IDC Line Modules

The Corning universal line module (ULM) is a sealed, tool-less subscriber bridge compatible with all industry-standard network interface devices (NIDs). The modular design allows the protector to separate itself from the subscriber module for mounting inside any NID application. Combining environmentally sealed insulation displacement connections (IDCs) with the integrated protector enables maximum, heavy-duty protection and termination in one compact, modular unit.

An innovative bypass switch design 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. Technicians simply plug standard test clips into each tip/ring contact for quick verification and integrated test ports facilitate craft maintenance and troubleshooting for both telco and customer networks. With 4-line capacity, line test electronics, RJ-11 test jack and integrated test ports, the ULM exceeds Telcordia requirements for sealed terminations.

The ULM design minimizes installation time and wiring errors, providing significant operational savings. Tool-less, gel-sealed IDC terminals simplify field wiring connections as insulated wires are no longer required to be stripped and screw-terminated. A snap-in ground feature easily accommodates additional line module expansions and factory-controlled, preterminated tip/ring connections between line module and protector unit improve installation accuracy. The universality of the ULM simplifies purchasing and inventory management by reducing the number of part numbers and standardizing on one common platform.
