Multi-Point Viewing Modes
You can select four different viewing modes for the multiple sites in
a multi-point call:
•
•
•
•
Automatic (Auto)
Discussion
Presentation
Full Screen
The default viewing mode is Automatic (Auto), which automatically
switches between Discussion and Presentation modes, depending
on the conversational style of the multi-point call. Below is a
description of each mode:
Auto: In Auto mode, the ViewStation determines the optimal viewing
mode based on the interaction between the sites in the video call. If
more than one site is talking at the same time, the ViewStation uses
Discussion mode. If one site is talking uninterrupted, the ViewStation
uses Presentation mode. The ViewStation takes about 15 seconds
to decide whether there is a single presenter before it switches to
Presentation mode. If one of the far sites interrupts the presenter for
several seconds during Presentation mode, the ViewStation
immediately switches to Discussion mode.

Discussion: In Discussion mode, all of the sites in the video call can
see everyone in the call at the same time. This feature is sometimes
referred to as Continuous Presence. If using one television monitor
with the ViewStation, when the call connects, each site is displayed
on the screen in a separate window. The near site appears in the
picture-in-picture (PIP) window at the lower right of the screen. If two
television monitors are used in a four-way video call (yourself and
three sites), you appear on the second television monitor. The far
sites appear in three separate windows on the first television
monitor. If you are using two television monitors in a three-way video
call, each far site appears full-screen on each of the two monitors,
and you appear in the PIP window on the main television monitor.
Presentation: In Presentation mode, which is also called
voice-activated switching, the person who is speaking appears full
screen to the far sites. If you are using one television monitor, the
speaker appears full screen on your monitor. Your picture
automatically appears in the PIP window when you raise the remote
control. If you are using two television monitors, the person who is
speaking appears on the main television monitor. The other sites
appear in separate windows on the second television monitor.
Full-Screen: In Full-Screen mode, the speaker appears full screen
to all sites. You can easily switch viewing modes either before or
during a multi-point call. To switch modes:

NetMeeting Application Sharing
To use NetMeeting application sharing, file transfer, and
whiteboarding, a PC must be connected to your ViewStation directly
or via the LAN. NetMeeting data is transmitted via the H.323 IP
network. The bandwidth used is dynamically allocated so that when
NetMeeting is not sending data, the bandwidth used returns to the
video data.
Note T.120 application sharing, file transfer, and whiteboarding
are supported for NetMeeting 3.0 when used with two
ViewStations. You must have the same version of
NetMeeting installed on both ends of the videoconference.
H.323 Video Calls with NetMeeting
H.323 video calls can be placed to and from a PC using NetMeeting
2.11 or 3.0+. The line speed of a video call from NetMeeting to a
ViewStation depends on the bandwidth setting in NetMeeting. The
maximum line speed for NetMeeting calls is:
•
•
Cable, xDSL, or ISDN = 128 Kbps
LAN = 384 Kbps (maximum speed of Microsoft NetMeeting).
Calls from a ViewStation to NetMeeting must be at line speeds
greater than 64 kbps. Application sharing with NetMeeting cannot be
done in an H.323 call with a ViewStation.
System Information and Remote Management
The ViewStation has an embedded Web server that provides for

You can perform a software upgrade to the far site over your H.320
line during a call. Upgrading works best at 384 Kbps.
Caution Do not power off the ViewStation during the software
update process. If you power off a ViewStation during the download
process, the ViewStation reverts to its original software version.
The ViewStation automatically restarts once the software upgrade
process is complete.
Complete the following steps to upgrade a system:
1. Place a video call to the far site ViewStation.
2. Select System Info > Admin Setup > Security and write down
the passwords that appear on the Security screen of the site

The Advanced Network Statistics screen displays detailed
information about the status of your call. Transmit and receive
speeds are displayed for both audio and video during a video call.
Call Status
The Call Status screen allows you to determine if one of the far
site’s ISDN channels consistently fails to connect. If you highlight
any of the call progress indicators, the corresponding line number
appears. You can then compare this number to the number you
need to dial. Check the status code for each line if you need to
troubleshoot line problems. See "ISDN Information" on page 203.

Network Address Translation
Network Address Translation (NAT) lets home office or small
network environments use internal IP addresses for the devices
within the network, while using one external IP address to
communicate with the outside world (Wide Area Network). However,
many Small Office Home Office (SOHO) routers provide NAT
services that are not fully H.323 compliant.
Therefore, this solution is provided to enable the user make calls
outside the internal network.
Note At this time, it is not possible to make video conferences
calls within the internal network when using the NAT setting.
To make video conferencing calls within the network when using this
solution, simply de-select the System is behind a NAT option and
make the call. Re-select the System is behind a NAT option to
re-activate this feature and make external calls.
Before You Start Configuring NAT
1. Determine your NAT’s external (WAN) IP address. This is the
address assigned to your NAT’s external interface (connected to
the Internet).
2. Determine the IP address of your ViewStation. This can be
found on the System Information screen.
Setting up NAT
1. Go to the Quality of Service and Firewalls screen (System
Info > Admin Setup > LAN/H.323 > H.323 > QoS).
2. Select Use Fixed Ports.
3. Select System is behind a NAT.

4. Enter the NAT’s external IP address into the NAT outside
(WAN) address field.
Write down the Fixed TCP and UDP port numbers displayed on
this screen. These numbers typically are the following default
numbers:
TCP: 3230 to 3231
UDP: 3230 to 3235
5. In your NAT, reset the fixed ports from step 4 to be permanently
open, and redirect them to the IP address of your ViewStation.
6. To accept incoming calls, open and redirect port 1720 to the IP
address of your ViewStation.

V.35 Technical Information
Crypto Resync
If a cryptographic encoder/decoder is connected between the
ViewStation and the network, it may require a resynchronization
signal from the ViewStation. This is a signal indicating that the
ViewStation has lost video synchronization due to a network
problem and requires that the cryptographic encoder/decoder
resync with the equipment at the other end of the connection.
To enable this feature select System Info > Admin Setup >
Security. When you select the Crypto Resync option, the Crypto
Resync Pulse screen appears.
On this screen, you can enable crypto resync, set the time between
pulses (in seconds), and set the pulse width (in milliseconds).
If the ViewStation is in a call and it loses H.320 synchronization, it
continuously sends the resynchronization pulses at the specified
rate with the specified pulse width until H.320 regains
synchronization.
The resync pulse is output on the Ready-To-Send or RTS signal. If
this feature is enabled, the RTS signal no longer functions as the
RTS signal. Most installations that use encryption equipment require
a custom cable. The cable should be designed to route the RTS
signal from the ViewStation to the appropriate resync input on the
encryption equipment. The encryption equipment can get its RTS
input from the ViewStations DTR output or by wiring this input to an
always-high tie-off. In this nondialed mode, the DTR output and RTS
output act exactly the same. Refer to the V.35 State machine
descriptions in this appendix for more information on these signals.

that identifies a computer connected to the
Internet. Every computer that is connected to
the Internet must have unique IP address.
Currently, an IP address consists of four
sections separated by periods. Each section
contains an 8-bit value represented as a
number ranging from 0 to 255. The allocation
of these IP addresses follows a two-level
architecture that assigns IP numbers to a
network and the hosts on that network.
IP Precedence
IP precedence tells downstream networking
equipment (mainly routers) to give priority to
audio and video data. It marks each audio
and video packet with a user-defined
precedence (the default is 4). Only audio,
video, and far-end camera control-packets
are marked. Control packets (such as
opening and closing of connections,
channels, etc.) are not marked with
precedence.
The user may specify any one of 8 levels
(0-7) of precedence with 0 signifying no
priority and 7 signifying the highest priority.
It is recommended by networking equipment
vendors to use 4 for multimedia data. By
default, IP precedence is disabled by most
routers and is not enabled on the Internet.
ISDN

Broadband ISDN (2 Mbps - 600 Mbps). ISDN
usually consists of 2 B channels of 64 Kbps,
and one D channel of 16 Kbps on one RBI

for out-of-band signaling that does not
interfere with the flow of information going
