Tackle line noise

One of the most frequent causes of an interruption to your dial-up connection is ‘line noise’. What is simply an annoyance for a phone call becomes for your internet connection something much worse – disconnection.

The problem is that your dial-up modem is more sensitive than human ears and while snatches of other people’s calls on a crossed line, hissing and popping are bad enough, your modem can hear sounds that are beyond the range of human hearing.

je trouve modem commuté/modem à composition automatique, etc mais ce n'est guère utilisé en France (cf Google).
Est-ce que modem téléphonique pourrait convenir ? (ce doc s'adresse au grand public et doit donc utiliser un voc le plus clair possible)
merci !
