Name Off Len Off Len Description
TxFAIL_CARIER_CHECK - - 60 8 Send failure—Carrier check
failed. The data link did not
sense the receive signal that
is required to accompany the
transmission of a frame. Indicates
a failure in either the transmitting
or receiving hardware. Could
be caused by either transceiver,
transceiver cable, or a babbling
controller that has been cut off.
TxFAIL_SHRT_CIRCUIT - - 68 8 Send failure—Short circuit
3
.
There is a short somewhere in the
local area network coaxial cable
or the transceiver or controller
/transceiver cable has failed.
This indicates a problem either in
local hardware or global network.
The two can be distinguished by
checking to see if other systems are
reporting the same problem.
TxFAIL_OPEN_CIRCUIT - - 70 8 Send failure—Open circuit
3
.
There is a break somewhere in the
local area network coaxial cable.
This indicates a problem either in
local hardware or global network.
The two can be distinguished by
checking to see if other systems are
reporting the same problem.
TxFAIL_LONG_FRAME - - 78 8 Send failure—Frame too long
3
.
The controller or transceiver cut off
transmission at the maximum size.
This indicates a problem with the
local system. Either it tried to send
a frame that was too long or the
hardware cutoff transmission too
soon.
