RFDS Path Calibration should be performed at initial BTS installation AND after replacement of the RFDS FRU.
RFDS Path Calibration is NOT required for other FRU replacement but may be used as an additional fault isolation tool.

* Perform if necessary for additional fault isolation, repair assurance, or site certification.
1 Perform on all carrier and sector TX paths to the C–CCP cage.
2 Perform on all carrier and sector RX paths to the C–CCP cage.
3 Perform on all primary and redundant TX paths of the affected carrier.
4 Perform on the affected carrier and sector TX paths. (BBXR replacement affects all carrier and sector TX
paths.)
5 Perform on the affected carrier and sector RX paths. (BBXR replacement affects all carrier and sector RX
paths.)
6 Perform on all RF paths of the affected carrier and sector (RFDS replacement affects all carriers.)
7 Perform with redundant BBX for all sectors on all carriers.
8 Verify performance by performing on one sector of one carrier only.
