Probably ISDN or DACS, but as you have had ADSL working already it seems a bit odd.
Did the upgrade to FTTC happen on the 22nd as planned?
Hi - Yes I'm on faster fibre as of the 22nd. I don't think I've been on the site since I upgraded to FTTC. It wasn't on there last time I looked & that was probably a couple of weeks back..
@MattS - This is still showing on the DSL Checker. It's now a good 3 months since you said you would contact OR to have it removed..
It's not a problem now but might be in the future should I choose to move away from BT. Thanks..
