The BBX then de-keys and, if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then repeated. Upon completion of the test, the
OCNS is disabled on the specified MCC/CE.
See Table 4-1 to perform this test.

RX Frame Error Rate (FER) Acceptance Test
This test verifies the BTS FER on all traffic channel elements currently
configured on all equipped MCCs (full rate at 1% FER) at an RF input
level of –119 dBm [or –116 dBm if using Tower Top
Amplifier (TMPC)]. All tests are performed using the external calibrated
test set as the signal source controlled by the same command. All
measurements are via the LMF.
The Pilot Gain is set to 262 for each TX antenna, and all channel
elements from the MCCs are forward-link disabled. The BBX is keyed
