indicating that rack 1 and 2 have attenuation set to 6 dB, rack three to 9 dB and fourth
rack is not configured.
Format on setting parameters:
SET ATD <Rack K> <Atten X> [<Rack L> <Atten Y>] [<Rack M> <Atten Z>]
[<Rack N> <Atten W>]
where
<Rack K> is the rack selector (1..4)
<Attenuation X> is downlink attenuation to set in rack K. Interval is 0 to 21 dB in 3 dB
steps. Optionally attenuation in rack L to N can be set at the same time.
Example:
SET ATD 2 9 3 9
sets attenuation in rack 2 and 3 to 9 dB.
8.2 ATU – Attenuation Uplink
Reads and configures the attenuation in the uplink path.
8.2.1 Usage
Attribute Type: Read and Write
The attenuation in the uplink path is used to configure the system according to downlink
gain settings to get a well balanced system. The attenuation is set in the combiner board.
Format on getting parameters:
<Attenuation:1> <Attenuation:2> <Attenuation:3> <Attenuation:4>
where uplink attenuation for the different racks 1-4 are displayed. If rack is not installed,
a '-' (dash) is reported in corresponding position.

Format on setting parameters:
SET ATU <Rack K> <Atten X> [<Rack L> <Atten Y>] [<Rack M> <Atten Z>]
[<Rack N> <Atten W>]
where
<Rack K> is the rack selector (1..4)
<Attenuation X> is uplink attenuation to set in rack K. Interval is 0 to 21 dB in 3 dB
steps. Optionally attenuation in rack L to N can be set at the same time.
Example:
SET ATU 2 9 3 9

8.3 ILD – Status of Input Level Downlink
Displays status of the input power level in the downlink.
8.3.1 Usage
Attribute Type: Read-Only
The controller constantly monitors the input signal level to the rack in the downlink path.
If input signal level is below configured threshold, this means that output from the
repeaters has dropped too and that desired coverage is not achieved. This causes an alarm
to be triggered.
This attribute is used to read status of the Input Level alarms.
