A - 8 ONline 10BASE-T Security Module Installation and Operation Guide
Some installations may have 50-pin Telco connectors at the wiring closet.
We recommend using a patch panel that converts from 50-pin to RJ45-type
connectors. This allows direct connection to the Security Module in your
ONline System Concentrator.
Twisted Pair Cables
The cables that are supported must meet the following qualifications:
Level 3 or higher
22 or 24 gauge twisted pair cable
85 to 115 ohm impedance
minimum of 2 pairs
A pair is usually a solid color wire twisted with a striped wire with the same
color.
