Output Fields

Table 1 lists only output fields that are specific to the show interfaces (ATM-over-SHDSL) command. For information about all other output fields, see Table 92 under the show interfaces (ATM) command.

Table 1: ATM-over-SHDSL show interfaces Output Fields

Field Name	Field Description	Level of Output
SHDSL alarms	Number and type of SHDSL alarms. See "SHDSL media" for details.	detail extensive none
SHDSL defects	Number and type of SHDSL defects. See "SHDSL media" for details.	detail extensive none
SHDSL media	Information about the SHDSL 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: LOSD—Loss of signal was detected at the remote application interface. LOSW—Loss of sync word. A message ID was sent. ES—Errored seconds. One or more cyclic redundancy check (CRC) anomalies were detected. SES—Severely errored seconds. At least 50 CRC anomalies were detected. UAS—Unavailable seconds. An interval occurred during which one or more LOSW defects were detected.	extensive
SHDSL status	Operational information for ATM-over-SHDSL interfaces. Line termination—SHDLS transceiver unit- remote (STU-R) (Only customer premises equipment is supported.) Annex—Either Annex A or Annex B. Annex A is supported in North America, and Annex B is supported in Europe. Line mode—SHDSL mode configured on the G.SHDLS Physical Interface Module (PIM), either 2-wire or 4-wire. Modem status—Data. Bit rate (kbps)—Speed of data transfer on the ATM-over-G.SHDSL interface, in kilobits per second. Last fail mode—Code for the last interface failure. Framer mode—Framer mode of the underlying interface: ATM. Dying gasp—Ability of a J Series router that has lost power to send a message informing the attached DSL access multiplexer (DSLAM) that it is about to go offline: Enabled or Disabled. Framer sync status—Framer synchronization status: In sync or Out of sync (OOS). Chipset version—Version number of the chipset on the interface. Firmware version—Version number of the firmware on the interface.	detail extensive none
SHDSL statistics	Loop Attentuation (dB)—Attenuation in decibels. Transmit power (dBm)—Power of the transmitting interface. Receiver gain (db)—Power increase of the receiving interface, in decibels. SNR sampling (dB)—Signal-to-noise ratio at a receiver point, in decibels. CRC errors—Number of cyclic redundancy check errors. SEGA errors—Number of segment anomaly errors. A regenerator operating on a segment received corrupted data. LOSW errors—Number of loss of signal defect errors. Three or more consecutively received frames contained one or more errors in the framing bits. Received cells—Number of cells received through the interface. Transmitted cells—Number of cells sent through the interface. HEC errors—Number of header error checksum errors. Cell Drop—Number of dropped cells on the interface.	detail extensive
