#### Details

Trunk control programs perform all signaling tasks necessary to interface with the telephony protocol used on the line or trunk. TCPs are loaded onto an NMS board during initialization. After a TCP is loaded, applications must start the protocol before they can use the TCP to perform call control on specific ports.

For more information about starting protocols on NMS boards, refer to the ADI Service Developer's Reference Manual. For more information about loading and running TCP files, refer to the NMS CAS for Natural Call Control Developer's Manual or to the NMS ISDN for Natural Call Control Developer's Manual.

Note: The TCPFiles[x] keyword is required for configurations that run CAS signaling protocols.
