CHAPTER 6 OPERATION AND MAINTENANCE
• 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.
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.
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 communication system, the
corresponding system components have to be defined in the form of configurable objects (Managed
Objects: MO). These objects and the related event messages are stored in an object library referred to
as the Management Information Base (MIB).
You will find the interface description and the different MIB versions on Mitel InfoChannel – Mitel Solution
Alliance - API and Interface Information - MiVoice Office 400 - MiVoice Office 400 Network Management.
To access these documents, you have to be a member in Mitel Solution Alliance (MSA). If you are not a
member yet, go to Mitel website and search for “Mitel Solution Alliance” where you can join. A member-
ship on level MSA partner (MP) is sufficient.
5 SNMP destinations can be defined. Forwarding to the SNMP destinations can be activated and deacti-
vated independently of the forwarding to the local and external signal destinations.
NOTE: The SNMP destination is linked with the same event table as the local destination. Any changes to
the link and/or filter criteria for the linked event table also apply to the local destination.
