Indoor/Outdoor Multi-Line NID

Corning NI-3000 series multiline network interface devices (NIDs) combines Corning universal line modules (ULMs) in enclosures suitable for indoor and outdoor mounting. Available in 25- or 50-line capacity, the housing is made of weather-resistant powder-coated aluminum ideal for indoor or outdoor use. The NI-3000 series multiline NIDs come equipped with Corning IDC universal line module (ULM) and integrated hybrid IDC universal station protector (USP), combining overvoltage protection, environmentally sealed insulation displacement connections (IDCs), subscriber bridge and RJ-11 test jack in one compact unit. The ULM has an innovative bypass switch design that physically disengages the plug from the jack prior to subscriber wiring access, fulfilling UL safety requirements. Highly visible orange levers and engraved line module doors clearly indicate each tip/ring slot, as well as connected and disconnected IDC positions.
