KRONE EQUIPMENT | |||||||
BT decided to use an Insulation Displacement Connections IDC
system, produced by Krone,
on all their voice terminations in the field. It was because of BT's buying power and the fact
that BT commanded a such a presence in the business that other British companies adopted Krone as standard equipment.
Overview of the Krone Voice cabling IDC system Each slot on an IDC connector can take two wires with a conductor sizes of 0.4mm to 0.65mm. The principle of connection is that the wires are pushed into the IDC connector with an Inserters Wire No. 2A. The inserter will push the wire home and then cut the free end of the wire off. The inserter also has a fold out hook which is used to remove terminated wires. This hook should always be folded back into the handle when not in use.
