TESTING

Select the PROJ 25 TRK mode by placing the

cursor in the "Mode:" field in the Display

Zone located at the top of the screen. Use the

PROJECT 25 TRK softkey to select the

PROJ 25 TRK mode. A screen similar to

Figure 25-1 appears.

This section of the manual contains

information on testing Project 25 trunked

radios using the R2670 or R2625 Digital

Communications System Analyzer with the

Project 25 Trunking Option. Two types of

subscriber tests are defined:

Registration/Call Alert and Dispatch Voice;

and two types of base station/repeater test are

defined: BASE and BER

When the display zone "Mode:" is set to PROJ

25 TRK, the R2670 will configure itself to

emulate a Project 25 basestation.
