BORSCHT is an acronym for:

The electronic functions collectively known as BORSCHT are used in Plain Old Telephone Service (POTS) telephony signaling, line supervision and telephone terminal operation. BORSCHT circuitry is typically located on a telecommunications network line card and is increasingly integrated into a chipset by several semiconductor companies for low-cost implementation of a standard POTS telephone interface for non-traditional telephony networks such as cable television networks, fiber optic, VoIP and wireless local loop.
