MAS commissioning

To view installed packaged applications, use the Nortel MAS Console. The Nortel MAS Console lists the application version and the current operational state for that application. An example of a packaged application would be Recorder.

Configuration data

Each packaged application has one or more configuration parameters that you can modify to alter the behavior of the application. To view and modify these application-specific parameters, use the Nortel MAS Console.

Operational state

Each packaged application has an operational state that you can view and modify. To view and modify the operational state of an application, use the Nortel MAS Console.

You can select one of the following operational states:

•Unlocked—This is the default. Normal call processing is performed for the application.

•Locked—When the application enters a Locked state, existing sessions for that application are terminated and the system redirects new traffic. You typically place the application into a Locked state when performing maintenance (for example, application upgrades) to the application.

•Pending Lock—When the application enters a Pending Locked state, the system redirects new traffic for that application, while existing sessions are preserved.

MAS clusters

A MAS cluster is a collection of MAS nodes that work closely together. A MAS cluster shares the following resources:

•SNTP server for clock synchronization

•persistent content storage

•Controller Peer Ring

•redundant license servers

A cluster consists of N+1 active MAS servers where N is a maximum of 7 for high availability and redundancy. An additional server is used as a spare to accommodate one server failure. The spare server is active and handling traffic, but the entire system is engineered to N servers of capacity (not N+1). This ensures that enough remaining capacity is available to handle peak traffic if one server fails.

The following terminology describes the different cluster types:

•Duplex—a cluster consisting of two MAS nodes
