3.4 Setting Up on the Bench
Before installing the base station in the on-site cabinets or racks, it is a good
idea to set it up on the bench. You can then verify that it is operating
correctly, and tune it if necessary. You can also customize its configuration
for the installation it is destined for and verify that the configuration is
correct. An important aspect of that configuration is the base station’s IP
address. The base station comes with a default IP address but needs to be
given the IP address required for its position in the Tait P25 Network.
Using a Calibration
and Test Unit
A Calibration and Test Unit (CTU) can be of great assistance when
confirming operation and when tuning and calibrating the base station.
Connect the CTU to the base station or gateway as shown in Figure 3.3.
