The merit dialup network is a good example. It is an extension of the internet that you can reach by phone.
The phone based connection is slower (about 5 MB/hour peak)
There are a few main types,
ISDN - an faster, more expensive connection, geared to permanent connections
You need a modem in your computer, and you must dial up to another computer that has a modem and is connected to the Internet. The slower of the two modems determines the speed of the connection. Typical modem speeds are,
- 28.8/33.3 kbps - moderate speed, inexpensive
- 14.4 kbps - a bit slow for internet access
- 300 bps - just shoot me
