Forgive me if this is a dumb question but I've looked around for a basic guide to how DLM operates and can't find one so...
I understand that DLM reacts to errors and adjusts speed accordingly to gain a stable line but I'm trying to get a better understanding of how DLM gets the information (and where it sends it to make changes). Is it correct that it's just the modem itself that measures the errors and sends this info back up the line to some point (to the cabinet or the exchange or further)?
Also does anything downstream from the modem (ie the router, the ethernet cabling, the wifi, the connected PC) get measured? If so would that include the type of traffic passing through? For example if you're trying to download a huge file or some kind of P2P torrent and it's full of corruptions or errors and takes ages because it can't find the bits it wants, would that get picked up by DLM? Would unplugging the ethernet from the modem to the router and connecting a PC direct to the modem be seen as a disconnection? BTW I'm on TalkTalk if that makes any difference.
