7.3 Operational Problems
The figure below shows how to pinpoint a failing piece of equipment or cabling by deduction from
local equipment and Interchange alarm relay indications, assuming that the ISDN network and
its diagnostic information are outside the control of the local management system.
Figure 43: Problem Determination.
Problems are detected initially by one or a combination of the following symptoms:
•
An alarm monitor detects that the alarm relay has triggered,
•
A user complaint,
•
An indication of Alarms from connected equipment, and or
•
Error status on the LED display.
If a fault is indicated in the InterChange iQ 2000 unit or the network beyond, you can
interrogate for the status of each port if management terminal access is available.
Otherwise, examine the status indications on the InterChange iQ 2000 or iQ 2000plus.
