Step Action
6
Verify that the correct channel number for the selected carrier is shown in the Carrier # Channels
box. If it is not, obtain the latest bts–#.cdf (or bts–#.necf) and cbsc–#.cdf files from the CBSC.
NOTE
If necessary, the correct channel number may be manually entered into the Carrier # Channels box.
7 If at least one MCC was selected in Step 3, select the appropriate transfer rate (1 = 9600, 3 = 9600 1X)
from the drop–down list in the Rate Set box.
NOTE
The rate selection of 3 is only available if 1X cards are selected for the test.
8 If Verify BLO is to be used during the calibration, leave the checkbox checked (default).
9
If Single–Sided BLO is to be used during the calibration, click on the checkbox.
* IMPORTANT
Single–Sided BLO should only be used for primary BBXs. Do not check the box when calibrating the
redundant BBX.
10 In the Test Pattern box, select the test pattern to use for the calibration from the drop–down list (refer
to “Test Pattern Drop–down Pick List” under “TX Calibration and the LMF” in this section).
11 Click OK to display the status report window followed by a Directions pop-up window.
12 Follow cable connection directions as they are displayed.
– When the calibration process is completed, results will be displayed in the status report window.
13 Click OK to close the status report window.
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 connection and re–run the calibration. If the
calibration fails again, note specifics about the failure, and refer to
Chapter 6, Troubleshooting.
