was looking at an E1 link that is generating lot of CRC errors/slips. The weird thing I see about the link is when i do 'show isdn status', it shows me the following
Layer 1 Status:
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
TEI = 0, Ces = 1, SAPI = 63, State = TEI_ASSIGNED
Now, in normal circumstances you see either 'Multple_frame_established' (which means layer 2 is ok) or 'tei_assigned' (which means its not ok) but I'm baffled why the two of them are there together ? what does that indicate. Ofcourse, the link has problems routing voice calls but am not sure what to interpret the output of above command as ? any help wud be appreciated, thnx.
