All Implemented Interfaces:

Runnable, Observer, TreeNode

public class DialogChannelStatusBean
extends SNMPRunBean
implements Observer, TreeNode

This bean is written for a Dialogic card. The Dialogic MIBs come with their BoardWatch package. You will have to fill in a form before downloading it.

This bean collects information about the voice channel status of the Dialogic card. It will only collect those channels that are open.

You can get the data via the getChannelIndexes() and getChannelStatus(Integer index) methods. This way you can visualise the data yourself.

You can also use the Swing JTree to visualise the channels. This bean implements the Swing TreeNode interface. The user has to set the setDefaultTreeModel, so this class can update all the nodes that are added, removed of changed. If this class is not the root of the JTree, you have to set the (TreeNode) parent of this class.

The properties in the parent classes should be set, before calling the action() method. Via a TreeModelEvent the application/applet will be notified.

We only have one (1) Dialogics card, so I don't know how and if it works with more than 1 card. Please let us know if it doesn't work.
