For a more in-depth description of “numbered” versus “unnumbered”
interfaces, see Appendix B, “IP Addressing”
.
When PPP is used, both the local and remote WAN addresses can by

methods for carrying network interconnect (Bridging and Routing) traffic
over ATM AAL5.
RFC 1483 is a single-link interface between two packet-switching devices,
such as a bridge or router. An RFC 1483 link may be created between the
OfficeConnect Remote 840 and a remote router after they establish a
