[c-nsp] strange problem about stm-1

[ying-xiang]

hi,everyone

    i got a very strage problem about stm-1 which installed in a cisco 7606-s chassis with a sup-32 engine.

according to the 3-7-3 divide the stm-1 into 63 2MB E1 ports that are connected to our branch devices,respectively

recently,many 2MB lines have encountered varying packet loss and the interesting thing is the packet loss just

disappear after changing the lines ip address?!

   could anybody give a reason can explain this ?
