Fast DSL?

I'm hanging out at my parent's house for Christmas. First thing I noticed is that they have a new DSL modem/gateway from 2Wire. I just checked the connection speed (www.dslreports.com) to New York and it was ~5Mbits. I thought DSL speed was a lot slower than cable modem; I guess that's not the case anymore. I get about ~10Mbits but that's the fastest cable modem service Time Warner offers.
