BT phone home....

Connection drops when incoming calls (phone rings) occur, even without a phone connected (just the modem with/without filter). Outgoing calls can sometimes do it. QLT is ok (some white noise) when only the phone is plugged in. Can hear lots of crackle/noise/bleeps/whirrs when modem is (un)syncing with exchange. Tried many modems and filters, no difference. Entire D-side has been pair swapped. New NTE5c socket. Socket wires pair swapped. BT66 to DP chamber pair swapped. None of it has made any difference.

It's always the upload sync that ends up down at 192Kb/s or under. Seen it as low as 32Kb/s. Have to keep ringing the line from a mobile regularly (several times a day) to eventually get it to sync at a normal rate, with a normal u/l SNR. It's like playing broadband keepy uppy!

Could be a fault on the MDF in the exchange, as that is where the phone and broadband join together. Perhaps an unsoldered connection?

There are quite a number of connections at that point, and many older exchanges still have soldered connection blocks, and not IDC connections.

You need to request a quality check by an Openreach Frames Technician.

Upload speed will always be most affected by bad connections.

Thanks Keith. I have been suspecting the exchange equipment for some time. The ADSL had been moved back to OR kit some time ago but the POTS has always been on BT.

Will that require another OR home visit? I'm amazed and dismayed at the level of customer involvement, instead of OR fixing everything they have access to 24/7/365.

It needs an exchange visit. An SFI (Special Fault Investigation), if they still exist.

As this has been going on for a while now, I will ask a moderator to help.
