1X SC 4812T BTS Optimization/ATP Software Release 2.16.1.x
FIELD TRIAL
1-6
Each C-CCP shelf BBX board is optimized to a specific RX and TX
antenna port. (One BBX board acts in a redundant capacity for BBXs
1-12, and is optimized to all antenna ports.) A single value is generated
for each path, thereby eliminating the accumulation of error that would
occur from individually measuring and summing the gain and loss of
each element in the path.
When to Optimize
New Installations
After the initial site installation, it must be prepared for operation. This
preparation includes verifying hardware installation, initial power-up,
download of operating code, and Clock Synchronization Module (CSM)
verification.
Next, the optimization is performed. Optimization includes performance
verification and calibration of all transmit and receive RF paths, and
download of accumulated calibration data.
After optimization, a series of manual pre-ATP verification tests are
covered that address alarm/redundancy tests.
After manual pre-Acceptance Test Procedure (pre-ATP) verification
tests, a series of manual ATP CDMA verification tests are covered using
the actual equipment set up. An ATP is also required before the site can
be placed in service.
Site Expansion
Optimization is required after expansion of a site.
Periodic Optimization
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
Repaired Sites
Refer to Appendix C for detailed basic guideline tables and detailed
Optimization/ATP Test Matrix outlining the minimum tests that must be
performed anytime a BTS subassembly or RF cable associated with it is
replaced.
