The wire line simulator product family ideal for testing high speed modems.

A complete family of local loop wire-line simulators ranging from ADSL, HDSL, T1, E1 and VDSL for compact laboratory or field instrumentation testing or for production line testing of high speed modem devices. Units emulate wire transmission lines and can be incremented in sections ranging from 500 ft. on up to 26 thousand feet, including Bridge Tap connections.

Also included in the family is a loop interference simulator that generates shaped narrow band and broad band noise for testing local loop transmission products such as ISDN, HDSL, T1 and ADSL modems.
