Version:
1.0
Format:
<Rack1><Rack2><Rack3><Rack4>
where
<Rack1> is status of the input signal level as measured in the Splitter Board of the first
rack (Master Rack).
<Rack2> is status of the input signal level as measured in the Splitter Board of the
second rack (Slave Rack).
<Rack3> is status of the input signal level as measured in the Splitter Board of the third
rack (Slave Rack).
<Rack4> is status of the input signal level as measured in the Splitter Board of the fourth
rack (Slave Rack).
where
0 means status is OK
1 means status is ERROR
- (dash) means data is not available (not yet measured or communications error with
Splitter Board).
Example:
GET ILD
Reply:
010-
meaning that input signal level is outside configured interval in the second rack, and that
fourth error is not installed, or there is a communications error with fourth rack.
Note 1! Input signal level is measured after attenuation, to ensure that desired level is
distributed throughout the repeater system.
Note 2! To configure downlink attenuation, refer to attribute ATD. To read out actual
received input levels, refer to attribute ILV and to set input signal alarm thresholds use
attribute ALA ILD.
8.4 ILV – Input Levels Downlink
Displays RF input levels in the downlink.
8.4.1 Usage
Attribute Type: Read-Only
This attribute replies with the input signal level to the system in the downlink path. This
can be used to adjust the downlink levels for optimal performance. Signal is measured
after the downlink attenuator. This level is also used when configuring threshold for the
Input Level Downlink (ILD) alarm.
Format:
<ILV:1> <ILV:2> <ILV:3> <ILV:4>
where
<ILV:1> .. <ILV:4> is the input signal level in dBm with one decimal tolerance for
Splitter Board in rack 1 to 4.
If input power is lower than lowest detectable signal, '<x' is replied instead, where x is
lowest detectable input signal level.
If rack is not installed, or there is a communications alarm with Splitter Board, a '-' (dash)
is reported in corresponding position.
Example:
GET ILV
Reply:
2.0 <-5.0 - -
which indicates that rack one has an input signal level after attenuation of 2.0 dBm, rack
2 has an input signal level of less than -5.0 (lowest detectable) while rack 3 and 4 are not
installed, or there is a communications error with corresponding rack.
