Alarms
The DSU/CSU can be attached, either locally or remotely, to an ASCII terminal or
printer to display or print alarm messages. Alarms can also be displayed on a PC
that is using a terminal emulation package.
For standalone DSU/CSUs, you can route these alarms to the MODEM port, the
COM port, or both. For carrier-mounted DSU/CSUs, you can route them 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
Displaying Unit Identity
in Chapter 3,
Operation
.
