Figure 4-3: Monitoring system interface of a typical module
The monitoring system enables you to monitor traffic passing through a
module. To do so, test equipment is connected to the monitoring point of the
corresponding module, and the module and port are selected by the system's
selectors. As a result, the traffic is closed through the test equipment and the
signal can be viewed, in an eye pattern, on the test equipment display.
Selecting a module
The MODULE selector chooses the monitored module slot number. The
selected module is displayed on the 2-digit display to the right of the selector.
Pressing the selector upward increments the slot number; pressing it downward
decrements the slot number. The selection is cyclic. Possible selections are QA
(I17) and QB (I18) for the aggregate cards (I/O cards), and I1 to I16 for the I/O
modules. If the selected module is an STM-1, the MON indicator on the
ECU300-F lights.
