How Applications Fit into the Architecture
How Applications Fit into the Architecture
An application uses the control-and-inquiry interface to the X25AM subsystem by
sending requests (commands) to and receiving responses from SCP. An application
uses the Event Management System (EMS) to retrieve event messages generated by
the X25AM subsystem by sending commands to and receiving responses from an
EMS distributor process.
Commands an Application Can Issue
Table 2-1 lists and describes the commands that a management application can send
to the X25AM subsystem. These commands are described in detail in Section 6,
