When to Optimize
New Installations
The following operations and optimization/test actions should be
accomplished for a new BTS or frame installation:
1. After the initial site installation, it must be prepared for operation.
This preparation includes verifying hardware installation, initial
power–up, downloading of operating code, verifying GPS operation,
and verifying transmit and receive paths.
2. Next, the optimization is performed. Optimization includes
performance verification and calibration of all transmit and receive
RF paths, and download of accumulated calibration data.
3. A calibration audit of all RF transmit paths may be performed any
time after optimization to verify BTS calibration.
4. After optimization, a series of manual pre–Acceptance Test
Procedure (ATP) verification tests are performed to verify
alarm/redundancy performance.
5. After manual pre–ATP verification tests, an ATP is performed to
verify BTS performance. An ATP is also required to demonstrate
regulation compliance before the site can be placed in service.
Site Expansion
Optimization is required after expansion of a site with additional BTS
frames.
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 a detailed FRU Optimization/ATP Test Matrix
outlining the minimum tests that must be performed any time a BTS RF
subassembly or cable associated with an RF path is replaced.
