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 loo...
