The CALL BIT screen is designed to give an advanced user the capability to modify the
contents of the forward control channel and forward voice channel signaling messages
that are used in all processing messaging protocol.
A messaging protocol is defined as the sequence of messages sent from the Test
Set to the mobile station to perform a desired action, such as registering a mobile
station. Modifying the contents of one or more messages may be required for
testing the robustness of a mobile station's call processing algorithms or for new
product development.
Using the CALL BIT Screen
Using the CALL BIT screen requires expert knowledge of the call processing
messaging protocols used in the system selected in the
CALL CONTROL screen.
The CALL BIT screen should not be used to change any parameter that can be set
on any other Call Processing Subsystem screen. The contents of the applicable
fields on the CALL CONTROL screen and the CALL CONFIGURE screen are
not updated to reflect any changes made while using the CALL BIT screen. There
is no coupling between the CALL BIT screen and the Test Set.
For example: changing the value of the SAT color code field (SCC) in the forward
control channel mobile station control message (MS IntVCh) does not change the
setting of the field on the CALL CONTROL screen.
