The probe receives alarms events from Alcatel-Lucent ITM-SC workstations using the XMC interface.
The XMC interface is a software interface on Alcatel-Lucent ITM-SC workstations that allows communication with Netcool/OMNIbus. The XMC interface and the Probe for Alcatel-Lucent ITM-SC communicate through a TCP/IP connection.
The XMC interface provides for a unidirectional transfer of alarm data from the Alcatel-Lucent ITM-SC to the Probe for Alcatel-Lucent ITM-SC. When the probe logs in to the interface a session starts. All current active alarms in the Alcatel-Lucent ITM-SC are transferred to the probe by means of a synchronization procedure. Subsequent alarms are forwarded as they occur. Alarm and alarm-clears are supported.
A heartbeat message is sent by the Alcatel-Lucent ITM-SC to allow monitoring of the communication link. A session is terminated by (voluntarily or involuntarily) disconnection of the TCP/IP communication link.
Alarms are sent once, and are not re-transmitted. Re-transmission of alarms may occur because of synchronization after recovery from failure. Threshold Crossing Alert data (TCAs) are not forwarded through the XMC interface. The XMC interface provides no mechanisms to acknowledge alarms.
XMC Operational States
The Probe for Alcatel-Lucent ITM-SC operates in the following states:
The following sections describe the process sequence of the probe through each of the states. When the probe starts, it reads the rules and properties files, and then enters the Login state.
