Model 458-LM-HD ADSL2+ Local Loop Simulator

Model 458-LM-HD ADSL2+ Local Loop Simulator

Model 458-LM-HD ADSL2+ Local Loop Simulator accurately reflects the attenuation and impedance of 26 AWG PIC as specified in the ANSI T1.417 standard. The 458-LM-HD conveniently plugs into the 458 Series (16-Slot) and 458-3SLB (3-Slot) chassis for easy control of loop length and offers eight channels per line module. Channel 1 offers hi-resolution programming of loop lengths from 0-31,750 ft in 250-ft increments while all channels may be programmed from 0 – 30,000 feet in 2,000-ft increments.

Main Features
  • Simulates 26 AWG PIC as specified in ANSI T1.417
  • Bandwidth to 4.5 MHz
  • 8 channels per line module
  • Channel 1: loop lengths programmable from 0 to 31,750 ft in 250-ft increments
    Channel 2 – 8: loop lengths programmable from 0 to 30,000 ft in 2,000-ft increments
  • Plugs into our Model 458-CC-16 (16-slot) or 458-3SLB (3-slot) chassis
  • Channel-to-channel isolation up to 90dB
  • Ability to open loop at either end of any channel
