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

The Computer Telephony bus (CT Bus) provides communication and flexible resource sharing among the boards connected to the bus. The D/ 41JCT-LS-EW and VFX/41JCT-LS-EW boards have a

1. Product Description

The Dialogic® D/41JCT-LS-EW and VFX/41JCT-LS- EW boards are combined media analog boards with H.100 connectivity and four ports of voice, fax, and

setting of SW30 controls the generation of the instance numbers.

Windows Systems: In a Windows system, leaving SW30 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 SW30 on each board to a different position (0-9 or A-F) to explicitly assign specific ID numbers to the

CT Bus connector that complies with the ECTF H.100 specification, and as such can be connected to the CT Bus with a CT Bus cable. To connect the boards to the CT Bus, set the CT Bus jumpers according to instructions in this section.

If you do not require media sharing or switching across the CT Bus, you may use the D/41JCT-LS- EW or VFX/41JCT-LS-EWby itself with no CT Bus cable. If you are not using a CT Bus connection, you do not need to set the CT Bus jumpers and you can proceed to Section 4, Choosing a Slot.”

Note: If you are operating the board without a CT Bus connection, you must configure the board to H.100 bus mode. Otherwise, all attempts to download to the board will fail because the CT Bus clock is absent.

speech in a full-length PCI Express form factor. The D/41JCT-LS-EW board supports basic fax, while the VFX/41JCT-LS-EW board supports enhanced fax.

The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards include the following components:

J1-J4 jacks: Four RJ-11 jacks to connect to PBX or telephone network (Central Office) lines.

SW30: Rotary switch used when setting board ID.

SW4: Slide switch used to set hook state at startup.

CT Bus connector: H.100 telephony bus connector.

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 SW30 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

The following instructions apply only to the boards at each end of the CT Bus cable. Boards that are in the middle of the CT Bus cable should not be terminated.

Note: If these boards are operating in SCbus mode, CT Bus (H.100) termination is not required.

JP1 jumper is reserved and unused. Do not install a jumper link across the pins of JP1.

JP2 is a 2-pin jumper that is used to terminate the CT Bus, ensuring that proper electrical characteristics exist on the CT Bus. By factory default, this jumper is not terminated on the board.

JP2 jumper: CT Bus termination jumper.

JP1 jumper: Not used.

PCI Express connector: Host bus connector. Compatible with x1 or larger PCI Express Link connectors.

Additional Information

Additional information about the D/41JCT-LS-EW and VFX/41JCT-LS-EW boards 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 D/41JCT-LS-EW and VFX/41JCT- LS-EW are 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 D/41JCT-LS-EW and VFX/41JCT-LS-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://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 anti-static packaging. 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 D/41JCT-LS-EW and VFX/41JCT-LS-EW boards use Plug and Play technology to simplify installation. No user configuration is required for IRQ or memory address.

The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards have the following manually configurable options:

■Board ID

■Initial hook state

■CT Bus termination

numbers.

Setting the Initial Hook State

The position of slide switch SW4 determines how the board responds to an incoming call when the chassis power is on but the board is not initialized. Set the SW4 slide switch as follows:

■SW4 = off (default): Callers hear ringing (on- hook).

			SW4
	Ringing (On-Hook)
			OFF

■SW4 = on: Callers hear a busy signal (off-hook).

Busy (Off-Hook)		SW4

		ON

Note: If the chassis power is off, callers hear ringing (on-hook) regardless of the setting of SW4.

To use the CT Bus:

■Install a jumper link on the JP2 jumper of a board to terminate the CT Bus at that board.

■Only terminate the first and last boards (the boards located at each end) on the CT Bus cable.

■Do not install a jumper link across the pins of JP2 on boards located between the end boards on the CT Bus cable (the jumper link must be disconnected on the JP2 jumper to disable termination).

The JP2 jumper terminates the following H.100 signals: CT_FRAME_(A&B) and CT_C8_(A&B).

4. Choosing a Slot

The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards implement a PCI Express x1 lane configuration, allowing them to be used in any full-length PCI Express slot that fully meets PCI Express Card Electromechanical Specification Revision 1.0a or higher.

If the D/41JCT-LS-EW or VFX/41JCT-LS-EW is the only Dialogic® telecom board in the system, you may choose any slot for the installation.
