Preliminary February 2000 PBL 386 61/2 Subscriber Line Interface Circuit Description The PBL 386 61/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in Central Office, MUX and other telecommunications equipment.
The PBL 386 61/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications.
The PBL 386 61/2 emulates a transformer equivalent dc-feed, programmable between 2x25 Ω and 2x900 Ω, with short loop current limiting adjustable to max 65 mA.
A second lower battery voltage may be connected to the device to reduce short loop power dissipation.
The SLIC automatically switches between the two battery ...
