4.15.3 Cause Mapping Tables

Use the Cause Mapping Tables to specify changes in selected causes. By assigning causes to different types of virtual ports you can present identical causes in a different way on the system interfaces. To assign a mapping table to a virtual port use the Basic tag for the particular virtual port. You can also specify in which direction the mapping table should be used. One and the same table can be used for different interfaces and both directions at the same time. Hence, an internal caue can be translated into a cause towards the SIP interface and also in the opposite direction.

The menu has two sections. You can add, remove and rename mapping tables to the left. The right-hand section includes two parameters and the mapping table.

• Name – name of the selected mapping table.

• Mask stack cause – disable displaying of the original cause in the system trace for the whole mapping table. In that case, the trace displays Type: None. 

Mapping Table

The context menu helps you add, remove and remove all rows of the table. The table consists of twelve columns and an unlimited number of rows. The sequence of rows is irrelevant unless there are two rows with an identical cause and different settings. In that case, the earlier-added row is applied (the one higher in the configuration).

• Cause – choose one of the pre-defined system causes. Here user causes are applied.
• Mask – disable displaying of the original cause in the system trace for a selected mapping table row.
• SIP value – choose one of the available causes for the given row.

• Valid – enable translation for an SIP stack.
