13.1.15Private Network Features—NDSS (Network Direct Station Selection)

Description

When PBXs are networked using ISDN or IP-GW cards, it is possible to assign flexible buttons as Network Direct Station Selection (NDSS) buttons. These buttons are used to monitor the status of extensions connected to up to seven other PBXs in the network, and to make or transfer calls to those extensions with one touch, like normal DSS buttons. This allows operator functions to be centralized even when there are offices in remote locations.

NDSS buttons show the status of the monitored extension as follows:

Light pattern

Off

Red on

Status

The monitored extension is idle.

The monitored extension is busy or has set DND for CO line calls.

[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 (13.1.13 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.
