As self install is now the way to go , most Isp's that I know of, do not now use the Openreach Modem. Even BT use a combined Modem/Router HH5, Sky use there own Hub, so cannot believe that BT do not accept a line fault unless you are using equipment that they do not supply any more .

Quick update:

beta r48494 received from Draytek support.
Modem code: 574307
DLM reset line yesterday.
Back to full 80/20 synch, no interleaving, ping to bbc.co.uk coming in at 4-5ms (as opposed to 38 - 44 before).
Minor trouble with hardware acc enabled (TCP acks get lost?!), but firmware perfectly stable.
Clients pleased as webserver responsive and VPN stable.
Looking forward to release.
