FLEXIWATT15
The ST SLIC KIT (L3000N/L3030)is a set of solid
statedevicesdesigned to integratemain ofthefun-
ctionsneeded to interface a telephone line. It con-
sists of 2 integrated devices : the L3000N line
interfacecircuit and the L3030 controlunit.
This kitperforms themain featuresof theBORSHT
functions:
-
Battery feed
-
Ringing
-
Signalling
-
Hybrid
Additionalfunctions,such asbatteryreversal,extra
batteryuse, line overvoltagesensingandmetering-
pulse injection are also featured ; most external
characteristics,asACandDCimpedances,arepro-
grammablewith externalcomponents.TheSLICin-
jects ringing in balancedmode and for that,as well
as for the operation in battery boosted, a positive
batteryvoltageshallbe availableon the subscriber
card.As theright ringing signalamplificationbothin
voltageand in current is provided by SLIC,the ring
signalgeneratorshall onlyprovidealowlevel signal
(0.285Vrms).
Thiskit is fabricatedusing a 140VBipolartechnolo-
gy for L3000Nand a12V Bipolar I

Ltechnologyfor
L3030.
L3030 is available PLCC44 and L3000N in both
FLEXIWATT15andPowerSO-20forsurfacemount
application.
This kit is suitable forall the following applications:
C.O.(CentralOffice),DLC(DigitalLoopCarrier)and
high range PABX (Private Automatic Branch Ex-
change).
