Hello, I have very strange problem. Two routers (client and access-server) are connected via E1/PRI (using Siemens ISDN switch). When I simulate short disconnect (several miliseconds) in access server part and switch doesn't recognize any failure strange thing occurs. Router recognizes E1 controller down, all established channels go down and E1 controller goes up. Everything seems OK, but no traffic go throug this connection (encapsulation failed in both routers debugs). When I simulate problem in other side or ISDN switch recognizes failure, everything is OK. >From my investigating it seems that the problems is connected with Balanced module (2CE1B). Module 1FE-2CE-B/U in unbalanced mode hasn't this problem. However I haven't both unbalanced modules yet, so I can properly try it. As for the IOSes, I try a lot of version (12.0.x, 12.0.xT, 12.1.xT etc). The problem is the same. Is there any possibility, how to prolong down state of E1 controller in situation when it go down? I hope it should help to recognize failure for ISDN switch. Thank you any hint. Michal Configuration and "sh ver" of one router (access-server): gcra#sh run Building configuration...
