ADSL Statistics

Field Description
Operational information for ATM-over-ADSL interfaces.
• Modem status—Status of the modem: Down, Training, or Showtime.
• DSL mode—Configured line type of the digital subscriber line: adsl2plus,
ansi-dmt, auto, itu-dmt, or itu-dmt-bis.
• Last fail code—Reason for failure: ATU-C not detected, incompatible line
condition, protocol error, message error, spurious ATU detected, forced silence,
unselectable operation mode, or none.
• Subfunction—Specified analog front-end chip and discrete front.
• Seconds in showtime—Number of seconds the ADSL connection is in
showtime.
Information about ADSL media-specific defects that can prevent the interface
from passing packets. The following information is displayed for each defect:
• Seconds—Number of seconds the defect has been active.
• Count—Number of times that the defect has gone from inactive to active.
• State—State of the error. A state other than OK indicates a problem.
The possible defects are as follows:
• LOF—Loss of frame.
• LOS—Loss of signal.
• LOM—Loss of multiframe.
• LOP—Loss of pointer.
• LOCDI—Loss of cell delineation for an interleaved channel.
• LOCDNI—Loss of cell delineation for a noninterleaved channel.
Information about the ADSL terminal unit-remote (ATU-R) at the far end of
the connection and the ADSL terminal unit-central office (ATU-C) at the near
end:
• Attenuation (dB)—Attenuation in decibels.
• Capacity used (%)—Percentage of capacity used.
• Noise margin (dB)—Maximum extraneous signal allowed without causing the
output to deviate from an allowable level, in decibels.
• Output power (dBm)—Amount of power used by the ATM-over-ADSL
interface.
• Bit rate (kbps)—Speed of data transfer on the ATM-over-ADSL interface, in
kilobits per second.
• CRC—Number of cyclic redundancy check errors.
• FEC—Number of forward error corrections.
• HEC—Number of header error checksums.
• Received cells—Number of cells received through the interface.
• Transmitted cells—Number of cells sent through the interface.
