Table 1. Determining Termination Settings

2 Set the Required Termination

You must set the NT1 and your ISDN devices to the termination

value indicated by Table 1.

Set the termination on your ISDN devices to the value specified

under “Termination—Other Devices.” The manuals which came

with your ISDN devices can tell you how to do this.

To set the termination on the NT1, you manipulate five small switches

on the rear of the unit, shown in Figure 1, to match the settings given

under the heading “NT1 Switch Settings” in Table 1.
