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.
