What Is the
OfficeConnect
Remote 840?
The OfficeConnect Remote 840 is a stand-alone BRouter with data
interfaces to a Local Area Network (LAN) and a Wide Area Network
(WAN). The Symmetric Digital Subscriber Line (SDSL) port composes the
WAN interface, which can support Point-to-Point protocol (PPP), RFC
1483, or RFC 1490 connections. The LAN port is a twisted-pair Ethernet
10Base-T interface. Additionally, the OfficeConnect Remote 840 has a
standard serial interface console port.
The OfficeConnect Remote 840 allows one or more networked
workstations to connect to other computers on a remote LAN. Once
connected, local users (a local branch office) can communicate with
remote computers (the main office) as if they were connected locally (see
the figure below). The OfficeConnect Remote 840 moves data back and
forth quickly, and accesses any program or file you would ordinarily use
on the network.
