>>> I asked what was the implication of plugging a phone into a DSL line without a splitter.
Depends if a modem/router is also plugged in as well. If its just the phone then its ok.
The
splitter is there to separate 2 different frequencies.
However if a phone and router on on the line then the adsl data will cause interference on the phone which may well be clearly audible.
It will also likely cause problems with the adsl connection.. speed could be quite a bit slower, there could be noise on the adsl line.. which can materialise as lower SNR, data errors, and even loss of sync.
