DESCRIPTION
Clears the current or historical 15-minutes and 1-day DSL line
status for the specified DSL ports.
Displays the current or historical 15-minutes and 1-day DSL line
status for the specified DSL ports.
Displays the detailed DSL line information for the specified DSL
ports.
Displays the detailed DSL channel information for the specified
DSL ports.
Displays the DSL band information for the specified DSL ports.
Displays the DSL medley psd information for the specified DSL
ports.
Displays the DSL Quiet Line Noise (QNL) level information for the
specified DSL ports.
Displays the DSL SNR information for the specified DSL ports.
Displays the DSL HLOG information for the specified DSL ports.
These channel characteristics can be used in analyzing the
physical condition of the ADSL or VDSL line. The format provides
magnitude values in a logarithmic scale.
Displays the number of bits transmitted for each DMT tone for the
specified DSL ports. The better (or shorter) the line, the higher
the number of bits transmitted for a DMT tone. The maximum is
15.
Performs the DSL Dual End Loop Test (DELT) test on the specified
DSL ports. ADSL ports must use ADSL, ADSL2, or ADSL2+
operational mode and have a connection. VDSL port must use
VDSL2, ADSL2 or ADSL2+ operational mode and have a
connection. The subscriber device must also support DELT.
It takes about one minute for the loop diagnostics to finish.
Displays the DSL DELT test results for the specified DSL ports. Use
the loop diagnostics results to analyze problems with the physical
ADSL or VDSL line.
Performs the Single End Loop Test (SELT) on the specified DSL
ports to check the distance to the subscriber.
Note: The port must have an open loop. There cannot be a DSL
device, phone, fax machine, or other device connected to
the subscriber's end of the telephone line.
Displays the SELT results (such as line type and loop length) for
the specified DSL ports.
Performs an OAM F5 loopback test on the specified ATM PVC of the
specified DSL port.
Displays the OAM F5 loopback test results for the specified DSL
port.
