I'm planning to setup a small ISP with Linux, I'm looking in using ISDN BRI 64k for my starting.
My question is, is it possible to use a ISDN modem connecting to a Linux box and use the pppd to do the routing instead of buying a ISDN router? What's the advantage if i spend more bucks to buy a ISDN router instead of using a direct ISDN modem.
Please give me some more advice on using which hardware combination. How about the 56K DDS ?
I want to compare the price and it's the main concern for me.
