Operation and Maintenance
• If over a period of 1 hour an attempt is made unsuccessfully to send an event message to an external
signal destination, the number of dialling attempts is reduced from 5 to 2. As soon as an event message
has been successfully sent, the number of dialling attempts is increased to 5 again.
• If the attempt to send an event message to an external signal destination was unsuccessful, the system
will generate the event message External event message destination missing.
Note:
Event tables and signal destinations should be set in such a way that the event message External
event message destination missing is signalled immediately to any signal destination still available.
6.5.1.3.3 Local signal destinations
Depending on the event table allocated, event messages (normally Table 3) are sent to a specified local
signal destination.
PPP links:
Like with an external signal destination the event message opens a PPP communication channel from the
communication server to a terminal adapter or modem. Once the event has been confirmed, the system
clears down the PPP connection.
Ethernet link:
A PC connected either directly to the Ethernet interface or to the communication server via a LAN can be
configured as the local signal destination.
Note:
• The local destination is linked with the same event table as the SNMP destination. Any changes to
the link and/or filter criteria for the linked event table also apply to the SNMP destination.
• Event tables and signal destinations should be set in such a way that the event message External
event message destination missing is signalled immediately to any signal destination still available.
6.5.1.3.3.1 SNMP destination
Depending on the event table allocated, event messages (normally Table 3) are sent to a specified SNMP
destinations.
SNMP stands for "Simple Network Management Protocol" and is used by Network Management Systems
(NMS).
