VDSL C OMMANDS
29-84
Loss of power Number of seconds during which there was loss of power
Errored seconds Number of seconds during which there was one or more
CRC anomalies, or one or more Loss of Signal (LOS) or
Loss of Framing (LOF) defects
Severely errored
seconds
Number of seconds containing 18 or more CRC-8
anomalies, one or more Loss of Signal (LOS) defects, one or
more Severely Errored Frame (SEF) defects, or one or more
Loss of Power (LPR) defects.
Unavaliable seconds Number of seconds during which the VDSL transceiver is
powered up but not available
Ethernet Receive Performance Counters
Frames Number of frames (bad, broadcast and multicast) received.
Bytes Number of bytes of data received on the network. This
statistic can be used as a reasonable indication of Ethernet
utilization.
Pause Frames Number of MAC Control frames received with an opcode
indicating the PAUSE operation.
Broadcast Frames Number of good frames received that were directed to the
broadcast address. Note that this does not include multicast
packets.
Dropped Frames Number of events in which frames were dropped due to lack
of resources.
Alignment Errors Number of alignment errors (missynchronized data
packets).
Oversize Number of frames received that were longer than 1518
octets (excluding framing bits, but including FCS octets) and
were otherwise well formed.
Undersize Number of frames received that were less than 64 octets
long (excluding framing bits, but including FCS octets) and
were otherwise well formed.
CRC Errors Number of CRC errors (FCS or alignment errors).
Carrier Sense Errors Number of times that the carrier sense condition was lost or
never asserted when attempting to transmit a frame.
