Customer got a new naked VDSL connection provisioned last Friday. It synched up but would not authenticate.

The Draytek modem reported "no response from server" and Xtra confirmed from the RADIUS logs that "an invalid character was received"

After much nashing of teeth during long phone calls to Manilla?, customer chose to downgrade to ADSL which was promised to be possible within a few hours and without any change at the Exchange .. is this possible by the way?

Ok now it is a day later and we have ADSL signal synching up but still no authentication .. and I am trying to find out what the RADIUS logs are saying this time ..

The VDSL synch rate was 24M/1.5M and the ADSL rate is 15M/1M .. there is no splitter installed which is another interesting issue, I thought that for VDSL-installs a splitter was mandatory and part of the Chorus provisioning?

Can anyone help here to get this sorted? I am assuming that this is a jumpering issue at the Exchange?

cheers mark
