What is a Remote Site?

MAC layer addresses are pre-pended in the ethernet header over the
Wide Area Connections. Address Resolution procedures (ARP), are used
to dynamically learn the MAC address of the remote router.
What is a Remote
Site?
The OfficeConnect Remote 840 can be configured to route IP or IPX,
and/or bridge other protocols between workstations on the Local Area
Network (LAN) and up to 16 remote locations over an ATM or Frame
Relay Wide Area Network (WAN). This is illustrated in the diagram below,
showing the local LAN simultaneously connected to a remote office and
the Internet.
Figure 1–2 Connection to a Remote Internet Network
Data is transmitted to and from remote sites through ATM or Frame
Relay. With ATM, each VC has a configured Quality of Service (QOS) and
is identified by a Virtual Path Identifier (VPI) and a Virtual Channel
Identifier (VCI). With Frame Relay, each Virtual Circuit is identified by a
DLCI. Obtain these parameters from your Service Provider.
The data is framed in either PPP, RFC 1483 or RFC 1490 encapsulation,
which also is specified by your Service Provider.
The IP, IPX, and bridge protocols transmit over the ATM VCs. When a
remote site is configured to route IP, there will be a corresponding remote
network IP subnet address and (optionally) a local WAN interface address
