(1) (Service Control Point) A node in an SS7 telephone network that provides an interface to databases, which may reside within the SCP computer or in other computers. The SCP may also be combined with the SS7 node that routes messages, called a "signal transfer point" (STP).

The local exchange node, which is called the "service switching point" (SSP) sends SS7 messages to SCPs to retrieve subscriber and routing information. The databases support such features as 800 and 900 numbers, calling card validation, collect and third-party billing calls. Databases for cellular providers hold subscriber information as well as visitor information (other carriers' customers moving through at this moment). See SS7, SSP and AIN.

(2) (Secure Copy Protocol) A secure version of the Unix remote copy (rcp) command. See SSH.
