as for the operation in battery boosted, a positive

card.As the rightringing signalamplification bothin

DESCRIPTION

The ST SLIC KIT (L3000S/L3030)is a set of solid

statedevicesdesignedto integratemain of the fun-

ctions needed to interface a telephoneline. It con-

sists of 2 integrated devices : the L3000S line

interfacecircuit and the L3030control unit.

Thiskit performsthe main featuresof the BORSHT

functions:

Thiskit is fabricatedusing a 140VBipolartechnolo-

gy for L3000Sand a 12VBipolar I²L technologyfor

L3030.

L3030 is available PLCC44 and L3000S in both

FLEXIWATT15andPowerSO-20forsurfacemount

application.

This kit is suitable for all the following applications:

C.O.(CentralOffice),DLC(DigitalLoopCarrier)and

high range PABX (Private Automatic Branch Ex-

change).
