PPP or multilink PPP
•

Internet Configuration
You can only gain ISDN access to the Internet if you have a contract with an Internet Service Provider (ISP) who works with
ISDN access. You will need the following information from your ISP to configure the Proxima ISDN Lite:
•
ISDN access number (to be entered into the PC program)
•
The protocol used, for instance PPP (command: AT&O7), which has to be configured in the Proxima ISDN Lite
•
Access protocol (which has to be entered into the PC system software or the Internet software), usually PPP
You may need additional information to configure the Internet access software, like TCP/IP address, user name, password,
etc. For more information, consult the software manual and contact your ISP.
