Hi folks,

i've got a cisco 886 router running ios 15.2(1)T1. If I enable "debug atm error" the router shows every second the following error meesage:

ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.ATM_UCC_GetChannelHandler_PQ2CE: wrong ChannelCode.

The adsl line stays connected and there is no packetloss. All interfaces will remain up.

DSL: Training log buffer capability is not enabled

At https://supportforums.cisco.com/message/3464080 the issue was already discussed. According this thread i should upgrade my ios version but my version is even younger that the proposed.

So any ideas?

Regards,

Patrick
