You can do it multiple ways: 1. old fashioned hunt groups for multiple analog lines. 2. getting a PRI with one outward facing number. 3. talk to your local Bell about what would best suit your needs (digital calls? 56K? 64k? 128K? ISDN? Analog? dialout capability, or just dialin? etc. etc.) --Patrick Darden -----Original Message----- From: John Musbach [mailto:johnmusbach1@gmail.com] Sent: Monday, November 24, 2008 2:15 AM To: nanog@nanog.org Subject: How do dialup ISPs allow multiple clients under one access number? I'm interested in figuring out how dialup ISPs work and have found plenty of info on dialin server setup but not much on how ISPs allow multiple clients under one access number, how do they do it? -- Best Regards, John Musbach
