ISP Setup

Hi, AM on the drawing board of setting up an ISP which can handle about 1000 customers on a T1 connection. Can anyone help me with the Network diagram and hardware & software requirements, basically the whole setup. Please. Budget about £30,000

Im asuming you want to have your clients use dialup to connect to your network? basicly you would need a remote access router with modem bank and the T1 connected to your ISP.

Usualy you would rent a rack space in a colo in each city you would want to have dialup customers ( so your subscribers use local number ) and connect to your ISP through 100 Mb or gig ethernet ( cause their router will be next to yours in same building ). with your router having a modem bank for your dialup users.

Thanks for your advice, basically am setting this up in africa. Am ment to supply dial up connection and broadband if possible. My setup need to be all from my hardware rather than colocation from other providers.

any help?

here is the deal to be an ISP offering broadband service you would need alot more bandwidth than a single T1 to your ISP (usualy the ISP would jump straight into a SONET ring with minimum dual OC12's / european SDH STM-4 if supplying broadband services this is minimum) as well you would need to run or lease cable to your subscribers premises. for dial-up and a 1000 users a T1 is still very small ( you could prolly get by with 100 users on the T1 simultaniously ) which means you might be able to subscribe 200 customers if lucky ( most ISP's subscribe at a 4 to 1 ratio). If youd like I could tell you the hardware needed for a dial-up service?

well here.. you need a router with T1/WIC and PRI interface (preferably cisco), a modem bank (bunch of modems), and an authentication server (RADIUS), a T1 ran to your location and ISDN for dial-in or could just use POTS lines.

Im not sure whats up in africa but in the US it would be way more cost affective to have your own RADIUS box and just get ports from a wholesale company that authenticates users to your RADIUS box.
