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
destination missing.
Note:
Event tables and signal destinations should be set in such a way that the event message
External event message destination missing
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
tion still available.
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).
If the Network Management System is to know the potential events of the communica-
tion system, the corresponding system components have to be defined in the form of
