If an error message appears
If an error message appears
Bad TCH number
This means that an invalid traffic channel number has been entered in
the parameter list. Valid traffic channel numbers are 1 through 124 for
GSM900, 512 through 885 for DCS1800, and 512 through 810 for
PCS1900. Check parameters RT Default Traffic Channel and RT
TCH.
BET trigger not found
This means a bit error test would not run. Some possible causes are:
• The RF link was dropped before the bit error test started.
• The RF level from the HP/Agilent 8922 is too low.
Connection Failure
This means the RF link between the mobile station and HP/Agilent
8922 was dropped. If the Mobile Station is operating correctly, check
parameters AE IMSI (there are two).
Error in parameter “CP control channel type”
An invalid control channel type was entered in the parameter list. Valid
field entries are 0 and 1. Check parameter CP Control Chan Type.
Error in power class number
This means the mobile station has returned an incorrect power class
number. The allowable power class numbers are 1 through 5 for
GSM900 and 1 or 2 for DCS1800.
Error in TCH handover
An invalid number was entered for the TCH handover parameter. Valid
field entries are 0 and 1. Check parameter RT Cell TCH H.O.
Improper context terminator or filename is undefined
This could mean the software has not been loaded. Run a pre-defined
test procedure to make sure the software is loaded into the HP/Agilent
8922.
