Functional Notes
The following is a list of output messages from the show interfaces shdsl command:
Equipment Type
Line Rate
Alarms
Loop Status
Loopback State
SNR margin
61200510L1-35E
Shows whether the unit is operating in CPE (NT) mode or CO (LT) mode.
Shows the current line rate. The line rate is the data rate + 8 kbps.
Therefore, a rate of 2056 kbps implies an actual data rate of 2048 kbps.
Shows the current alarm conditions. Possible alarms are:
• LOS
• LOSW - Loss of synchronization word (related to frame sync)
• Loop attenuation (loop attenuation margin threshold has been
reached or exceeded; this threshold is user selectable and disabled
by default)
• SNR margin (SNR margin threshold has been reached or
exceeded; this threshold is also user programmable)
• CRC
• Segment defect
• Segment anomaly
Shows additional information about the loop status as well as the
Embedded Operations Channel (EOC). Possible messages are:
• SHDSL training complete (marginal signal quality). Establishing
EOC...
• SHDSL training complete (marginal signal quality). EOC is up.
• SHDSL training complete. EOC is down.
• SHDSL training complete. EOC is up.
• SHDSL training in progress.
Shows the state of local and remote loopbacks. Possible local loopback
messages are:
• Local dual-sided loopback
• Local customer transparent loopback
• Local customer non-transparent loopback
• Local transparent network loopback
• Local non-transparent network loopback
• No local loopbacks
Possible remote loopback messages are:
• Remote dual-sided loopback
• Remote customer transparent loopback
• Remote customer non-transparent loopback
• Remote transparent network loopback
• Remote non-transparent network loopback
• No remote loopbacks
Shows the current, minimum, and maximum signal-to-noise ratio of the
line. These may be cleared using the clear counters shdsl <slot/port>
command.
