from 5 minutes to 4 hours. As soon as the event messages are successfully out-
put 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
message to an external signal destination, the number of dialling attempts is re-
duced 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
sage 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 sig-
nalled immediately to any signal destination 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 communi-
cation 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 sig-
nalled immediately to any signal destination still available.
SNMP destination
Depending on the event table allocated, event messages (normally Table 3) are
sent to a specified SNMP destinations.
