the Service Monitor onto the system. Pressing the PTT switch makes a call, releasing the PTT
clears it. The microphone is plugged into the ACCESSORY socket on the front of the Service
Monitor.
Data displays
Introduction
Note...
Restricted access.
Access to this facility is protected by password control. Ericsson GE have imposed this restriction,
due to the potentially confidential nature of the information which can be decoded. The
[DATA]
key is not displayed until the facility is unlocked.
To enable the data display mode, press the
[DATA]
key at the left-hand side of the screen.
The data display mode allows you to view the data messages which are sent between the Service
Monitor and the repeater. You can rapidly identify incorrect bits sent by the repeater, which may
have caused a test to fail. The data displays can also serve as an educational or reference facility
for users who are unfamiliar with trunking signaling.
