Table 8-2. Diagnostics Options

Selftest D-A
Displays the results of the last disruptive selftest of the DSL card. This selftest 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 selftest. If a subsystem fails, reset or replace the card.
You can determine when the selftest 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. Minor alarms include
Config Error (configuration has been corrupted) and threshold exceed for DSL margin,
Error Rate, or Link Down events.
Packet Echo Test D-C
Gives the user the ability to conduct a non-disruptive packet test between the DSL card
and HotWire RTU endpoint. Test packets are sent to the RTU at 10 percent of the line
rate and echoed back to this card, where they are counted and checked for errors. You
do not have to specify the IP address of the RTU. The running time of the test can be
specified (15 to 900 seconds), 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: Only one port can be entered at a time.
