[Programming Procedure]
1. Routing Table Assignment
TIE Line Routing and Modification tables must have been programmed in advance for all PBXs in the
network, to allow calls to be made and transferred between PBXs (® 13.1.15 PRIVATE NETWORK
FEATURES).
In
the programming example that follows, the PBXs in the network use the Extension Number method, as
shown in the illustration above. However, the PBX Access Code method can also be used.
2. Network PBX ID Assignment
Assign a Network PBX ID to each PBX in the network.
® 11.2 [9-2] Network Data Transmission—
Network Data Transmission for Centralized Operator
Feature—Network PBX ID
• IDs 1-8: Can monitor
extensions at other PBXs, and transmit monitor data about local extensions. Each
ID number can be assigned to one PBX within the network.
• ID 0: Retransmits monitor data throughout the network. This ID number can be assigned to multiple
PBXs.
3. QSIG Port Setting [Monitored PBX]
ISDN-QSIG (PBX Direct Connection)
Each QSIG port of a PRI card that will be used to transmit extension status information must be set to do
so through system programming. Even if a port is set to not transmit information, it will still receive
information from other PBXs.

Networking Data Transfer
Transmit Extension Status Information Functions
Enabled
• Transmit information on own PBX extensions
• Receive information from other PBXs; forward it to other QSIG ports of
the PBX
• Re-transmit information received by other QSIG ports of the PBX
Disabled
• Receive
information from other
PBXs; forward it to other QSIG ports of
the PBX
Set the transmission setting for each port according to the layout of your network, so that extension status
information can travel between NDSS monitor PBXs.
