1) Operating Mode set to G.992.1, G.DMT or ANSI T1.413 iss 2 but not G.Lite or G.992.2
2) VPI/VCI set to 0/100
3) Protocol set to PPP over ATM (PPPoA) (RFC 2364) with VC-multiplexed encapsulation
4) Username and password set according to the user ID that the customer has on the service they are trying to connect to (either ISP or corporate). The user name must be set to the user ID followed by an @ symbol followed by the domain name eg user@isp.co.nz
Note that for the Xtra Velocity service the customer user ID has ".xadsl" appended to it ie "user.xadsl@xtra.co.nz" Other ISPs may or may not have similar requirements, the customer will need to check this with their ISP.
The customer should be supplied with instructions as to how they can change this user name without altering other settings, for example whenever they want to change ISPs or connect to a corporate network.
Note that a single IP address is given out as part of this service. If the modem is external, with an Ethernet connection to the customer, then it must have some form of network address translation (NAT) inside it. The settings for doing this need to be supplied by the modem manufacturer.
The modem may also have the ability to act as a DHCP server and hand out internal IP addresses to PC clients. Failing that, it will have a setting to configure the internal IP address of the modem. Again, the manufacturer must supply instructions on how to do this, that also tell the customer what setting to use under what circumstances.
Any other application layer proxying, firewall or other functionality within the modem that customers intend to use must also be included in manufacturers instructions.
