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.
