CHAPTER 6 OPERATION AND MAINTENANCE
In this example an event message is sent to the message destinations if there is a Total synchronization
loss event message when the system generates the event message 10 times within 1 hour.
Signal destinations
After a first start, all event tables are exactly assigned to a message destination. (Exception: Local desti-
nation and SNMP destination use this event table.) You can assign event tables to several or no message
destinations
The destinations are configured in the Message destinations ( =h1) view.
Signal destination system phone 1 and 2
Event messages are sent to all system phones with display and entered in the corresponding message
group.
• Destination system phone 1:
– By default allocated to event table 1, which is preconfigured for common use.
– Fix allocated to message group 16.
• Destination system phone 2:
– By default allocated to event table 8, which is preconfigured for front desk terminals in hospi-
tality environments.
– Fix allocated to message group 15.
External signal destinations
Depending on the event table allocated, event messages (normally Table 2) are sent to a specified
external signal destination. Two external signal destinations can be specified:
• 1 primary external signal destination
• 1 alternative external signal destination
If the system issues an event message, the event message opens a PPP communication channel from
the public network of the communication server to a terminal adapter or modem. Once the event message
has been confirmed, the system clears down the PPP connection.
