    product overview

    Introducing our ADSL2+ Local Loop Simulator Line Module for Europe. The Model 458-LM-HDE accurately reflects the attenuation and impedance of 0.4 mm PE as specified in ETSI TS 101 388. The 458-LM-HDE 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 0-9,450 m in 150-m increments while all channels 2 - 8 may be programmed from 0 - 9,000 m in 600-m increments.
