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.
