Has anyone done the following configuration. I have the original Cisco 804 router (not the new 804 IDSL). I used to have ISDN and that works fine. I just upgrade my link to IDSL and my ISP (Covad) provides a Netopia R3100-T. I tried to simulate the configuration on the 804 but could not get it to work. I was able to get up/up on the bri0. This is a similar configuration I used. http://www.ieng.com/univercd/cc/td/doc/product/access/acs_fix/800/10368_01. htm#xtocid732918 My thinking is the original 804 has NT1 built in (assuming 804 IDSL router doesn't have NT1 hence the lower list price) and that didn't bode well with and IDSL link. _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
