For certain W-WAN modules LAPB is used to perform multiplexing of serial channels. If
using LAPB for X.25 over ISDN or serial then these settings should be ignored. These
settings should not be changed unless under the instruction of technical support.

When enabled configures the LAPB instance to be used for multiplexing of serial channels
instead of X.25.
