Figure 6-24   “Export” Dialog for Traffic Report Text File Saving
This Figure shows a sample image of the “Listup Report” window for the DTFD/DTFDN command. This window appears
by taking the following operations, and is used to obtain a sequence of Traffic data, so far collected and stored in the data-
base. The window is also used to save the Traffic data text (now displayed in the window) onto your desired PC directory.
- To activate this window:
1.  Designate a specific “Traffic Data” TYPE out of the DTFD/DTFDN command check boxes (see Figure 6-11-2).
2.  Press the “View Database” button on the left-bottom part of the DTFD/DTFDN command (see Figure 6-11-2).
Note
Note:  When thiswindow is activated, the initial text to appear is the newest file data, out of a sequence of Traffic reports.
             Like this, the newest text (in the database) appears on the first page, and the next new, the next page.

8.2.3 Service Conditions (when performing Traffic Measurement via TCP/IP)
(a) The NDM (network-level) data for the traffic measurement order is replaced/updated, at each time
the system is initialized or data change is requested from the ATRFN command.
(b) When the network-level data is once assigned via the ATRFN command, the node-level data for
ATRF command cannot be changed or modified.
(c) When the network-level data is once assigned via the ATRFN command, the already assigned data
by the ATRF command is not cleared, but becomes ineffective.
(d) When a data transfer error occurs, the following are performed in order:
Traffic measurement is suspended momentarily and system message is displayed (notification
of fault)
Traffic measurement, concerning all the remaining data except for the fault-involved one, is re-
sumed
Retry is made repeatedly for the transfer of fault-involved data, until the fault has been eradi-
cated
If the fault hasn’t been eradicated still until the time of next measurement routine, the data is
finally discarded, and next traffic measurement routine starts
(e) When the same Individual ATT Numbers exist on the network, the traffic measurement concerning
the ATTCON/DESKCON cannot be performed correctly.

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.
9.1 Office Data Stored Locations
The office data is stored in the Memory (MEM) and on the Hard Disk (HD). While the system is in ser-
vice, 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.
9.2 Office 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 (ASYD-SYS1, Index30, ASYDL-
SYS1, Index 513, 514).
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.

Service Conditions for MEM_HDD_N Command
This feature is made available by broadcasting the same back-up request signal toward all the nodes. If a failure
occurs in any of the process, the MEMHDD back-ups on a network level cannot be executed any more.
(Retry of signal broadcasting is not made.)
Service Conditions for HDD_MAT_N Command
When an error occurs in the process of data transfer, the updated program data is no more installed onto the
HDD of the node(s) which is/are involved in the fault.
9.4 Call Forwarding Data/Individual Speed Calling Data Management
Call Forwarding Data and Individual Speed Calling Data are changed at any time because these services
are set/cancelled from the station involved. In the PBX, these data are backed up by FD.
