The field descriptions for each of the decoded messages are given in the "CALL
DATA Screen Message Field Descriptions" on page 170
.
When the CALL DATA screen is displayed and the Call Processing Subsystem is
in the connected state, the Test Set constantly monitors the mobile station’s
transmitted carrier power. If the power falls below 0.0005Watts, the error
message
RF Power Loss indicates loss of Voice Channel will be
displayed and the Test Set will terminate the call and return to the active state.
NOTE: In order to ensure that the Test Set makes the correct decisions regarding the presence of the
mobile stations’s RF carrier, the Test Set’s RF power meter should be zeroed before using the
Call Processing Subsystem. Failure to zero the power meter can result in erroneous RF power
measurements. See "Conditioning the Test Set for Call Processing" on page 141 for
information on zeroing the RF Power meter manually.
[] Access
When lit, the Access annunciator indicates the Test Set is signaling the mobile
station with command information on the forward voice channel. This is a
transitory state.
The Test Set’s speaker is turned off when in the access state. This is done to
eliminate any possible audio feedback which may occur if the mobile station’s
microphone is open.
