This parameter specifies the layer 2 data link layer transport used.  When se-
lected as PPP (def), the Express L768/L1.5 will negotiate PPP over the HDSL 
interface.  This would be used mainly for campus wiring applications.  Param-
eters for controlling the PPP negotiation are in the Configuration/PPP Profile 
menu.  Frame Relay should be selected when the Express L768/L1.5 is con-
nected to a Frame Relay switch.  The Configuration/WAN/Frame Relay menu 
is used for controlling the Frame Relay parameters.
