FRU Optimization/ATP Test Matrix
FEB 2005 1X SC 4812T Lite BTS Optimization/ATP C-1
PRELIMINARY
Usage and 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.
Re–Optimization Actions listed for any assembly detailed
in the tables below must be performed anytime an RF
Cable associated with it is replaced.
NOTE
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:
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/Acceptance Test Procedure to
understand which Test Equipment Set–ups, Calibrations,
and BTS Site preparation will be required before
performing the table number procedures referenced.
NOTE
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.
S If the TX Path Calibration Audit fails, the entire RF Path Calibration
will need to be repeated.
S If the RF Path Calibration fails, further troubleshooting is warranted.
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.
NOTE
When the CIO is replaced, the SCCP Cage remains powered up. The
BBX Cards 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.
