1. Product Description

The Dialogic

®

 DISI switching boards are full-size, 

single-slot PCI Express boards. They provide 

connectivity for up to 16, 24, or 32 station interfaces 

and include conferencing, voice play/record, tone 

detection and generation, and Caller ID capabilities.

Additional Information

Additional information about the DISI is available 

from a number of sources.
The product data sheet, available at http://

www.dialogic.com/products/list.asp, provides a 

functional description as well as information about 

applications and configurations, features, and 

technical specifications.
Refer to the Release Guide and the online Release 

Update for your Dialogic system software release to 

verify that the DISI is supported in the release and 

for information on any new features or issues that 

may relate to it.
The Regulatory Notices document that is packed with 

each DISI board contains safety warnings and 

national requirements for proper operation of 

telecommunications equipment.

WARNING! This analog station interface 

product is designed to be used only within the 

walls of a single stand-alone building or 

structure (i.e., on-premise). It is not designed 

to sustain electrical overstress from external 

sources and factors such as severe weather 

conditions. Severe electrical overstress caused 

by misuse of this interface product with cables 

extending outside of the walls of a single stand-

alone building or structure could cause property 

damage and/or personal injury and/or death. 

Such misuse voids the warranty for this 

interface product.

2. Before You Begin

Protecting the Board from Damage

CAUTION:

All computer boards are sensitive to 

electrostatic discharge. Handle all static-sensitive 

boards and components at a static-safe work area, 

and observe anti-static precautions at all times.

If you are not familiar with ESD safety precautions, 

visit http://www.dialogic.com/support/hwinstall to 

learn more.

Unpacking the Board

Unpack the board according to the following steps:
1. Prepare a static-safeguarded work area. 

2. Carefully remove the board from the shipping 

carton and static-shielding bag. Handle the board 

by the edges and avoid touching the board's 

components.

3. Lay the board on the static-dissipative work 

surface.

Note:

Place boards in static-shielding bags when 

carrying boards from station to station.

CAUTION:

Do not remove the board from the anti-

static packaging until you are ready to install it. 

Observe proper anti-static precautions at all times.

3. Configuring the Board

Setting the Board ID

When the system is started, each Dialogic telecom 

board is assigned a board instance ID number that 

programs can use to identify individual boards in a 

multi-board system. The setting of SW100 controls 

the generation of the instance numbers.

Windows* Systems: 

In a Windows system, leave 

SW100 set to the 0 position (the factory default 

setting) on all Dialogic telecom boards. This setting 

causes the system software to assign instance 

numbers geographically, based on the bus and slot 

numbers. Note that there is no way to know what 

the instance numbers will be until the system is 

started and configured, and the instance number 

for any given board is likely to change when there 

is any change in the number or arrangement of 

boards in the system.
You can read the ID numbers assigned to the 

boards in the Configuration Manager tool after you 

start the system.

Linux* Systems: 

In a Linux system, you must 

explicitly specify the board ID numbers by setting 

SW100 on each board to a different position (0-9 

or A-F). Refer to the Configuration Guide in your 

System Software documentation for further 

information about the board ID numbers.

4. Choosing a Slot

The DISI board is a full length x1 form factor PCI 

Express board that requires 25W of power. The 

following explanation and guidelines are provided to 

ensure proper configuration of the product.
Power Budgeting is a new feature, introduced in the 

PCI Express Specification, that provides a mechanism 

to enable a system to negotiate power consumption 

requirements for add-in devices.
Per PCI Express Card Electromechanical Specification 

Revision 1.0a or higher, a x1 add-in card can draw no 

more than 10W in a x1 slot unless the board’s 

required power is successfully negotiated and 

allocated by the system (power budgeting). However, 

implementation of power budgeting by a vendor's 

system is not a compliance requirement per the PCI 

Express Card Electromechanical Specification 

Revision 1.0a or higher. Therefore, some chassis may
