Overview
Preliminary Information February 2000 PBL 386 14/1 Subscriber Line Interface Circuit Description The PBL 386 14/1 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in ISDN Network Terminal Adapters and other short loop telecommunication equipment which often are remote powered, and by that, the available power is limited.
The PBL 386 14/1 has been optimized for low total line interface cost, low power and requires a minimum of external components.
The PBL 386 14/1 has constant current feed, programmable to max 30mA.
The SLIC uses a first battery voltage for On-hook .
A second battery voltage is used for Off-hook and must be connected, to reduce short loop power dissipation.
The SLIC automatically switches between the two battery supply voltages without need for external components or external control.
The loop current controls the switching between On-hook and Off-hook battery.
The SLIC incorporates loop current, ground key and ring trip detection ...
