DS2000 Hardware Manual
Expanded Database
The Expanded Database is a new database method that provides database records (memory) for all
possible extensions, trunks, Hunt Groups, Ring Groups, and Voice Mail ports. This new capability
allows for:
Automatic Slot Configuration.
Simplified installation of Voice Mail, Hunt Groups, and Ring Groups.
Support for built-in UltraMail and IntraMail Voice Mail
Introduction of the DS-Series PC Program.
To understand the Expanded Database, you’ll need to keep track of three things: port, station (or
trunk) number, and extension number.
Port
The port is where the device you are programming connects to the system. For example, each
16DSTU PCB has 16 ports which can connect up to 16 digital telephones. Ports are numbered
consecutively for each slot, and only exist when you plug in the PCB to which the device
should connect.
Station Number and Trunk Number
The station or trunk number is the element in software that keeps track of the connected
devices’s programming. Station and trunk numbers (and associated database records) exist for
all possible devices you can connect to the system, even if you don’t have any ports installed
to connect them. You can’t call station and trunk numbers directly - you need the associated
extension numbers to do that (see below).
Extension Numbers
Extension numbers allow you to access the stations and trunks. By default, each station and
trunk number has an extension number assigned to it. You can change these assignments if
you want to.
- Digital station ports have primary and secondary station numbers. The primary station’s
extension number is used to call the device connected to the port. The secondary station’s
extension number calls the second channel on 2-channel devices such as 2-OPX Modules
and Digital VANGARD Voice Mail ports.
DS2000 Default Numbering
Here is how the ports, station numbers, trunk numbers, and extension numbers are initially set up.

To find out the default extension number for any station number,
add 299
to the station number.
- For example, station number
1
uses extension number
300
(1 + 299).

To find out the default extension number for a trunk number,
add 100
to the trunk number.
- For example, trunk number
1
uses extension number
101
(1 + 100).
