Identifying the Problem
This section describes how to identify problems, and
suggests possible solutions. Flow diagrams have been
used to summarize the process, and each step shown
in the flow diagrams is described in more detail in the
text.
This section assumes that the following conditions
have been met:
■
The ATM Module has been installed correctly, as
described in Chapter 6, “Installing and Setting Up
the Module”.
■
The device is “alive” when pinged, and can be
accessed through the local management screens.
■
Both the ATM Module and the ATM Switch or
attached ATM device are using the same physical
standard; either
SONET STS-3c or SDH STM-1 .
