Device Overview

Summary

The Le79Q2281 Quad Intelligent Subscriber Line Audio Processing Circuit (ISLAC), in combination with VE790 Series SLIC devices, implements four-channel universal telephone line interface. The Le79Q2281 Quad ISLAC device has integrated self-test and line-test capabilities to resolve faults to the line or line circuit. The integrated test capabilities are crucial for remote applications where dedicated test hardware is not cost effective.

Additional Features
  • High performance digital signal processor provides programmable control of all major line card functions
    • A-law/µ-law and linear codec/filter
    • DC loop feeding
    • Internal ringing generation and integrated ring-trip detection
    • Adaptive hybrid balance
    • Line and circuit testing - Meets GR-909 and GR-844 test requirements
    • Tone generation (DTMF, FSK, random noise, and arbitrary tone)
    • Metering generation at 12 kHz and 16 kHz
    • Modem Tone Detection
  • Selectable PCM/MPI or GCI digital interfaces
    • Supports most available master clock frequencies from 512 kHz to 8.192 MHz
  • General purpose I/O pins
  • +3.3 V DC operation
  • Exceeds LSSGR and ITU requirements
  • Supports external ringing with on-chip ring-trip circuit
    • Automatic or manual ring-trip modes
  • Supports CallerNumber Identification (CID) tone generation
