Chapter 8, Programming the Call Processing Subsystem
Programming the CALL BIT Screen
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
SAT: field on the CALL CONTROL screen.
When using the CALL BIT screen the user is responsible for setting the contents
of all messages used in a messaging protocol. When using the CALL BIT screen
the Call Processing Subsystem host firmware sends the correct message(s) at the
correct time(s) as defined in the applicable industry standard. Message content is
the responsibility of the user.
Using the CALL BIT screen requires expert knowledge of the call processing
messaging protocols used in the selected system (that is, the system selected in the
System Type field on the CALL CONTROL screen).
The contents of eleven different messages can be modified from this screen. The
message to be modified is selected using the
Set Message field. The eleven
messages whose contents can be modified are:
• Forward Control Channel Messages for Paging, Origination, Order Confirmation, and
orders.
• “SPC WORD1 Message Fields” on page 487
• “SPC WORD2 Message Fields” on page 489
• “ACCESS Message Fields” on page 492
