Functional Notes

The following is a list of output messages from the show interfaces shdsl command:

Equipment Type	Shows whether the unit is operating in CPE (NT) mode or CO (LT) mode.
Line Rate	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.
Alarms	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
Loop Status	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.
Loopback State	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
SNR margin	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.
