Cat3 RJ11 Modular Jack



When discussing voice cable, different applications and cable grades can come into play. With the advent of Voice over Internet Protocol (VoIP) the future of telephone cabling may change dramatically. But the fact of the matter is, we are still seeing over 90% of companies wiring for voice the same way it's been done for the last 20 years: using voice grade wire and standard RJ11 jacks at the user end. In the wiring closet, the terminations of choice are still 66 blocks, 110 style terminal blocks (developed by AT&T), Bix blocks and Krone fields.

These configurations give companies, and the majority of phone vendors, all the flexibility they need at a very reasonable cost. When voice cable is being installed in conjunction with your network cabling, the labor cost is greatly reduced. The cost of Category 3 cable, whether plenum rated or non-plenum, is very reasonable in relation to Category 5, and the jacks, usually 6 conductor USOC, are inexpensive. We generally split the 4 pair voice cable at the user end, and install 2 RJ11 jacks. This is possible because the large majority of phone systems on the market today require only 1 pair of wires, some others require 2 pairs. This gives our customers the option and flexibility to install any combination of phones, modems and analog lines at any location.
