X.75 Dial-In Support for ISDN (LAPB)
X.75 dial-in support is implemented for the German ISDN dial-in remote access

(LAPB). The following are supported:
• Auto-detection of X.75 calls, versus Synchronous PPP calls in ISDN
B-channel
• PPP over X.75
• ClearTCP over X.75
• Auto-detection of PPP versus TTY connection over X.75
• Shell login over X.75
• Call type override for configuring X.75 VPOP
