Troubleshooting and
Diagnostics
This chapter describes the ASMi-52CQ diagnostic functions, which include:
• Diagnostic tests (loopbacks, LEDs test)
• Status indications, alarms
• SHDSL performance diagnostics
• Troubleshooting procedures.
5.1 Introduction
ASMi-52CQ offers diagnostics for troubleshooting:
• V.54 loopbacks – Local analog and remote digital loopbacks needed to isolate
a failure to a particular element of the transmission system
• Alarm buffer – Contains alarm messages regarding the status of the
transmission system.
All diagnostics options can be invoked from the RADview SNMP management tool
or an ASCII terminal. A combination of the above diagnostics tests is also
possible. Then, examine the alarm buffer messages for any transmission error or
configuration mismatch. When you set a test for one modem of ASMi-52CQ, no
parameters for this modem can be changed, except to disable the specific test.
Once the line is disconnected, or one of the units is reset, the diagnostics stop.
In all diagnostics functions the clock mode remains unchanged, in order to avoid
interfering with the other channels.
