54.4 Statistics ADSL Commands

Use these commands to display ADSL port statistics.

Table 135 ADSL Statistics Commands

COMMAND DESCRIPTION P

statistics adsl show [portlist] Displays ADSL port connection statistics including the status

(V for enabled, - for disabled), ADSL operational mode,

upstream and downstream maximum rates, up time and the

number of errored seconds.

M/L

statistics adsl linedata

Shows the line bit allocation of an ADSL port.

Discrete Multi-Tone (DMT) modulation divides up a line’s

bandwidth into tones. This command displays the number of

bits transmitted for each tone. This can be used to determine

the quality of the connection, whether a given sub-carrier loop

has sufficient margins to support ADSL transmission rates, and

possibly to determine whether certain specific types of

interference or line attenuation exist. See the ITU-T G.992.1

recommendation for more information on DMT.

The better (or shorter) the line, the higher the number of bits

transmitted for a DMT tone. The maximum number of bits that

can be transmitted per DMT tone is 15.

“upstream carrier load” displays the number of bits transmitted

per DMT tone for the upstream channel (from the subscriber’s

DSL modem or router to the IES-612-51).

“downstream carrier load” displays the number of bits received

per DMT tone for the downstream channel (from the IES-612-

51 to the subscriber’s DSL modem or router).

The bit allocation contents are only valid when the link is up.

M/L

statistics adsl lineinfo

Shows the line operating values of an ADSL port. M/L

statistics adsl lineperf

Shows the line performance counters of an ADSL port. M/L

statistics adsl linerate

Displays the line rate for the specified port(s). M/L

statistics adsl 15mperf

<portlist>[count <0~96>]

Displays line performance statistics for the current and

previous 15-minute periods.

count <0~96>: Specify for which 15-minute interval (0~96)

you want to display performance statistics. 0 is the current 15

minutes.

M/L

statistics adsl 1dayperf

Displays line performance statistics for the current and

previous 24 hours.

M/L

adsl linediag setld <port> Performs line diagnostics on the specified port. The ADSL port

must be set to ADSL2 or ADSL2+ ADSL operational mode and

have a connection. It takes about one minute for the line

diagnostics to finish.

H/H

adsl linediag getld <port> Displays the line diagnostics results after using the line

diagnostics set command on an ADSL port. Use the line

diagnostics results to analyze problems with the physical

ADSL line.

Note: Wait at least one minute after using the line

diagnostic set command before using this

command.
