6.4 – Operational Examples
The following give examples of how to configure the NICA X for different scenarios.
Example 1
The Primary service is provided by the NICA X using an X21 line and the Reserve service is using ISDN IMUX on 2
channels (see figure section 7.3 backup diagram). In this case both units must be a NICA X. We shall call the two
units Studio Site Unit and Transmitter Site Unit. (These are example names as the units may not actually be at
these locations as they could be between two Radio Station sites for example). The Transmitter Site will dial the
ISDN calls when switching to Reserve.
The units are programmed as follows :
Parameter Transmitter Site Unit Studio Site Unit
Backup Enable BACKUP BACKUP
Primary Mode 8. APT X21 256K-S 8. APT X21 256K-S

The following description is of the Transmitter Site Unit. The Studio Site Unit would be very much the same but
without making the ISDN calls.
