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 de fe ct

• 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 (mar ginal 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 ne twork loopback

• Local non-tran sparent 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

command.
