ISDN Information
If you are not connected to an internal phone system, called a PBX, you will need to connect the ISDN cables from your ViewStation to the IMUX module to the NT-1 device, which is connected to an ISDN wall jack. Once everything is connected, their lights will indicate whether or not they 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.
If you are outside the United States or Canada, your service providers or PTTs generally provide the network termination (NT-1) device.
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:
