It consists of 2 integrated devices : the L3000S line interface circuit and the L3030 control unit. This kit performs the main 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 right ringing signal amplification both in voltage and in current is provided by SLIC, the ring signal generatorshall onlyprovide a low level signal (0.285Vrms). This kit is fabricatedusing a 140V Bipolar technology for L3000Sand a 12V Bipolar I2L 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 Exchange). 1/29 L3000S - L3030 PIN CONNECTIONS (top view) PLCC44 FLEXIWATT15 VBN.C.

Positive Supply Voltage Monitor Positive Battery Supply Voltage Battery ground relative to the VB+ and the VB– supply voltages. It is also the reference ground for TIP and RING signals. Positive Power Supply + 5V 2 wire unbalanced voltage input. Output voltage without current capability, with the following functions : - give an image of the total battery voltage scaled by 40 to the low voltage part. - filter by an external capacitor the noise on VB–. Negative Battery Supply Voltage Analog Ground. All input signals and the VDD supply voltage must be referred to this pin. Voltage reference output with very low temperature coefficient. The connected resistor sets internal circuit bias current. Digital signal input (3 levels) that defines device status with pin 12. Digital signal input (3 levels) that defines device status with pin 11. High precision scaled transversal line current signal. Ia + Ib IT = 100 Scaled longitudinal line current signal.
