- Do not confuse data grade lines with leased lines. A data grade line is
- simply one that the phone company allegedly checked and made sure was
- "balanced". The only thing they can check, however, is your local loop;
- the circuit between your premises and the central office. A data grade
- line isn't worth the money (in my opinion) because it still has to
- navigate the PSN (Public Switched Network). The only advantage to a data
- grade line is you can bitch at the telco and they are supposed to
- actually pay attention.
-
- A leased line is a point-to-point fixed connection. Both end of the lines
- are balanced and the proper loading for that particular circuit is added.
- The connection is only between the points and no dialing needs to be done.

- Nothing special about ISDN except that you are only going to get an ISDN
- connection to another ISDN customer. It also goes through the PSN.
