phone line has no dial tone

[markythesparky]

went to use my phone yesterday and found i had no dialing tone,so removed the front plate off the openreach 5c mk 4 socket and plugged in the phone to the test socket and it works fine, so i suspected the extension line so i removed the extension cables from the openreach socket and re fitted the front and i still did not have a dialing tone so i unplugged the cable to the modem and still no dialing tone , so proving the extesion cable is not at fault, do the fronts of the openreach boxes fail, i have plugged an old filter in and broadband and phone work fine  before i contact BT I was wondering if this is a known fault with these boxes.

The 5c can be a bit iffy with not making good contact. Make sure the front plate is firmly clipped in place. I would unplug the hub completely whilst attempting to get the faceplate to make a good connection and restore dial tone or DLM might take action with the multiple disconnects.

can the connection just drop after 12months of not  being touched

Faults have to happen some time

A basic master socket consumer panel ,is pretty much just a male/female plug and socket so any defect is likely to be a ‘contact’ issue between the plug and socket contacts , ‘interstitial’ faceplates that effectively remove the need for a separate ADSL filter , have electronic components that can and do fail.

Most likely a high resistance connection caused by oxidisation of the connecting surfaces. You could try a spray contact cleaner  like Servisol Super 10, its usually very effective. Its also good for removing sticky residues.
