Overview
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...
