3.10.3.1 — RSSI monitoring point
The RSSI is available on a connector used to manually point the antenna on the field.
The higher the voltage, the higher the RSSI and the better aligned the antenna is. The RSL
is measured using a is used a voltmeter connected to the MPT with a service kit cable.
1.Without any received signal (Tx mute on the remote MPT for example), the RSL value displayed may be
more than -100 dBm. This depends on the channelization/modulation settings.
