Installation of Announcement Machine

The standard announcement machine available is PA-4DATA or PA-4DATB (4DAT: 4 Digital Announcement Trunk) card. The 4DAT can be used by simply inserting it in the universal slot of PIM.

If a non-standard announcement machine is used, the connection method and the announcement trunk to be used as interface vary depending on the machine.

An example of this connection is shown in Figure 3-13.
