could connect about 50 systems per port to completely fill up the database (the 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).
Plug and Play
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
PC/Workstation Configuration
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 Address
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.
Dynamic IP Address
If the ISP or corporate network supports Dynamic Host Configuration Protocol (DHCP), a temporary IP address is automatically obtained for the session.
