Table 6-1.
Diagnostics Options
Selftest
D-A
Displays the results of the last disruptive self-test of the DSL card. This self-test is only
performed on power up of the system or a reset of the card. Each subsystem
(processors, memory, and interfaces) reports pass or fail. If all subsystems pass, the
card has passed self-test. If a subsystem fails, reset or replace the card.
You can determine when the self-test occurred by reading the elapsed time since the
last reset on the card.
Alarms (Card Alarms)
D-B
Displays all active card alarm conditions.
Major alarms include Selftest Failure, Processor Failure (Sanity Timer), and DSL or
Ethernet Port Failures. Refer to
Table 6-2,
Major Alarms.
Minor alarms include Config Error (configuration has been corrupted) and Threshold
Exceeded for DSL Margin or Link Down events. Refer to
Table 6-3,
Minor Alarms.
DSL Packet Echo Test
D-C
Gives the user the ability to conduct a nondisruptive packet test between the DSL card
and Hotwire Service Node endpoint. Test packets are sent to the Service Node at
10 percent of the line rate and echoed back to this card, where they are counted and
checked for errors. The running time of the test can be specified and the test will
continue until the specified time has elapsed or the test is stopped.
Results include packets sent, valid packets received, errored packets received, errored
seconds, and elapsed time of the test.
NOTE:
You can specify the DSL port number but only one port can be tested at a
time.
SN Selftest
D-D
Gives the user the ability to perform a power-on Service Node self-test. A port number
can be selected to perform the test.
NOTE:
Entering yes in the Reset SN field will temporarily disrupt the data path on
the specified DSL port while the SN resets.
