9. Conditions for 56K connection
Under certain circumstances your Trust 56K USB can receive data at a speed of a maximum of 56,000 bits
per second. If it is not possible to connect at 56,000 bps, the modem will switch back to a lower speed
automatically.
A speed of 56,000 bps is only possible for receiving data under the following circumstances:
•You are connected with the Internet;
•Your Internet provider has a 56,000 bps compatible connection station at the number you are calling;
•You are connected with the Internet provider via a modern (digital) telephone exchange. If unsure, ask
your telephone company;
•You are using a direct analog outside line and are not connected via an internal telephone system or
ISDN.
The maximum speed under all circumstances and for sending data is 33,600 bps.
Note: The speed depends on the quality of the telephone line. The Trust 56K USB Modem will
reduce the speed if the connection is poor.
