Comparing the number of blocks transmitted with the number of retransmits needed to get data
over the link can indicate a line problem. Comparing the blocks received and receive block errors
indicates the same problem from the other end of the link. Comparative numbers that you might
encounter could be 10,000 blocks transmitted (or received) with 500 or 1000 retransmits (or
receive block errors). Link alarms simply tell you that there are some sort of problems on the link.
You will find that the link alarms numbers will correspond to the retransmit and receive block
numbers. Specifically, a link alarm means that it has been 10 seconds since the DataTalker has
received an acknowledgement. Normally, three acknowledgements are received during a 10-
second period.
The remote down entry means that the DataTalker has sent data 30 times and could not get it
through (the link has been broken).
