BORSCHT is an acronym for the set of functions performed by a subscriber line interface circuit (SLIC) in the line card of a telecommunication system providing plain old telephone service. The letters represent the following functions: battery feed (B), overvoltage protection (O), ringing (R), signaling (S), coding (C), hybrid (H), and test (T).[1]
An earlier or alternate version of the acronym is BORSHT, lacking the letter C for the coding function.[2]
