7 Event Management
The X25AM subsystem provides information about events that it detects by issuing
event messages. A management application can obtain these event messages by
opening an Event Management System (EMS) distributor process and requesting the
messages. The application can also specify that a filter be applied to select certain
event messages. This section describes the event messages that the X25AM
subsystem can issue and the specific programming considerations for dealing with
X25AM event messages in an application. For general information on how an
application obtains event messages from a subsystem, see the EMS Manual.
In this section, event-message tokens and their values are represented in DDL. For a
quick explanation of DDL as it applies to SPI, refer to the appendix "Summary of DDL
for SPI" in the SPI Programming Manual.
This section contain these topics:
Subsystem Processes that Report Events
Event messages issued by the X25AM subsystem are generated by the X25AM line-
handler processes. All event messages issued by the X25AM subsystem contain the
X25AM subsystem ID, which is described in Section 5, Common Definitions. For more
information about subsystem IDs, see the SPI Programming Manual.
