of that extension, and the monitor PBX will begin to receive the information. The button light will display
the status of the extension connected to another PBX.
Removing or Editing a Registered Extension [Monitor PBX]
To monitor a new extension when 32 extensions are already being monitored, it is necessary to remove the
registration of an existing extension.
The NDSS Monitor Release feature is used to stop monitoring a certain extension. When this feature is
performed at the monitor PBX:
• The monitored PBX stops transmitting status information for the selected extension.
• The monitor PBX stops receiving status information for the selected extension. All NDSS buttons
for that extension stop displaying status information.
However, the related information is not deleted from the Network Monitor Extensions Table. Therefore, if an
extension user at the monitor PBX subsequently goes off-hook and presses the NDSS button for that
extension, monitoring will be reactivated. To completely remove monitoring of an extension, the registration
data must also be deleted from the Network Monitor Extensions Table.
The monitor destination of each NDSS button is determined by the registration information for a particular
index number in this table. Therefore, if the registration information for an index number is changed (for
example, the Network Extension Number assigned to Index No. 001 in the example above is changed from
"2001" to "4002"), any NDSS buttons that have been set for that extension will automatically point to the
new monitor destination.
Conditions
• Hardware Requirements:
All PBXs in the network must be KX-TDA series MPR version 2.0 or greater.
If using an IP-GW4E card (KX-TDA5480), the firmware (not LPR) of the card must be version 1.2 or
greater.
• Each of Network PBX IDs 1-8 can only be assigned to one PBX within a network. Assigning the same
Network PBX ID to two PBXs will cause network data transmission problems.
• It is only possible to assign NDSS buttons for extensions that have been previously registered in the
Network Monitor Extensions Table.
• Activation of an NDSS button is only required the first time that a button for a newly registered extension
is created. Once an NDSS button has been activated by being pressed the first time, any further NDSS
buttons for the same monitored extension will automatically display the extension status without
needing to be activated.
• To use the NDSS Monitor Release feature, an extension must be assigned as a manager (
→
Manager
Assignment [511]).
• If it is not possible to remotely turn off transmission of extension status information using the NDSS
Monitor Release feature because of network conditions, it is possible to perform the same operation
directly through system programming at the monitored PBX.
• If extension status information is lost by the network, in some cases an NDSS button may not be able
to display the status of the relevant extension.
