In–Service Calibration for 1X
Upgrade
This feature does NOT have fault tolerance at this time.
The system has no safe–guards to prevent actions which
will put the BTS out of service. If possible, perform this
procedure during a maintenance window.
Follow the procedures in this section precisely, otherwise
the entire BTS will most likely go OUT OF SERVICE.
At the CBSC, only perform operations on expansion
hardware when it is in the OOS_MANUAL state.
The operator must be trained in the LMF operation prior to
performing this procedure.

Prerequisites
S Expansion hardware has been added in the CBSC database, and the
CDF file has been generated.
S The expansion devices have been inserted into the C–CCP cage and
are in the OOS_MANUAL state at the CBSC MM.
S The site specific CDF (with the expansion hardware) and CAL files
have been loaded onto the LMF.
S The LMF has the same code and dds files as the CBSC to download.
Do not download code or data to any cards other than those
you are working on. Downloading code or data to other
cards will take the site OUT OF SERVICE.
The code file version numbers must match the version
numbers required for the upgrade cards (refer to NO TAG).
If the numbers do not match, the site may go OUT OF
SERVICE.
It is mandatory that the bts–#.cdf and cbsc–#.cdf
files on the LMF computer for this BTS are copies of the
corresponding files created in the CBSC database (see
NO TAG).
The CAL file loaded on the LMF computer for this BTS
must have come from the CBSC.
