The ST SLIC KIT (L3000S/L3030)is a set of solid-state devices designed to integrate most 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. This kit performs the main featuresof the BORSHT
Functions:
Additional functions, such as battery reversal, extra battery use, line overvoltage sensing, and metering pulse injection, are also featured; most external characteristics, such 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 boost mode, 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 generator shall only provide a low-level signal (0.285Vrms). This kit is fabricated using a 140V Bipolar technology for L3000S and a 12V Bipolar I2 L technology for 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 Exchange).
