June 1999 PBL 386 50/2 Subscriber Line Interface Circuit Description The PBL 386 50/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in Central Office Metering applications and other telecommunications equipment. The PBL 386 50/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications. The PBL 386 50/2 emulates resistive loop feed, programmable between 2x50 Ω and 2x900 Ω, with short loop current limiting adjustable to max 45 mA. In the current limited region the loop feed is nearly constant current with a slight slope corresponding to 2x30kΩ. A second, lower battery voltage may be connected to the device to reduce short loop power dissipation.
