We all know xnet has poor intl. performance, but I'd at least expect something better than this for national traffic?

The address was recently hooked up to a cabinet about 300-400m down the street.

DSL-504T Modem
Stats:
SNR:   down 12 - up 35
Attenuation: 11 - 4
Data rate:    13930 - 165

It's an ADSL1 plan so we should at least be seeing 6mbits or so down. The 128k upload should be able to handle that.
