Description
The Zarlink ZL49200 Dual SLIC hybrid provides an
interface between a switching system and a subscriber
loop with 600 Ω impedance. The functions provided by
each SLIC include battery feed, 2 W to 4 W
conversion, off-hook and dial pulse detection. All driver
electronics are included on the hybrid in order to
minimize the number of external components required
by the user.
