product overview

The Model 700 Series products are multi-standard/multi-channel local loop simulators and are the ideal solution for ADSL, ADSL2, ADSL2+, and VDSL2 chip/modem/DSLAM testing. The highly accurate models in this series are offered in several different configurations, including combinations of wire types, in 8, 12 or 16-channels.

The 700 Series models offer fine granularity and long line lengths. They may be ordered with or without the ability to inject variable AWGN on the CO and/or CPE side of each loop.
