If the ACSE Option is enabled, then in addition to the total count,
there are also separate counters for total number of data frames and
voice (RTP) frames. The voice frames count includes fax frames. This
is true also for Subscriber Units that do not support voice in cells
where the ACSE Option in the AU is enabled. In this case the Voice
count should be 0.
! Total retransmitted frames – Displays the total number of
retransmissions of frames (counts all unsuccessful
transmissions/retransmissions).
If the ACSE Option is enabled, then in addition to the total count,
there are also separate counters for total number of Data frames
and Voice (RTP) frames. This is true also for Subscriber Units that
do not support voice in cells where the ACSE Option in the AU is
enabled. In this case the Voice count should be 0.
! Total Tx errors – Displays the number of transmit errors that have
occurred. The total number of Tx errors includes transmissions that
were not acknowledged properly, transmissions that were aborted
and transmissions that were delayed for various reasons (e.g. not
enough time until the end of the current dwell period).
In addition, the following special counters are displayed to indicate
the reason for the error:
" H/W: An internal hardware problem in the modem.
" ABR: The transmission was aborted before completion because
of internal problems in the DSP.
" CSL: The transmission was cancelled because the modem was
busy in receiving data.
" ACKTOUT (Acknowledge Timeout): The frame was not
acknowledged within the time defined by the Acknowledge
Delay Limit parameter.
" FAIL: There was an internal timeout in the modem.
" ACKCRC: There was a CRC error in the ACK message.
" RTSC: The RTS was sent but no CTS was received (RTS
collision).
" EOD (End of Dwell): There was not enough time left to transmit
the message
! Total received frames from wireless – Displays the total number
of frames that were received from the wireless media. The count
includes data, control and wireless management frames, including
beacons received from the AU. The count does not include frames
that were discarded internally, bad frames and duplicate frames.
! Total received data frames – Displays the total number of data
frames received from the wireless media, including duplicate frames
(see Duplicate frames discarded, below). In addition to the total
count, there are also separate counts for data frames according to
the receive priority queue to which they were routed (Low or High).
