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, the BTS 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

NOTE

Refer to Appendix B 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.
