(Subscriber Line Interface Circuit) is a bipolar integrated circuit in 90 V technology which replaces the conventional transformer based analog line interface and ringrelay in FITL, WLL, ISDN-TA and other telecommunications equipment with a modern, compact solid state design. Not only is required PCB area reduced, but less component weight and height result as well. The PBL 387 10/1 has been optimized for low cost and to require only a minimum of external components. The PBL 387 10/1 constant-current feed system, programmable to max 40 mA of line current, can operate with battery supply voltages down to -21 V to reduce lin
