Advanced Communication Function/Network Control Program
ACF/NCP

   <networking> (ACF/NCP, usually called just "NCP") The primary
   {SNA} {network 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}.
