ISDN isn't DSL. You can't run it on the same wire your phone service
and use filters to allow their simultaneous use. But installing it
yourself is very easy. All you need is a Cat3 (standard telco) cable
run from the NID (network interface device - where the phone lines come
in the house) to where ever you want the ISDN service. The telco hooks
the wires (single pair) together at the NID, tells you which colors to
use at the receptacle, and you just saved yourself US$100-$300.
