No ADSL2 at the exchange. I went for BT Business because they *assured* me that it would increase the uplink speed available to the line.
I assume this means that they reprogram the part of the DSLAM that my local drop is connected to, to allow it to negotiate up to 832kbps. (I thought they had said the downllink rate increases to 8000kbps but not too concerned about the download rate)
I had found out previously on this forum that on consumer broadband services the max uplink is 448, and sure enough my modem is telling me that I am "connected at 448kbps". Now of course I never get this in reality, the online speed testers tell me anything from 180k to 300k depending on time of day.
but the fact that the modem tells me "connected at 448k" made me think that this is the result of the handshaking that the modem does with the exchange, and its basically a text message from the DSLAM telling me what sort of connection I am actually paying for.
in migrating to business broadband, a local openreach tech advised me that some unseen department would dial in to the DSLAM and tweak it so that my little part of it would change to a business connection. Now Im not expecting anything amazing but I was expecting the connection information at the modem to change.
I spoke to 3 different UK operators on the "business broadband" team at BT and they all assured me that the uplink would increase. I made sure they knew exactly where I was and what my local excchange was.
Im afraid I wont be surprised to find out that they were all wrong, and in fact our local excchange can only do max uplinks of 448.
how do you know if you have ADSL2+ at the exchange?
our dslam looks like this
. Is it ADSL2?
