Introducing our ADSL2++ Local Loop Simulator Line Module for North America. The Model 458-LM-HD 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.
