Abstract (en)
[origin: WO8301162A1] A subscriber loop interface circuit (SLIC)(10) is used in a terminator circuit (100) which is ground referenced for providing signal conversion between a two-wire bidirectional transmission signal path (102, 104) and a pair of two-wire unidirectional transmission signal paths (106, 108). The SLIC and associated circuitry allows the use of an all electronic circuit to replace bulky transformers generally utilized in telecommunication systems.
