• 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.

• 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.

• 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.
→ 2.10.8 [4-1-6] Wired Extension—NDSS Link Data - Send
→ 2.10.15 [4-2-4] Portable Station—NDSS Link Data - Send
• When using a VoIP network, 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.
• NDSS can not be used when two PBXs are networked using the TIE Line Call by Own PBX Extension
Number feature (→ 1.13.13 PRIVATE NETWORK FEATURES).
