Installation Guide

1. Product Description

The Dialogic

D/480JCT-2T1-EW combined media

board provides up to 48 channels of voice and

media resources and two T1 telephony interfaces in

a single full-length PCI Express slot.

Additional Information

Additional information about the Dialogic

D/480JCT-2T1-EW board is available from a

number of sources.

The product data sheet, available at

http://www.dialogic.com/products, 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 Dialogic

D/480JCT-2T1-EW

board 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 Dialogic

D/480JCT-2T1-EW board

contains safety warnings and national

requirements for proper operation of

telecommunications equipment.

2. Before You Begin

Protecting the Board from Damage

CAUTION: All computer boards are sensitive to

electrostatic discharge (ESD). 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.

Part number: 64-0099-03

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

The Dialogic

D/480JCT-2T1-EW board uses Plug

and Play technology to simplify installation. No user

configuration is required for IRQ or memory

address.

The Dialogic

D/480JCT-2T1-EW board has three

manually configurable items:

Board ID

■

CT Bus termination

■

Remote loopback mode

■

Power budgeting (see Choosing a Slot section

■

below)

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, leaving

SW100 set to the 0 position (the factory default

setting) on all Dialogic

telecom boards causes

the system software to assign instance numbers

geographically, based on the bus and slot

numbers. Note that when using this method,

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.

As an alternative, you may set SW100 on each

board to a different position (0-9 or A-F) to

explicitly assign specific ID numbers to the

boards. Note that each board must be set to a

different ID number.

In either case, you can read the ID numbers

assigned to the boards in the Dialogic

Configuration Manager (DCM) after you start the

system and invoke that tool.

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 for Springware architecture products in

your Dialogic

System Software documentation

for further information about the board ID

numbers.

Setting the CT Bus Termination

Note: If you are using this product by itself and

not connecting it to other telephony boards via a

CT Bus cable, you do not need to set the CT Bus

termination jumpers.

Jumpers are used to terminate signals on the CT

Bus. These settings apply to boards located at

physical ends of the bus. For CT Bus or SCbus, the

signals CT_C8_A, CT_C8_B, CT_FRAME_A*, and

CT_FRAME_B* are terminated using pins 3 and 4 of

the P700 termination jumpers. For MVIP, C_2 and

C_4* are terminated using pins 1 and 2 of the P700

termination jumpers. Bus signals are terminated

when a jumper clip is installed over the indicated

pins.

Note: Only the two boards at each end of the CT

Bus ribbon cable must have their terminations

enabled. All other boards must not have the

jumper clips installed.

Setting Remote Loopback Mode

The Dialogic

D/480JCT-2T1-EW board is shipped

with SW500 and SW600 set for normal operation,

with the switch sliders in the position closer to the

board's bracket. Setting either switch to the

opposite position selects the loopback mode for the

corresponding network interface and overrides any

board modes set by your application. Loopback

mode is commonly used to check the network

connection after the firmware has been

downloaded to the board.

4. Choosing a Slot

The Dialogic

D/480JCT-2T1-EW 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 not support

this feature. Power Budgeting jumper P3 is

designed to ensure proper configuration of the

product.

The Dialogic

D/480JCT-2T1-EW board must be

installed in a slot that can be allocated 25W.

If Power Budgeting is not implemented by a

vendor's system, the Dialogic

D/480JCT-2T1-EW

board must be plugged into a x4 or higher slot

with the P3 jumper in position 1-2 (power

budgeting ignored). This is allowed per PCI Express

Card Electromechanical Specification Revision 1.0a

or higher because a x4 or greater slot must be able

to support a minimum of 25W.

If Power Budgeting is implemented by a vendor's

system, the Dialogic

D/480JCT-2T1-EW board

can be plugged into a x1 slot but the P3 jumper

must be in position pins 2-3 (power budgeting

adhered to).
