Exception Handling
In the event of a failure, the calibration procedure displays a FAIL
message in the status report window and provides information in the
Description field.
Re–check the test setup and connections and re–run the test. If the tests
fail again, note specifics about the failure, and refer to Chapter 6,
Troubleshooting.
Create CAL File
The LMF Create Cal File function gets the BLO data from BBXs and
creates/updates the CAL file for the BTS. If a CAL file does not exist a
new one is created. If a CAL file already exists it is updated. After a
BTS has been fully optimized a copy of the CAL file must exist so it can
be transferred to the CBSC. If TX calibration has been successfully
performed for all BBXs and BLO data has been downloaded, a CAL file
will exist. Note the following:
S The Create Cal File function only applies to selected (highlighted)
BBXs.
CAUTION
Editing the CAL file is not encouraged as this action can cause
interface problems between the BTS and the LMF. To manually
edit the CAL file you must first logout of the BTS. If you
manually edit the CAL file and then use the Create Cal File
function the edited information will be lost.
Prerequisites
Before running this procedure, the following should be done:
S LMF is logged into the BTS
S BBXs are OOS_RAM (yellow)
