Chapter 6, Call Processing Subsystem
Using the CALL CONTROL Screen to Test Call Processing Functions
2. Couple the variable-frequency notch filter to AFGen1.
This step is only required if audio testing is to be done on the mobile station. This step
couples the variable-frequency notch filter to the output frequency of AFGen1 (audio
frequency generator1). The notch filter is used when making SINAD measurements.
AFGen1 is used to generate the audio tone for the SINAD measurement. Coupling the
notch filter to the audio source ensures the most accurate measurement.
a. Press and release the blue SHIFT key and then the DUPLEX key to display the
CONFIGURE screen.
b. Position the cursor on the Notch Coupl field and select AFGen1.
Configure the Test Set
Select CALL CNTL from the To Screen menu. The CALL CONTROL screen will be
displayed.
3. Verify that the Test Set configuration information is appropriate for the mobile station
to be tested. Check the following fields:
a. System Type - Select the type of cellular system to be simulated (AMPS,
NAMPS, TACS, JTACS, DAMPS, DCCH).
If the System Type field was modified in step3. a. the control channel will become
active since modifying this field automatically activates the control channel. Refer to the
System Type field description, on page 136.
b. Cntl Channel - Set the control channel number to be used by the Test Set.
NOTE: If the Cntl Channel field was modified in step 3.b. the control channel will become active
since modifying this field automatically activates the control channel. Refer to the Cntl
Channel field description, on page 126.
c. Amplitude - Set the output power of the Test Set’s transmitter (that is, the output
power of the Test Set’s RF Generator).
d. SID - Enter the system identification number of the Test Set as a decimal number.
e. Chan: (right-hand field) - Enter the voice channel number which will be assigned
to the mobile station by the Test Set as either an initial voice channel assignment or
as a handoff voice channel assignment.
f. Ch Loc: (right-hand field, NAMPS system type only) - Select the narrow analog
channel location which will be assigned to the mobile station by the Test Set as ei-
ther an initial channel location assignment or as a handoff channel location assign-
ment. The choices are Lower (10 kHz below standard wide analog channels),
Middle (centered at the wide analog channel), Upper (10 kHz above the standard
analog channel) or Wide Chan.
