Troubleshooting and
Diagnostics
This chapter describes the ASMi-52CD diagnostic functions, which include:
• Diagnostic tests:
 Loopback tests for ASMi-52CD/4 with synchronous and E1 interfaces
 LED test
• Status indications and alarms
• SHDSL performance diagnostics
• Troubleshooting procedures.
5.1 Introduction
ASMi-52CD offers diagnostics for troubleshooting:
• Loopback – Tests the performance of the local modem and either the remote
modem or the local DTE, and the lines connecting them. (Serial interfaces
only.)
• Alarm buffer – Contains alarm messages regarding the status of the
transmission system
• SHDSL statistics collection
All diagnostics options can be performed using RADview SNMP management tool
or an ASCII terminal. Then, examine the alarm buffer messages for any
transmission error or configuration mismatch. When you set a test for one
modem of ASMi-52CD, 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.
For ASMi-52CD/4 with E1 interface in all diagnostics functions the clock mode
remains unchanged in order to avoid interfering with the other channels.
