* You use the same telephone line to your house as the ADSLx connection
* The engineer rings you up and says he/she are about to change the line to fibre
* Your voice line / BB goes off
* About 10-20 mins later...
* The engineer comes into your house and changes the master socket to a new filtered version. Sometimes they add an extension (if you ordered it) to move the connected socket to another location (up to 20-30M max).
* A test is done on line quality with a special meter he/she has.
* The engineer then connects the BT FTTC modem that they bring
* He/She/You connect the new Router from your ISP. This should have been pre-delivered from your ISP.
* The line starts and your ISP's router connects up. Sometimes this needs user/password to be set on your ISP's Router.
* Connect your PC etc and all is working
Takes about 30mins to 1hr max
For most people (not all) it is smiles all round...
