Cause
The system goes to "sleep" mode
after 3 minutes of inactivity.
Only one monitor is enabled.
The monitors are connected to the
same output. The monitor has a
composite as well as an S-Video
output.
The network line transmission
errors or IP LAN traffic is too high.
Check the error count under the
Diagnostics screen or try a lower
speed IP call.
Only one 64 Kbps channel is
connecting in your call.
Lots of motion in the picture you
are receiving.
Chapter 8 - Troubleshooting
Solution
Pick up the remote control to wake up
the system.
Enable the ViewStation FX or
VS4000 for two monitors on the
Monitor Setup screen.
Connect Monitor 2 to the Monitor 2
connection on the rear panel of the
ViewStation FX or VS4000.
Check your system using the Near
End Loop test under the
Diagnostics screen. If the picture
does not freeze, tell the far site to
perform the same test. If the picture
freezes, there are line errors on your
ISDN lines.
You can also test this by placing a
video call to an ISDN loopback
number provided by your service
provider.
Check the ISDN number of the far
site. Ask the far site to call your site.
A background with less motion
provides a better, smoother video
picture.
