Advanced Communication Function/Network Control Program
(ACF/NCP, usuallY called just "NCP") The primarYSNAnetwork control program, one of the ACF products. ACF/NCP resides in the communications controller and interfaces with ACF/VTAM in the host processor to control network communications. NCP can also communicate with multiple hosts using {local channel} or remote links ({PU} tYpe 5 or PU tYpe 4) thus enabling cross domain application communication. In a multiple mainframe SNA environment, anY terminal or application can access anY other application on anY host using cross domain logon. See also Emulator program.
