L3030 - SUBSCRIBER LINE INTERFACE KIT

Description

The ST SLIC KIT (L3000S/L3030) is a set of solid state devices designed to integratemain of the functions needed to interface a telephone line.

It consists of 2 integrated devices : the L3000S line interface circuit and the L3030 control unit.

Features

  • of the BORSHT functions : feed - Battery - Ringing - Signalling - Hybrid June 1997 Additional functions, such as battery reversal, extra batteryuse, line overvoltagesensing and meteringpulse injection are also featured ; most external characteristics,as AC and DC impedances,are programmable with external components. The SLIC injects 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.
