Error −1310 Timeout occurred while attempting to alert Mobile.
Indicates that the simulated Base Station’s internal timer expired before receiving a
response from the mobile station during an alert attempt. The internal timer is set to
20 seconds when the alert order is sent to the mobile station.
Error −1311 RF power loss indicates loss of Voice Channel.
When the CALL CONTROL screen is displayed and the Call Processing
Subsystem is in the Connect state, the host firmware constantly monitors the
mobile station’s transmitted carrier power. If the power falls below 0.0005Watts
the simulated Base Station will terminate the call and return to the Active state.
This error message is displayed if the host firmware has detected that the mobile
station’s carrier power has fallen below the 0.0005Watts threshold. The call is
dropped and the Call Processing Subsystem returns to the
Active state.
NOTE: In order to ensure that the host firmware makes the correct decisions regarding the presence
of the mobile stations’s RF carrier, the Test Set’s RF power meter should be zeroed when
first entering the Call Processing Subsystem (that is - the first time the CALL CONTROL
screen is selected during a measurement session). Failure to zero the power meter can result
in erroneous RF power measurements. See “Using the Analog Call Processing Subsystem”
chapter in the HP 8924C Application Guide for information on zeroing the RF Power
meter.
Error −1312 Data from RVC contains invalid bits in word [1,2,3].
Indicates that the decoded data received on the reverse voice channel contains invalid bits
in word 1 and/or word 2 and/or word 3. The raw decoded data is displayed in hexadecimal
format in the
top right-hand portion of the CALL CONTROL screen. Raw decoded
data is only displayed when the
CALL CONTROL screen Display field is set to
Data.
Error −1313 Timeout occurred while in Maintenance state.
Indicates that the simulated Base Station’s internal timer expired before the mobile station
was taken out of the maintenance state. The internal timer is set to 20 seconds when the
maintenance order is sent to the mobile station.
Error −1314 Alert attempted while not in Maintenance or Connect state.
Indicates that an attempt was made to send an Alert order to the mobile station when the
Call Processing Subsystem was not in the Maintenance state or Active state.
