It's basically playing what your computer is 'hearing' down the phone line. The squelling is data, and the pings are kind of just that - a sort of confirmation that a handshake's taken place.
If you go into the properties of your modem you can probably untick a box which plays the data over the speaker, but a lot of people actually like it as it give audio confirmation that the connection process is working (if it doesn't work you don't hear the pings at the end).
If it's occuring in the middle of things, it's suggesting it's lost connection and is having to redial.
