Chapter 8, Programming the Call Processing Subsystem

The Call Processing Subsystem programming commands and command syntax 
are detailed in 

. Refer to the “Programming the 

(screen name) Screen” sections in this chapter for detailed information on using 
the Call Processing Subsystem programming commands for each screen.

The *OPC, *OPC? and *WAI commands should not be used for determining if a Call

Processing Subsystem state command has completed successfully. Call Processing
Subsystem states do not complete, a state is either active or not active. Using the *OPC,
*OPC? or *WAI commands with a Call Processing Subsystem state command results in a
deadlock condition. Refer to the *OPC, *OPC? and *WAI commands in section 

 for descriptions of the deadlock conditions.

The *OPC, *OPC? or *WAI commands should not be used with any of the following Call
Processing Subsystem commands: :ACTive, :REGister, :PAGE, :HANDoff, :RELease.

The Call Processing Subsystem Status Register Group should be used to control
program flow. Refer to 

 for further information.
