The Mountain Engineering ME-1002 is a Short Line Simulator. The ME-1002 simulates three types of transmission line commonly used in short distance, interoffice digital telephone systems: 100Wand 120Wtwisted-pair and 75Wcoaxial cable. It simulates the frequency dependent attenuation characteristics of these lines at the lengths recommended for output pulse mask testing by both US and European standards committees. Receiver input sensitivity can also be tested through the RJ-48 connector with simulated line loss ranging from 0dB to 18dB. The ME-1002 also simulates 0m to over 1200m of 75Wcoaxial cable. All line length settings are addressable in units of Feet, Meters, and dB of Attenuation at both 1.544Mb/s and 2.048Mb/s data rates.
