upstream bandwidth is limited to 1 Mb/s). If only one virtual port is in use, the
256 entries can be divided over two ports (virtual, Ethernet port).

The ADSL modem is a plug and play device; through the bridge learning
mechanism, it discovers at which side of the bridge workstations are located. It
prevents traffic submitted to the local printer from crossing the bridge. It allows
frames belonging to transmissions with remote workstations to pass over the
ADSL line.
Both the local PCs and remote PCs must be configured properly for end-to-end
connections.

For detailed information on how to configure the PC, contact the ISP or corporate
network administrator. Depending on the network protocols being used (IP, IPX,
AppleTalk, NetBEUI, etc.), the PC configuration can include a wide range of
parameters. The ADSL modem does not interfere with these higher layer
protocols, as it is transparent to all of them.
The TCP/IP family is used as a configuration example (procedures may equally
apply to other protocol families).
Every IP host must have a unique IP address, whether connected to a corporate
network or the Internet. The ADSL modem is transparent to IP protocols; it allows
PCs to operate with both fixed and/or dynamic IP addresses.

Fixed IP addresses are primarily used by corporate network users; LAN
administrators provide them. Before starting, the PC must be configured with an
IP address.
When the PC is started, a connection is established with the remote site through
the automatic exchange of specific TCP/IP messages and bridging operations.

If the ISP or corporate network supports Dynamic Host Configuration Protocol
(DHCP), a temporary IP address is automatically obtained for the session.
You must configure the PC to use BOOTP/DHCP.
