- Yes.

- Almost all (+99%) calls in US are converted to digital at your local
- company office. From there they stay digital until the local loop of
- the person you call.

- It's sad that we start with digital data, convert it to analog with
- the modem, then the phone company conterts it back to digital,
- switches it to wherever, converts it back to analog for the local
- loop, and then your modem converts it from back to digital for your
- computer.

- Eight conversions per byte for full-duplex! It's amazing this stuff
- works at all.

- There is a better way. See:
