The ME1001 is a Long Line Simulator from Mountain Engineering. The ME­1001 Line Simulator is a highly accurate, programmable filter designed to simulate the attenuation versus frequency characteristics of the #22AWG (0.7mm) unshielded twisted­pair transmission wire commonly used in long distance telephone trunk lines in the US and around the world. The same wire is also found in office buildings and industrial complexes where it forms the backbone of PBX and LAN communication systems.
