  • Description

    256-kbps Line Driver (LDM-MR128), Standalone, V.35, 115-VAC


    Quick Facts

  • Supporting half- or full-duplex, this standalone V.35 line driver minimizes line distortion for reliable 256-kbps data communications.
  • Selectable speeds range up to 256 kbps.
  • Built-in BERT supports V.54 loop diagnostics.

  • Further Details

    With this line driver operating at 256 kbps, you can drive data up to 3 miles (4.8 km). And you get even longer distances at slower speeds.

    Use it in full- or half-duplex applications. Run loopback tests right from the front panel or from the interface’s control signals.

    This line driver also eliminates normal line distortion to ensure clean transmissions every time. Thanks to conditioned diphase modulation, you’ll get immunity from background noise for more efficient data transmission and reception.
