IDC (Insulation Displacing Connectors) termination is the preferred method for terminating wires for voice or data connectivity; such as 66 blocks and 110 systems.
Cablesys insists on IDC termination for connecting Telco connectors to a 25-pair cable because the connections have excellent performance and high reliability. The terminals have spring properties that hold the wires in a stable mechanical condition.
Manual soldering can be inconsistent and subject to failure as a result of mechanical or temperature stresses. The bottom line is that Cablesys Telco Cables perform better and cost 20% less.
