There are DSL Modems that are also routers, but a DSL modem is *really*
a modem, in that it MODulates and DEModulates the signal over the phone
line to and from a digital stream. Unlike a normal dialup modem, the
DSL modem uses a frequency range that is far outside of the range of
human hearing, and won't interfere with normal voice services.
That's why you often need a filter, because now you've got two services
using the same medium. You'll want to put the filter on every
non-DSL-modem device, leaving the DSL modem unfiltered.
