridge and a touch-tone phone. This feature is called Universal
Conference Control (UCC) and is described in more detail below. The desired conference
mode must be selected at time of reservation request; otherwise, the default option is
voice activated switching.

Universal Conference Control

UCC is only available on the AVAYA MCU. UCC allows a designated conference
participant to control the conference in a manner similar to Chair Control conference
mode, as described above. An advantage of using UCC is that it allows any designated
user to control the conference simply via a touch-tone phone. UCC is a unique feature
that provides a designated participant on a video call with the ability to change the
conference mode that is in use, in real time – “on the fly.” It essentially allows the
controlling location to dictate the video seen by all other parties. For example, the UCC
feature allows a user to do the following:

   1. Designate a specific site as the broadcast site so that all other sites view the
       speaker. Also, alternate between various sites to change the designated broadcast
       site(s) through a simple touch-tone command.

   2. When Continuous Presence (see below for description) is used, the UCC can
       transition between a split screen image and a full-screen image. This can also
       enable a Continuous Presence conference to achieve 30 fps when at full-screen.

Contract # GS00T01AHD0002
Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

   3. Allows the ability to switch between VAS and UCC-designated broadcast modes.

   4. Permits the controlling location to scan all conference participants to establish a
       “roll call” of endpoints participating in the call.

   5. Provides the ability to drop selected parties from the conference. This is desirable
       when participants are disrupting the conference with background noise, and it can
       also aid in maintaining conference security.

   6. Ability to mute and unmute selected endpoints. For example, a participant can be
       muted if any background noise becomes distracting.

   7. Ability for the controlling location to end the conference by dropping all
       endpoints.

When the UCC feature is requested at time of reservation, the requester will receive, via
fax, the following:

      a two-page user instruction document describing the UCC features and associated
       touch-tone commands (see Attachment D).a reservation confirmation document,
       including the Dial-In telephone number and password in order to activate and use
       UCC during the conference.                     A Sample AT&T Reservation Confirmation is
       shown as Attachment E.

The two documents above will be required to successfully operate the UCC feature
during the conference.

Some additional key points on UCC are as follows:

      No additional equipment is required, just a standard touch-tone phone keypad and
       regular phone line

      UCC is available on H.320 standards calls only using the AVAYA MCU.

10.1.3.1.2            Conference Viewing Options
AT&T offers several conference viewing options. Continuous Presence is a
videoconferencing technique that displays multiple conference sites on one screen.

    Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this proposal.
                                                                                                                    I-10-10
Contract # GS00T01AHD0002
Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

Traditional Continuous Presence splits the screen into four quadrants. Enhanced
Continuous Presence gives you the option of a customized layout from two sites to nine
sites. Full-screen is the default option. Continuous Presence options must be requested at
time of reservation.

   1. Full-screen – Default Option.

   2. Continuous Presence (traditional) – view 4 sites on a single screen.

   3. Continuous Presence (enhanced) – Upper Panoramic – view 3 sites on a single
        screen.

   4. Other Continuous Presence Options Available.

Full Screen

This is the default option set for all conferences, unless another option is specified at time
of reservation. It is also the most common option, especially when combined with VAS.
Full-screen allows you to view the site speaking in a large single site image. When
combined with VAS, all conference participants view the current speaker, and the
speaker views the previous speaker. This option is recommended for use in interactive
meetings or when most of the participants are expected to share information. This option
is also recommended for conferences that require high quality video since Full-screen is
able to achieve 30 frames per second (fps) as long as all other factors allow for 30 fps.

Continuous Presence

This option allows multiple sites to be viewed simultaneously on the same screen. The
screen is split into 4 quadrants, therefore, allowing 4 different locations to be viewed at
one time. This option must be requested at time of reservation. Figure 10.1.3.1.2-1 shows
the screen configuration for the Continuous Presence option.

  Figure 10.1.3.1.2-1. Continuous Presence Option. Use of the Continuous Presence
                     option allows viewing of up to 4 sites at once.
At time of reservation users may also designate any of the four quadrants as a mix of
fixed or variable. Fixed ensures that a certain site will always be viewed by all others in a
specific quadrant. When used in conjunction with VAS, the default is set so that all
quadrants are variable. Variable ensures that the site currently speaking will occupy a
quadrant. It is recommended that variable is maintained for at least some of the quadrants
when the conference size is greater than four sites, so that all speaking participants may
be viewed at some point during the conference.

Conferences using Continuous Presence and VAS:

        Participants are assigned to quadrants as they dial into the conference

        New participants, when added, replace the site that has been quiet the longest

        Attempts are made to place former participants back into the same quadrant it had
         previously occupied

        Any video site can participate in the mix

        May designate any of the four quadrants as fixed (at time of reservation)

        Any sites not viewed in a quadrant can still be heard

        You will always see your site in one of the quadrants (Avaya MCU only).

UCC Feature

When used in conjunction with the UCC feature, a designated conference participant can
transition the conference between full screen (1 image) and Continuous Presence (4
images). This is accomplished simply via a touch-tone phone command (Avaya MCU
only).

Continuous Presence – Upper Panoramic

Sometimes referred to as “Boardroom View,” this option provides a 3-image, upper
panoramic view. This option when requested at time of reservation will provide a larger
panoramic window for one site while another two sites appear below in smaller windows.
At time of reservation you can also specify certain site images to be fixed into a window;
otherwise, the default is set so that the sites will switch into a window when a participant
speaks (via VAS). Figure 10.1.3.1.2-2 shows the screen configuration for the Upper
Panoramic option.

sites may be viewed simultaneously, including a panoramic view of one of the sites.

UCC Feature

When used in conjunction with the UCC feature, a designated conference participant can
transition the conference between full screen (1 image) and upper panoramic view (3
images). This is accomplished simply via a touch-tone phone command (Avaya MCU
only).

       Upper Panoramic (view 3 sites at a time)

       Lower Panoramic (view 3 sites at a time)

       Dual Panoramic (view 2 sites at a time)

       Side-by-Side (view 2 sites at a time)

       Top and Bottom (view 2 sites at a time)

       5 plus 1 (view 6 sites at a time)

       Nine Squares (view 9 sites at a time).

       Others available

Continuous Presence with Presentation Mode:

When Continuous Presence is requested for use with a Presentation Mode conference (as
described in section 13.1.3.1.1), the following will be experienced:

       All viewer sites will view only the Presenter in a full-screen image, while all sites
        are still capable of hearing any other sites

       The Presenter will view a quadrant screen (in a VAS, Fixed-Quadrant, or a
        combination of Fixed and VAS Quadrant arrangement).

Continuous Presence and Frame Rates using the Avaya MCU:

When viewing multiple images on a single screen using a Continuous Presence option,
there is a maximum of 15 fps achieved. In some cases this could impact the quality of the
video call, depending on the application or the expectation. However, when transitioning
a Continuous Presence conference back to a Full-screen image via UCC, 30 fps is
achievable as long as all other factors allow for 30 fps.

Continuous Presence and Frame Rates using the Polycom MCU:

Conferences with the Polycom MCU typically achieve frame rates of 30 fps .

10.1.3.1.3            Speed/Bandwidth Features
Transcoding Feature (available via Polycom/Accord MCUs only)

There is no additional charge for this capability. Transcoding allows videoconferencing
systems with different bit rates, resolution rates, frame rates and audio compression
schemes to conference together without requiring all systems to drop to the lowest
common denominator, and lets all systems perform at their highest capabilities. Users
may experience frame rates (fps) in the mid-20’s.

Speed Matching Feature (available via Avaya MCUs only)

There is no additional charge for this capability. Speed Matching on a H.320 Standards
conference permits sites operating at different data rates to participate on the same H.261
videoconference, without the need for analog speed conversion. Speed Matching employs
a digital translation technology for conferencing between sites of unlike data rates, audio
algorithms and frame rates. For example, a conference size of four sites could have three
locations connected at 384 Kbps and one location connected at 128 Kbps. This feature
can support up to four (4) different speeds on the same conference call.

Please note that for the most part the primary benefit of this feature is that it simply
allows sites at different speeds to participate on the same multipoint video conference
call. It still does not solve some of the quality issues since a Speed Matching conference
is limited to a maximum of 15 fps. In the above example, the site at 128 Kbps essentially
reduces the quality of the conference for all other sites that may have been able to achieve
a higher quality conference at 384 Kbps and 30 fps without the fourth site connected at
128 Kbps.

The following features can also be scheduled in conjunction with Speed Matching:

      Continuous Presence

      UCC

10.1.3.1.4            Call Initiation Options
AT&T offers flexibility in conference initiation to meet the needs of all participants. Sites
may be connected into a conference via either Dial-Out from bridge (AT&T-initiated), or
Dial-In (participant-initiated). Conferences may be billed as either Host Pay for entire
call, or each participant pays for their own leg of the call. Regardless of call type, calls
are billed for connection time of each site to the bridge, including any time prior to the
actual conference start time.

10.1.3.1.5            Conference Assistance
AT&T’s       Video        Bridging        Service        offers      two       options       for     operator-assisted
videoconferences:

   1. Standard Assisted Conferences: with this option an AT&T Conference
       Producer will assist with the connection of endpoints as per the (pre-scheduled)
       reservation request. The Conference Producer will also verify audio and video
       signals with all sites via Meet & Greet, but then will back out of the conference.
       The conference is then monitored in a queue of other conferences. For assistance
       during the conference, participants may call 1-866-843-3606 or 303-415-3552

   2. Dedicated Conference Producer: with this option an AT&T Conference
       Producer is dedicated to the individual conference to provide assistance and
       monitoring throughout the entire call. This option is ideal for those “high-profile”
       meetings that require a special touch. Active monitoring is when the Conference
       Producer remains on the live call after Meet & Greet to proactively monitor audio

                                                                                                                    I-10-16
Contract # GS00T01AHD0002
Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

        and video quality during the conference. Any problems and/or special requests are
        addressed in real-time. Passive monitoring is when the Conference Producer exits
        the live conference and monitors bridge diagnostics only. A direct
        communications phone line extension to the Dedicated Conference Producer is
        also available. The AT&T Conference Producer may also assist by adding or
        dropping endpoints during the conference. An additional charge per hour applies
        for an Dedicated Conference Producer conference.

For either Standard or Dedicated Conference Producer options, locations may be bridged
into a videoconference call as bridge dial-out, dial-in to bridge, or any combination of
dial-out or dial-in call types.

Dial-In to Bridge (Participant-initiated)

This option is available domestically within the U.S. and from over 60 countries. The
countries where service is currently available are listed in Table 13.1.3.4-1. Dial-In offers
users greater flexibility since the participants can dial-in whenever they are ready to join
the conference. Locations dial into the AT&T bridge, each site calling a unique number
pre-assigned to each site at time of conference reservation. Users with switched access
from another carrier must prefix the call with the AT&T PIC, 1010288, before dialing the
bridge number. Callers from non-domestic locations may access the Video Conference
bridge by dialing the prefix “001” prior to dialing the specific number assigned for each
dial-in port as specified in the AT&T reservation confirmation. These dialing instructions
will be included in all training materials for the Video Teleconference Service. For dial-
in calls, separate charges apply for the transport and the bridging portions of the call. The
bridging charges are the same regardless of whether calls originate from either U.S. or
international locations. The transport charges will vary based on the carrier and calling
plan at each location (end-user is directly responsible for payment of transport charges to
their carrier).

Dial-Out from Bridge (AT&T-initiated)

Contract # GS00T01AHD0002
Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

This option is available domestically within the U.S. and to over 70 countries. The
countries where service is available are listed in Table 10.1.3.4-1. Dial-Out offers users
greater ease-of-use since the participants only need to “show up” at the site for the
meeting. The AT&T bridge initiates the call 15 minutes prior to actual conference start
time, and dials out to predetermined sites as specified in the reservation. The conference
host may request a lead-time interval greater than 15 minutes at time of reservation. The
Dial-Out option also allows AT&T to begin proactive troubleshooting in advance of
actual conference start time if there is difficulty connecting to the site. For this call type,
one bundled charge includes both the transport and bridging portions of the call. AT&T
may Dial-Out to an ISDN (H.320) site.

Mixed Dial

Conferences may consist of a mix of both Dial-Out and Dial-In call types depending on
the needs of each participating site.

Meet & Greet

This option is available for Dial-Out, Dial-In, and Mixed Dial conference call types.
AT&T Video Conference Producers greet and introduce each participant as they are
added to the conference, and announce current participants. The technicians are also able
to verify proper conference operation to help ensure a successful call. During call set-up
they will keep participants informed of progress and if, after several unsuccessful
attempts, a site cannot be connected, then AT&T will offer the site an audio-only
connection into the video conference call (via audio add-on capability). Meet & Greet
also provides a level of security to the conference since all participants can be confirmed
or verified.

Audio Add–on Participants

Audio add-on ports – allows users to Dial-In as an audio-only participant on a video
conference call. This option is perfect for users who are on the road or away from video
equipment. Sites without access to videoconferencing equipment may listen to and
participate in a videoconference meeting through the use of a telephone or speakerphone.
The method for non-video sites to access a video conference call is by simply dialing a
specified telephone number provided in the reservation confirmation document and
entering an access code to join the conference.

Proposal to Add Federal Telecommunications Service – Long Distance (FTS-LD)

      Up to 4 sites – as part of the standard service, up to four audio ports may be added
       to a video conference call. On the reservation request form, simply provide the
       number of required audio participants (1-4 participants)

      5 or more sites – can also be supported; however, for quality purposes they will be
       connected to an audio conference bridge - which is then connected to the video
       conference bridge. On the reservation request form, simply provide the number of
       required audio participants.
