Your phone line may not support or may only intermittently support a 56K connec-
tion. There are many conditions that must be met before a 56K connection can be
established. The telephone company must have you connected to the (Public Switched
Telephone Network) in a particular way. The modem you are calling must also sup-
port the same protocol.
The drivers for your modem are constantly being refined to address problems with
compatibility, interoperability, and performance. Conditions that were thought in-
surmountable only months ago are now things of the past. As the industry converts
to the new V.90 standard, current problems of connectivity and interoperability could
also be things of the past. Check for driver upgrades on a regular basis. A problem
connecting to a particular provider might be fixed by a simple software upgrade.
