I have a DSL modem at home and I don't see any trace of interference on 160 (or
any other band) from the modem. I do sometimes cause the modem to lose sync
when I transmit but that's a different issue.
Supposedly the DSL signaling spectrum has notches defined specifically in the
amateur bands to avoid interference. I have no idea if and how well these are
implemented in practice, but certainly my experience doesn't indicate anything
negative.
