after the first channel
connects.
Go to the call status screen. Highlight each
of the circles for each of the channels dialed.
The number dialed for each channel will be
displayed as you highlight the
corresponding circle. Make sure that the far-
site has entered the number for each of their
ISDN lines correctly. The numbers for Line 1
- Line 4 should correspond with connections
1 - 4 on the IMUX.

System restarts over and over
again.
Defective cable between the IMUX and
ViewStation. Check that the green lights on
