Ras connections

by Sergey Kovzik In reply to Ras connections

multiply lines... what do you mean under access? if you want 12 users connect to your server using their modems - you need some hardware to get their calls. one modem is one line. you can install modems in server - there are cards with 8 (and other quantity too) integrated modems. but you have to provide same number of phone lines. you might think about buying cisco or some other manufacturers access router and connect it directly to your phone provider. you need to call your phone company and ask them about prices and compatible hardware. and you need to ask them about such service as call forwarding - if one line is busy your phone company will automatically switch user to free one.
DSL connection... this isn't dial-up. this is permanent connection to your ISP. you have special modem-router and that all. your RAS isn't related to this thing.
ISDN - same idea as above. But there are different kinds of ISDN. you can have permanent connection or you can have connect on demand. this is again question to your phone company. and you will need again some kind of equipment to handle ISDN connection. If I had choice I'll install cisco 2600/3600 series with ISDN T1 and modems daughterboard - this case you will need NT only for authorization (and even this is optional - cisco has own authorization possibilities), but everything depends on situation. you might not have large budget so it is possible that you'll have simple 2-3 modems installed in your server and your users will use them in their defined time.

Here are various ways to get 12 users connected:

1. 12 phone lines, 12 modems, 12 COM ports (using digiboard or similar for many COM ports). You can give each user their own phone number, or use one number and have the phone company roll over thecalls.

2. 1 ISDN PRI (very expensive line with 23 channels), ISDN router, ethernet from server to router.

3. 6 ISDN BRI lines, 6 ISDN routers, each user calls one channel. Ethernet from routers to server.

4. External phone server box (Shiva, etc.) with built-in modems to handle some number of appropriate phone lines.

5. 1 Internet connect (T1, DSL, ISDN, etc.), appropriate router, ethernet to server, RRAS on server to provide vpn services. Each user connects to internet (any method), and uses tcp/ip to connect to your server and authenticate. Can encrypt data transmissions for security. This is probably the cheapest and best solution.

Good luck.

For allowing 12-client access, u need 12 phone lines connected to 12 modems and linked to ur RAS thru a Multi-port Card (there are models available for 8 & more lines). Another solution can be to use one ISDN (PRI) line with 12 channels configured or 6 ISDN (BRI) lines. You might like to check out ready-made boxes like Shiva LanRover, Access MultiTech or Cisco (don't remember the model name) product.
Would like to know which one helps, as we have a similar setup.
