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 130 for
information on zeroing the RF Power meter manually.
