Description
This message provides the user with a number of statistics on a per link basis. If the
user sends the message status set to 1 the statistics are reset after being read.
Parameters
The DVR_MSG_R_L1_STATS message includes the following parameters:
duration
Duration in tenths of a second since the statistic counters were last reset.
abort_cnt
The number of aborts received on the link.
CRC_errs
Number of CRC errors received on the link.
length_errs
The number of received frames that were designated as either too long or too short for
a configured protocol.
rx_overrun
The number of times that the receiver was forced to discard incoming frames as a
result of there being no internal buffers available to receive the incoming data. This is
a count of the number of events rather than a count of the number of frames
discarded.
receiver_busy_cnt
The number of times the receiver has entered the busy state as a result of the number
of internal buffers falling below a set threshold.
rx_frame_cnt
The number of (error-free) frames received on the link, excluding any duplicate frames
that are discarded as a result of the internal filtering mechanism.
tx_frame_cnt
The number of frames transmitted on the link excluding any repeated frames that are
generated automatically (for example, repeated FISUs or LSSUs).
rx_busy_status
Normally set to 0, but in the event of the receiver being in the a “busy” state (where
the number of internal buffers falls below a fixed internal threshold), this field is set to
1.
