Cat5e 25 pair cable is used for multiple cable
runs using a 25 Pair connector to hook up. Cat5e is rated higher then
the 16MHz cable that you will find with just Telco cable.
Cat5e 25 pair cable is the choice. When you want to connect this
cable on either end then you will want a 25 pair 110 punch down block or 100 pair one.
You can also use the Telco patch panel with
RJ21X terminations in the rear. This cable is used for both voice and data. The 110 block should
be Cat5e rated or if your just running voice it can be a 66 block style. But if you
run the 110 block then you can hook data or voice without much more effort.
