Protocol Tab
The Protocol tab lets you choose the protocol settings for your ISDN line.
By default, 'PPP' is enabled. Both ‘PPP’ and ‘Multilink PPP’ require that a PPP communications
stack be installed on your computer. Note that the protocol you choose must match the
protocol on the receiving system.

check with your ISDN Service Provider.
•For the ‘BACP’ tab to be visible (see page 65), the protocol must be set to ‘MultiLink PPP’.
•For the ‘X.25’ tab to be visible (see page68), the ‘Enable Always On / Dynamic ISDN
(AO/DI)’ option must be enabled.
About MultiLink P PP
•To obtain maximum performance when using the MultiLink PPP protocol, your
computer's serial port should be capable of 230.4 kbps transfer. Macintosh computers
that have serial ports capable of 230.4 kbps include all PowerMacintosh computers
(except for the 52xx, 62xx, and 6300 models) and AV Macintosh computers. Check the
user manual that came with your system or consult Apple's technical librar y at
http://til.info.apple.com/.
•Multilink PPP does not support the callback feature used by some servers.
•When using Multilink PPP for incoming calls, only SPAP or PAP authentication are
supported.
