How to change an old 2/1a BT master socket to a new style NTE5 master socket

Hi, this video shows you how to change a very old BT 2/1a master socket into a newer NTE5a master socket so you can then test your line using the test socket to prove telephone and broadband faults and also attach on Iplates, ADSL faceplates or the new VDSL Fibre faceplates.
Many thanks Vince
