Eeyore said:Yes. The modem connection is simply a pass-through.
Correct. One of the biggest problems I've seen with DSL installations is
the condition of the premises wiring, between the telco interface and
the various wall jacks. Over the years, splices and taps get added in
walls, many of questionable quality. If you depend on locating every
telephone device and installing a filter on every one, one day, someone
will find a forgotten jack and plug a phone in there, without a filter.
The best practice I've seen is to install a tap just after the telco
interface and run that as a single run to a dedicated DSL outlet. Then,
immediately following that tap, install the DSL filter and feed the
existing premises circuit(s) from the output of that.
The interesting analysis in this case would be how that filter behaves
as its load varies.
