FRU Optimization/ATP Test Matrix
Usage & Background
Periodic maintenance of a site may also mandate re–optimization of
specific portions of the site. An outline of some basic guidelines is
included in the following tables.
NOTE
Re–optimization steps listed for any assembly detailed in the
tables below must be performed anytime an RF cable associated
with it is replaced.
Detailed Optimization/ATP Test Matrix
Table C-1 outlines in more detail the tests that would need to be
performed if one of the BTS components were to fail and be replaced. It
is also assumes that all modules are placed OOS–ROM via the LMF
until full redundancy of all applicable modules is implemented.
The following guidelines should also be noted when using this table:
NOTE
Not every procedure required to bring the site back in service is
indicated in Table C-1. It is meant to be used as a guideline
ONLY. The table assumes that the user is familiar enough with
the BTS Optimization/ATP procedure to understand which test
equipment set ups, calibrations, and BTS site preparation will be
required before performing the Table # procedures referenced.
Passive BTS components (such as the bandpass filters and 2:1
combiners) only require a TX calibration audit to be performed in lieu of
a full path calibration. If the TX path calibration audit fails, the entire RF
path calibration will need to be repeated. If the RF path calibration fails,
further troubleshooting is warranted.
NOTE
If any significant change in signal level results from any
component being replaced in the RX or TX signal flow paths, it
would be identified by re–running the RX and TX calibration
audit command.
When the CIO is replaced, the SCCP shelf remains powered up. The
BBX boards may need to be removed, then re–installed into their
original slots, and re–downloaded (code and BLO data). RX and TX
calibration audits should then be performed on the affected carrier
sectors.
