Figure 12-3. Link Diagnostics Screen (I6)

Term Used in I6 Meaning

Octets Compressed data units. If the number of octets is greater than the number of

characters sent, the devices probably used MNP5 compression on an already

compressed Þle, and the result was expanded data.

Line Reversals The number of times HST-mode devices switched the high- and low-speed chan-

nels.

Blers Errors in data and protocol

blocks. If there were many block errors, your receiver

may have experienced problems on the line.

Blocks Resent These represent blocks the remote device re-sent due to Blers.

Link Timeouts Protocol detection problems: Communications were severed momentarily, and

the devices probably recovered. This does not indicate the retry timeout.

Link NAKs Negative acknowledgments (one or more blocks).
