Fallback.
The Express 3000 communicates with many different types of tele-
communications equipment including other Express 3000 units,
other ISDN terminal adapters, and PPP-compatible devices. Com-
munication between such devices requires various rate adaption
protocols supporting various bit rates and RS-232 connector set-
tings (protocol type).
PPP Mode
Selects the PPP mode the Express 3000 uses: Point-to-Point (PPP)
Async-to-Sync, Multilink PPP (MP), or PPP with Compression.
