What is RFC 1490? 1-7
connection. RFC 1483 is a conduit for multiple protocols such as IP and
IPX, which are encapsulated and passed across the communications
datalink.
The OfficeConnect Remote 840 supports RFC 1483 and can establish a
RFC 1483 connection to other devices supporting RFC 1483.
Benefits of Using RFC
1483
RFC 1483 offers interoperability of multi-vendor equipment and
identification and aggregation of multiple protocol packets into one data
stream.
What is RFC 1490?
It is a protocol standard that describes an encapsulation method for
carrying network interconnect traffic over a Frame Relay backbone. It
covers aspects of both Bridging and Routing.
The OfficeConnect Remote 840 supports RFC 1490 and can establish a
RFC 1490 connection to other devices supporting RFC 1490.
What is PPP?
The Point-to-Point Protocol (PPP) is a WAN protocol. It is a single or
multi-link interface between two packet switching devices, such as a
bridge or router. A PPP link may be created between the OfficeConnect
Remote 840 and a remote router after they connect. PPP is an efficient
conduit for multiple protocols such as IP and IPX, which are encapsulated
across the communications datalink.
PPP provides built-in negotiation for addresses and connection
parameters, and it can route multiple protocols over a single link.
The OfficeConnect Remote 840 supports PPP and can establish a PPP
connection to other devices supporting PPP.
Benefits of Using PPP PPP offers interoperability of multi-vendor equipment, and support for
dynamic configuration between the connecting devices.
What is DHCP?
Dynamic Host Configuration Protocol (DHCP) is designed to provide a
centralized approach to configuring IP addresses and parameters.
When a workstation is configured for automatic assignment of IP
addresses, it broadcasts a request on the LAN. The DHCP Server responds
