	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.
