Programming the CALL CONFIGURE Screen
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
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 433 for information on zeroing the RF Power meter manually.
Refer to “Using the Analog Call Processi ng Subsystem” in the Application Guide
for operating information on the use of the CALL CONFIGURE screen.
Refer to Chapter 6, “Call Processing Subsystem” , in the HP 8920 User’s Guide
for detailed information on the operation and manual use of the CALL
CONFIGURE screen.
The information presented in this section covers the CALL CONFIGURE screen
programming commands and how to use them.
CMAX
The CMAX field sets the number of access channels in the system. This will
determine how many channels must be scanned by the mobile station when trying
to access the Test Set. The value of this field will affect the time required for the
mobile station to connect with the Test Set.
The :CMAXimum command is used to control this field.
The CMAX field is an immediate action field. That is, whenev er the :CMAXimum
command is sent, the change is reflected immediately in the appropriate signaling
message(s) being sent on the forward control channel. No change occurs to the
current state (i.e. Active, Register, Page, Access, Connect) of the Call Processing
Subsystem.
The query form of the command (that is, :CMAXimum?) can be used to
determine the current control channel setting.
Syntax
:CMAXimum <integer number>
:CMAXimum?
Example
OUTPUT 714;"CALLP:CMAX 21"
OUTPUT 714;"CALLP:CMAX?"
