I do have two Lans (A. w2k server - 14 w2k PCs / B. w2k server - 10 w2k PCs) connected with cisco 1720 routers via 128 ISDN lines. --> I do wish to use ADSL instead of ISDN! 1. Is it possible and HOW? (cisco has ADSL modules for 1720) 2. Will I get a better connection speed? 3. 1720 have voice modules. How easy (if possible) to use voice with ADSL? 4. I found the routers (I did not set up them by myself). How difficult is to do that? Thank you for your time and advise!
