Alarms
To display or print alarm messages, you can attach the DSU/CSU, either locally
or remotely, to an ASCII terminal or printer. Alarms can also be displayed on a PC
that is using a terminal emulation package.
You can route these alarms to the COM port or dial them out using an external
device.
Each alarm message contains a customer identification to indicate which remote
DSU/CSU is reporting an alarm. For information about customer identification,
refer to
Setting Customer Identification
in Chapter 3,

.
Possible alarm messages are as follows:

x
Interface (where
x
is either Network or DTE).
Alarm Cleared. Out Of Frame condition at the
