Automated Acceptance Test Procedure – continued
4-2 1X SC 4812T Lite BTS Optimization/ATP FEB 2005
PRELIMINARY
In the unlikely event that the BTS passes these tests but has a Forward
Link problem during normal operation, the CFE should then perform the
additional TX Tests for troubleshooting: TX Spectral Mask, TX Rho,
and TX Code Domain.
ATP Test Options
ATP Tests can be run individually or as one of the following groups:
S All TX: TX Tests verify that the performance of the BTS Transmit
Elements. These include the GLI, MCC, BBX, Trunking Modules, the
LPA Modules, and passive components including Splitters,
Combiners, Bandpass Filter(s), and RF Cables.
S All RX: The RX Test verifies the performance of the BTS Receive
Elements. These include the MPC, EMPC (for Companion Frames),
BBX, MCC, GLI Cards, and the passive components including RX
Filters and RF Cables.
S All TX/RX: Executes all TX and RX Tests.
S Full Optimization: Executes the TX Calibration, downloads BLO,
and executes the TX Audit before running all TX and RX Tests.
ATP Prerequisites
Before attempting to run any ATP Tests, ensure that the following have
been completed:
S BTS has been optimized (BBX Cards calibrated and BLOs
downloaded) (Chapter 3)
S The carrier(s) and/or sector(s) to be tested have been taken out of
service at the CBSC.
S LMF is logged into the BTS.
S CSM Cards, GLI Cards, BBX Cards, MCC Cards and TSU (if the
RFDS is installed) have correct code and Data Loads.
S Primary CSM and GLI are INS_ACTIVE (bright green).
S MCC Cards are INS_ACTIVE (bright green).
S No BBX Cards are keyed (transmitting).
S BBX Cards are OOS_RAM (yellow).
S Test Cables are calibrated.
S Test Equipment has been selected, warmed–up 60 minutes, and
calibrated.
S GPIB is on.
S BTS Transmit Connectors are properly terminated for the test(s) to be
performed.
