DESCRIPTION

PLCC44

FLEXIWATT15

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

state devices designed to integrate main of the fun-

ctions needed to interface a telephone line. It con-

sists of 2 integrated devices : the L3000S line

interface circuit and the L3030 control unit.

This kit performs the main features of the BORSHT

functions :

- Battery feed

- Ringing

- Signalling

- Hybrid

Additional functions, such as battery reversal, extra

batteryuse, line overvoltagesensing and metering-

pulse injection are also featured ; most external

characteristics,as AC and DC impedances,are pro-

grammable with external components.The SLIC in-

jects ringing in balanced mode and for that, as well

as for the operation in battery boosted, a positive

battery voltage shall be available on the subscriber

card. As the right ringing signal amplification both in

voltage and in current is provided by SLIC, the ring

signal generatorshall only provide a low level signal

(0.285Vrms).

This kit is fabricated using a 140V Bipolar technolo-

gy for L3000S and a 12V Bipolar I

2L technologyfor

L3030.

L3030 is available PLCC44 and L3000S in both

FLEXIWATT15 and PowerSO-20 for surfacemount

application.

This kit is suitable for all the following applications:

C.O. (CentralOffice),DLC (Digital LoopCarrier) and

high range PABX (Private Automatic Branch Ex-

change).
