Advanced Communication Function/Network Control Program
(ACF/NCP, usually called just "NCP") The primary SNAnetwork 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.
