9.OFFICE DATA MANAGEMENT

This section explains how to manage various kinds of data such as Call Forwarding Data, Individual Speed Calling Data, and Office Data, etc.

9.1Office Data Stored Locations

The office data is stored in the memory (MEM) and on the Hard Disk (HD). While the system is in service, it operates by the office data stored in the memory. Should the contents of the office data be destroyed due to trouble, the system restarts its operations by loading the office data from the hard disk into the memory. The office data of the system in operation is being backed up by the hard disk.

9.2Office Data Preservation

Since the PBX keeps operating by the assigned office data, be sure to preserve the latest office data. If the office data is not preserved, all office data must be reassigned if the contents of the data memory have been destroyed, because of trouble occurrence, etc. The system will remain in a system down state until reas- signment of the office data is complete.

Practice to verify and confirm the valid office data by routine maintenance is considered an effective means to prevent loss of the office data and occurrence of trouble due to the office data. For this reason, be sure to keep the following items near the system at all times so that they may be available when needed.

(1)Office Data Programming Sheets

As the most up-to-date data must be recorded in the sheets, be sure to make entries by pencil.

(2)Floppy Disks for Data Saving

To back up the office data stored on the HD, use floppy disks. The necessary number of Floppy Disks (FD) is determined by the following factors:

•Mounting capacity of office data depends upon the system data (SYS1, Index30).

•Each floppy disk can save 1MB of data. After a large-scale office data change, in particular which includes system data, unpredictable failures might occur. To deal with such failures, prepare an FD for saving the office data before the changing. In addition, prepare an FD for saving the latest office data.
