WAN Datalink Protocol Configuration Menu
NOTICE:
The WAN Datalink Protocol Configuration menu sets up the IAD
internet link for Level 2 Transmission Convergence onto the physical
link. The following generic description of the options listed on this
menu are for information only. Specific encapsulation options are
shown and selected when configuring ATM PVCs (refer to page 4-19)
or Frame Relay DLCIs (refer to page 4-26).

Raw HDLC
Level 2 frame delineation, link control services, and error detection are provided
at physical interface for non-encapsulated transport of IAD payload between
two points.

Cisco Compatible HDLC
Same Level 2 functionality as described under Raw HDLC above, but with
awareness of Cisco-implemented HDLC control field changes (e.g.,
modifications in the control bytes to allow transparent implementation of the
Cisco Discovery Protocol).

IP-Plus Compatible HDLC
Provides support for IP Headers in the HDLC payload.
PPP (Over Raw HDLC)
Point-to-Point over raw HDLC encapsulation.
