DACS - Computer Definition
Synonymous with digital cross-connect system (DCCS or DXC). A non-blocking, electronic common control (ECC) switch that serves to cross-connect digital carrier bit streams on a buffered basis by redirecting individual channels or frames from one circuit to another through an electronic cross-connect matrix. A DACS is much like a static switch in that connections can be changed to alter physical paths, on a semi-permanent basis, rather than a call-by-call or packetby-packet basis. A DACS is akin to a digital, electronic version of a manual distribution frame, which can take the form of a main distribution frame (MDF) or intermediate distribution frame (IDF). See also ECC, IDF, MDF, non-blocking, and switch.
