ATP Test Options
ATP tests can be run individually or as one of the following groups:
S All TX: TX tests verify the performance of the BTS transmit
elements. These include the GLI, MCC, BBX, trunking modules, the
LPAs, 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 modules, 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, be sure the following have been
completed:
S BTS has been optimized (BBXs 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 CSMs, GLIs, BBXs, MCCs and TSU (if the RFDS is installed) have
correct code and data loads.
S Primary CSM and GLI are INS_ACT (bright green).
S MCCs are INS_ACT (bright green).
S No BBXs are keyed (transmitting).
S BBXs 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.
WARNING
1. All transmit connectors must be properly terminated for all
ATP tests.
2. Before the FER is run, be sure that one of the following is
done:
– All transmitter connectors are properly terminated
OR
– All LPAs are turned OFF (circuit breakers pulled)
Failure to observe these warnings may result in bodily injury or
equipment damage.
