Cause
Call progress circles only
show blue or yellow.
Call progress circles do not
turn green, or remain blue
after the first channel
connects.
System restarts over and over
again.
Speeds do not show when
selecting the speed icon.
DHCP Client is ON and no
DHCP server is available.
LAN cable is connected to the
PC port.
Bad LAN cable.
There is a firewall between
your PC and your
ViewStation.
Your PC is on a different
subnet and there is router
between you and your
ViewStation.
Wrong password.
Too many managers logged
into the system.
Solution
Start by calling the far-site at 1x64 or
2x64K. This will verify if the primary
number is correct. If these calls complete, try
256K then 384K.
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.
Defective cable between the IMUX and
ViewStation. Check that the green lights on
each ISDN card are on and that the green
light on the top of the IMUX is on (red on
older units). The cable from the IMUX to the
ViewStation is a straight RJ-45 x RJ-45 cable.
Bad power supply.
Add line speeds by going to the IMUX
Dialing Speeds screen.
Contact your network administrator.
Connect the LAN cable to the LAN port on
the rear of the ViewStation.
Check the light on the back of the
ViewStation. You should have a steady
green light to indicate a connection to the
LAN and a flashing orange light to indicate
LAN traffic.
Consult your network administrator.
Change your PC or ViewStation Subnet
mask and IP address so that they are both on
the same LAN or subnet.
Enter the correct password. Note: The
default password is "admin".
Only two system managers are allowed at
any one time. To log everybody else out,
restart your ViewStation.
