could You be more specific.
Are You starting a ISP with ADSL lines, or share a singe ADSL line with one other computer with LAN / Serial cable, with what OS etc...
We are an isp already and have a pm3 for dial-up. We have one T1 for a net connection plus the T1 for the pm3.
What sort of hardware software does one need to make adsl avaiable to the users?
From what I know, you can contact your telephone company and close a deal. They will provide the actual [A/X/H]DSL lines to the end-users. You'll have to connect a T3 or two to the telephone-company. The TC will then route traffic to you if users authenticate to your domain (radius, usually).
With only a T1 to the net, you'd better expand your helpdesk to get ready for the complaints.. ;-) Rogier Maas
