iPower Collaboration System Tips and Troubleshooting
58
Problem
Slow video image in an ISDN call
Camera is in Standby mode
(powered down)
No output from VCR
Corrective Action
An ISDN line sends signals on one or
more B channels. If the call is using
Note
only one channel, the video image
becomes slow.
• Check to be sure that the call connected at
the rate you requested.
- With the call still connected, double-click
the Conference Statistics icon on
the taskbar in the lower right-hand corner of
the screen.
- Check the Key frames. A large number or a
steadily increasing number in this field
indicates a network quality problem. Redial
the call or try connecting at a lower rate.
• Minimize and then maximize the
Collaboration application, click a mouse
button, press a remote control button, or clear
the screen saver.
• Turn off the camera (if necessary), unplug the
video cable, and then plug it in again.
• From the Hardware Diagnostics application,
click Test Video and attempt to control the
camera.
• Restart the collaboration system.
• If the problem persists, call for service.
• Make sure that all power, audio, and video
cables to and from the system, display, and
VCR are correctly installed and secure.
• If your VCR requires that you select an output,
choose the RCA or Composite output.
• Play a known good VCR tape. If the tape will
not play, perform the following steps:
1. Restart the collaboration system.
2. From the Hardware Diagnostics
application, click Test Video and select the
VCR Video Source option.
3. Play a known good VCR tape again. If the
tape still will not play, call for service.
