ISDN Information
If you are not connected to an internal phone system often, called a
PBX, you need to connect the ISDN cables from your ViewStation
IMUX module to the NT-1 device. An NT-1 device is used with the
North American ISDN U interface.
The lights on the IMUX indicate whether or not the ISDN lines are
connected properly. The lights, however, do NOT indicate that the
SPIDs, switch type, and ISDN numbers have been correctly entered
into the ViewStation.
The following are sample NT-1 settings. For more detailed
diagnostic information, see the manual that was shipped with your
particular NT-1 device.
Sample NT-1 Settings
On an ADTRAN NT-1 ACE ISDN termination unit, you should see
the following status lights when your ISDN lines are properly
connected.
The dip switches should be set as follows:
Status
Ready
Error
Power
ON
OFF
