•
If no other PBXs are monitoring the selected extension, the monitored PBX stops transmitting status
information for that 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 a 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 at each monitor PBX.
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
•
KX-NSN002 (Activation Key for QSIG Network) is required for each Master unit that will monitor extensions
or have extensions monitored.
A separate activation key is required for non-KX-NS1000 PBXs. For details, refer to the corresponding
Feature Guide.
•
NDSS buttons will not function on networks using Common Extension Numbering for 2 PBXs, or Common
Extension Numbering for Multiple PBXs.
•
All PBXs in the network must be KX-NS1000 PBXs, or KX-NCP series, KX-TDE series, or KX-TDA series
PBXs. For information on the hardware requirements for non-KX-NS1000 PBXs that will monitor extensions
or have extensions monitored, refer to the corresponding Feature Guide.
•
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.

•
Extensions connected to one PBX can monitor a maximum of 250 extensions at other PBXs. One extension
can be monitored by multiple extensions at multiple PBXs.
•
To reduce NDSS data traffic, it is recommended that 8 or less extensions in a single Incoming Call
Distribution Group be monitored.
•
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.

•
A maximum of two ports of each BRI card can be assigned to transmit extension status information
("ON").
•
Through system programming, it is possible to assign a maximum number of "hops" (transfers between
PBXs) that extension status information can travel. Each time a piece of extension status information is
forwarded to another PBX, its counter is increased by one. When this counter reaches the assigned
maximum, the data is discarded. This is used to prevent data from circling unnecessarily around the
network.
