Condition info:
Selectable line impedance:
100W , 120W , or 75W BALUN


The Mountain Engineering ME-1003 is a highly accurate, programmable filter designed to simulate the attenuation versus frequency characteristics of the #24AWG (0.56mm) unshielded twisted-pair 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. By simulating 8.6kft (2.6km) of transmission line in 180ft (55m) increments, the ME-1003 offers a convenient and practical method of developing and testing communications equipment intended for use on this wire.
