The repeater can be configured to measure the antenna isolation on a certain timepoint of the day
(configured using attributes AIE and AIT). If antenna isolation is too low (as configured with attribute
ALA AIM), an alarm is triggered.

Command Attributes”
The antenna isolation is measured using the BCCH downlink and a second listener channel.
By default, downlink chain 1 and 2 settings are used for the antenna measurements. If only one chain is
enabled in the repeater, or if measurement should be done on other channels, this attribute can be used to
configure the alternate channels.
enabled in the repeater, or if measurement should be done on other channels, this attribute can be used to
configure the alternate channels.
Format:
X Y
X is the BCCH channel, and Y is the second channel used in the measurements.
If configured to 0, same as configured in CHA 1 and 2 is used.
Example:
GET AIC
Reply:
0 122
means that BCCH channel used is the one used in chain 1, but the listener channel is 122.
Example:
SET AIC 46 51
configures the BCCH used during measurements to 46, and listener channel to 51.
Note!
Antenna isolation is not measured in Fiber Optic repeaters and repeaters CSFT18922 and
