The modem is noisy when it dials and connects
When your modem tries to connect to another modem, it begins handshaking.
Handshaking is a digital “getting acquainted” conversation between the two
modems that establishes connection speeds and communication protocols. You
may hear unusual handshaking sounds when the modems first connect. If the
handshaking sounds are too loud, you can turn down the modem volume.
