Programming The CALL CONTROL Screen
Display
The top right-hand portion of the CALL CONTROL screen is used to display:
• Decoded data messages received from the mobile station on the reverse control channel
or the reverse voice channel. If a decoding error occurs the raw data message bits
received from the mobile station are displayed in hexadecimal format.
• Modulation quality measurements made on the mobile station’s RF carrier while on a
voice channel.
The Display field is used to select the type of mobile station information to be
displayed.
The :MODE command is used to control the
Display field for AMPS, TACS,
and JTACS system types.
The query form of the command (that is, :MODE?) can be used to determine the
current setting of the
Display field while AMPS, TACS, and JTACS system
type is selected.
Syntax
:MODE <’><DATA/MEAS><’>
:MODE?
Example
OUTPUT 714;"CALLP:MODE ’DATA’"
OUTPUT 714;"CALLP:MODE?"
ENTER 714;Screen$
Setting the Display field to Data
When the Display field is set to Data the top right-hand portion of the CALL
CONTROL
screen is used to display decoded data message(s) received from the
mobile station on the reverse control channel or the reverse voice channel.
If the data message(s) received from the mobile station can be correctly decoded,
the decoded message contents are displayed.
Figure 34, "The CALL CONTROL
Screen," on page 460
shows an example of a correctly decoded reverse control
channel data message being displayed in the top right-hand portion of the screen.
If the data message(s) cannot be correctly decoded, the raw data message bits are
displayed in hexadecimal format.
Figure 33, "CALL CONTROL Screen with
Decoding Error Message Display," on page 455
shows an example of the raw data
message bits being displayed in hexadecimal format in the top right-hand portion
of the screen when a decoding error has occurred
