within the same subnet. When the local side of the WAN interface has an assigned address, it is referred to as being "numbered." Otherwise, it is referred to as "unnumbered."

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 dynamically learned. Otherwise, they must be specified. The diagram below shows a OfficeConnect Remote 840 with 3 VCs and the corresponding IP addresses.

What is RFC 1483 RFC 1483 is a protocol standard that describes two encapsulations 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
