The following principles govern the way event messages are signalled to an external
signal destination:
• Individual event messages are not signalled if they occur at short intervals. The
event messages are stored temporarily for 5 minutes and then sent together to the
external signal destination.
• If over a period of one hour an attempt is made unsuccessfully to send the event
messages to the external signal destination, the signalling period is extended from 5
minutes to 4 hours. As soon as the event messages are successfully output at the
external signal destination, the time period is reset to 5 minutes.
• If over a period of 1 hour an attempt is made unsuccessfully to send an event mes-
sage 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 un-
successful, 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 destina-
tion still available.
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 communica-
tion 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.
Notes:
– 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 destina-
tion still available.
