This manual is for system software versions 03.**.** or higher.
Software version 03.**.** requires expanded memory
CPU P/N 80025B. Do not install in prior versions.
Expanded Database
System numbering is expanded in version 03.**.**. See Expanded Database on page 1-
2 for more.
• Extension numbers are 300-427 and trunk numbers are 1-64 (using extension numbers
101-164).
• UCD Hunting Groups are preset at 700-707, and the Voice Mail Hunt Group is preset
at 700.
• Ring Groups are preset at 600-607.
Automatic Slot Configuration
Automatic Slot Configuration automatically sets up station and trunk PCBs when you
initially power up the system. This simplifies installation because you no longer have to
use system programming to activate station and trunk PCBs after you plug them in.
• See Automatic Slot Configuration on page 1-4 for more.
Simplified Voice Mail Programming
The system provides a predefined set of Voice Mail station numbers (201-208), which
have a predefined set of correspondingVoice Mail extension numbers (500-507). In addi-
tion, the Voice Mail extension numbers are already designated asVoice Mail ports and
assigned to a predefined UCD Hunting Group (with 700 as the master number). Because
of these assignments, programming external Voice Mail is a simple, 2-step process:
• In Program 8001 - Voice Mail Setup , enter E to enable externalVoice Mail. (IntraMail
and UltraMail set up this option automatically.)
• In Program 9902 - Set Up Stations (DS2000) , assign the Voice Mail ports to the pre-
defined Voice Mail station numbers (201-208).
• See Voice Mail Setup in the Quick Setup Guide that came with your system for more.

Unpacking
Unpack the equipment and check it against your equipment lists. Inspect for physical damage. If you are not
sure about a component’s function, review the Product Description Manual. Contact your Sales Representa-
tive if you have additional questions.
Have the appropriate tools for the job on hand, including: a test set, a punch down tool and a digital voltmeter.
Before Installing
Make sure you have a building plan showing the location of the common equipment, extensions, the telco
demarcation and earth ground. In addition, the installation site must meet the requirements outlined in the
Standard Practices Manual.
Site Requirements
The common equipment is contained in the wall-mounted Main Equipment Cabinet. Choose a central location
for the cabinet that allows enough space for the equipment — and provides enough room for you to comfortably
work. Figure 1-1 4 Slot Cabinet Installation Layout on page 1-8 and Figure 1-2 8 Slot Cabinet Installation
Layout on page 1-9 show you about how much space your system requires.

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 IntraMailVoice 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.
Default Numbering in DS2000

32 97-128 396-427
Total Station Ports 128 --
• 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).
Trunks Ports Trunk Numbers Extension Numbers
Trunk Ports Set by installed PCB 1-64 101-164
Total Trunk Ports 64 --
• 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).

The following table shows the port capacity of each DS2000 PCB.
Since the Expanded Database maintains database records for all extensions and trunks, you have
the option of using Program 9902 - Set Up Stations (DS2000) and Program 9903 - Set Up
Trunks (DS2000) to assign a station and a trunk PCB to the same slot . When you plug in an ASTU
or DSTU PCB into the slot, the ports on the PCB access the associated station numbers. If you
remove that PCB and plug an ATRU in its place, the ports on theATRU PCB access the associated
trunk numbers. Refer to the Software Manual on the System Document CD that came with your sys-
tem for more.

System Preparation and Configuration

Automatic Slot Configuration
Automatic Slot Configuration automatically sets up station and trunk PCBs when you initially
power up the system. This simplifies installation because you no longer have to use system pro-
gramming to activate station and trunk PCBs after you plug them in.
Here’s how Automatic Slot Configuration works:
●With power off, install your station and trunk PCBs.
With the system powered down, install the station and trunk PCBs from left to right in the
order you want your extension and trunk numbers set up.
-Be sure to install a 16DSTU (16 Digital Station) PCB in the first slot (CN1).
- You don’t have to group your station and trunk PCBs together, although it may be more
convenient to do so. For example, when setting up a 16x32 system, you can install the 2nd
DSTU PCB and your two ATRU PCBs in any slot, in any order. Automatic Slot Configura-
tion will properly handle the numbering.
●Power up the system.
On power up, the system scans the PCBs from left to right and sets up the extension and trunk
numbering as follows.
- Extension numbers will begin with 300 in the first slot and increment from left to right.
- Trunk numbers will begin with 101 (starting from the first installed ATRU PCB) and will
also increment from left to right.
- For example, in a 16x32, the numbering will be:
1st 16DSTU PCB = Extensions 300-315.
2nd 16DSTU PCB = Extensions 316-331.
1st 8ATRU PCB = Trunks 101-108.
2nd 8ATRU PCB = Trunks 109-116.
System Configuration
DS2000 Default Configuration
Automatic Slot Configuration automatically sets up your system’s PCBs when you initially power up the sys-
tem. There is no longer a factory-installed default configuration, and you don’t have to use system programming
to activate PCBs after you plug them in. Remember, you should always plug a 16DSTU PCB into slot CN1.
To take full advantage of all the new features and enhancements in software version 03.**.**, always use the
latest PCB versions.

DS2000 Configuration Guidelines
The total number of components you can install and connect depends on power supply capacity and the Sys-
tem Load Factor. Review the DS2000 Configuration Guidelines table below and DS2000 Load Factor Cal-
culations on page 1-6 when configuring your system.
DS2000 Configuration Guidelines

DS2000 Load Factor Calculations
The combination of trunks, extensions, 2-OPX Modules and DSS Consoles you can connect to your DS2000
system may be limited by the System Load Factor. Use the DS2000 System Load Factor Calculations chart
on the next page to verify your system’s configuration. When entering data on the chart, for each installed
item make entries for each Load Type. There are two Load Types to consider: 5 VDC and 40 VDC.
To check your system configuration:
1. Indicate the quantity for each PCB, DSS Console, and 2-OPX Module installed in the Qty column.
The number of keysets and single line sets does not affect the System Load Factor.
2. For each item for each Load Type, multiply the Qty times the Load and enter the value in theTotal
column.
For example, two 16DSTU PCBs have a load of 6 for 5 VDC and 40 for 40 VDC.
3. Add up the entries in eachTotal column and enter the values in Item 1: Load Type Totals.
4. Review Item 2: Power Supply Capacity and determine the capacity of the power supplies installed
in your system.
5. Compare the capacities in Item 2to your entries in Item 1. Item 1must always be equal to or less than
the entry in Item 2.
!! Important !!
Do not operate your system if the total for either Load Type
exceeds the Power Supply Capacity of your installation.

Installing the Cabinet
Planning the Installation
Before installing the common equipment, you should mount a Main Distribution Frame (MDF) plywood back-
board in a centrally located spot. A 1/2 sheet of plywood (4’ x 4’) should be adequate for a 4 slot cabinet (see
Figure 1-1 4 Slot Cabinet Installation Layout below).A full sheet of plywood (8’x 4’) should be adequate for
an 8 slot cabinet (see Figure 1-2 8 Slot Cabinet Installation Layout on page 1-9 ). Be sure to mount the back-
board using suitable fasteners, taking care to adhere to standard installation practices and local codes.
The equipment cabinet requires a three-prong, dedicated 110 VAC 60 Hz circuit (NEMA 5-15 receptacle).
The AC receptacle must be within 7 feet of the cabinet’s lower left corner.
Normally, you install the extension and trunk blocks to the right of the cabinet. Telco should also install the
RJ21X to the right of the cabinet.
!! Important !!
Local codes may prohibit you from installing extensions,
trunks and optional equipment in the same blocks.

Removing the Right Side Panel
Remove the cabinet right side panel to gain easy access to the ground lugs and system cabling. The cabinet
has two ground connections: ETH (Earth Ground) and PBXG (PBX Ground).
To remove the right side panel (Figure 1-8):
1. Remove the two screws that secure the right side panel to the cabinet.
2. Carefully slide the right side panel down until it swings clear of the cabinet.
Attaching the Ground Wires
The system provides two ground terminations. Each ground connects from the system to the ground termina-
tion using 12 AWG stranded copper wire.
● Use the ETH (Earth Ground) for safety/system ground.You must connect ETH to a known earth ground.
● Use the PBXG (PBX Ground) if you have trunks that require telco ground (such as ground start trunks).
This ground is not required for loop start trunks.
