I have 2 T1' s between a 7205 and a 2600. My original problem was that when we brought up the second T1 it was up/down and nobody could figure out why (TAC or Telco). So I move it to a new interface on the 7200 and it came up/up, I figured it was a bad port on the 7200. Well that worked for a few hours then the original T1 suddenly went up/down and showed the exact same problems that the other had(interface resets, input errors,etc). I had these 2 T1's in a multilink bundle, but that doesn't seem to matter, the problem still exists weather its bundled or not.  The 2600 has a total of 3 T1's, 2 of which are bundled, the other goes to another site,one of the T's in question is in a NM-2W, are there any known issues with this router and multiple t's and/or the NM-2W module? I'm thinking the router cant handle 3 T1's and is crapin out.
