When setting up a PBX initially, the first step is to specify whether it is a NSX Server Unit or an Expansion
Gateway. If a PBX is specified as a Slave unit, it automatically locates the NSX Server Unit if they are on
the same LAN.

After the initial settings have been configured, the only additional step is to register the Expansion
Gateway to the The NSX Server Unit using a simple wizard. Note that an Expansion Gateway will not
function until it is registered.

Common extension numbering
All extensions are managed from the NSX Server Unit and behave as if they were all connected to one
PBX.
This feature is similar to common extension numbering over a TIE connection.

programming.

Trunk access
Extension users can access trunks at remote PBXs. Through system programming, outgoing calls can be
routed so as to reduce long-distance call charges.
•
Simplified programming
All PBXs in a Multi connection network can be programmed by logging in to the NSX Server Unit via Web
Maintenance Console. Both the global settings (settings that apply to all PBXs) and local settings
(settings that apply only to a single PBX) can be programmed without logging in to each PBX individually.
You can also log in to a Slave unit and program that PBX's local settings.
Restricting trunk access through COS settings
Trunk lines in a Multi-connection network are available to extensions at any site. While this feature may be
desirable in some cases (for example allowing extension users to access a local trunk from a distant
location to reduce call charges), COS settings can be used to reserve access to specified trunks for
extensions at a certain site. The following example shows how to allow only extensions 101, 102, and 103
access to trunks 1 and 2.
1.
In the trunk line settings, assign trunks 1 and 2 to a unique trunk group. (Trunk group 3, in this
example.)
