Dialogic D/41JCT-LS-EW Merkblatt

If the D/41JCT-LS-EW or VFX/41JCT-LS-EW will be 

connected to other telephony boards via a CT Bus 

cable, you should install the boards to minimize 

unused connectors on the CT Bus cable:

■

Install boards in adjacent slots whenever 

possible.

■

If the D/41JCT-LS-EW or VFX/41JCT-LS-EW 

board will be connected to one or more PCI 

boards, use the PCI Express slot(s) closest to the 

PCI slots.

CAUTION: To avoid possible damage to the board, 

remove power from the computer before beginning 

installation. Observe proper anti-static precautions 

at all times while handling and installing the board.

To install a D/41JCT-LS-EW or VFX/41JCT-LS-EW 

board, perform the following steps:
1. Turn off all power to the system and disconnect 

the system’s power cords.

2. Remove the computer’s cover.
3. Choose an empty PCI Express expansion slot 

and remove the slot’s retaining screw and 

access cover plate.

Note: If you are not installing the board in 

a full-length form-factor PCI Express slot, 

remove the slot retainer bracket from the 

end of the board before installation.

4. Insert the board’s edge connector into the bus 

slot, and apply firm pressure to the top edge of 

the board until the board is fully seated in the 

edge connector.

5. Reinstall the retaining screw.
6. Repeat steps 1 through 5 for any additional 

boards you are installing.

7. If applicable, connect the telephony boards 

together with a CT Bus cable of the appropriate 

size (not included). If possible, use a cable 

assembly that matches the number of boards in 

your system. If the cable has more than one 

unused connector, install the cable so that all 

the unused connectors are at one end of the 

cable.

8. Replace the computer’s cover.
9. Reconnect the computer’s power cord.

Each RJ-11 jack on the rear bracket of the 

D/41JCT-LS-EW and VFX/41JCT-LS-EW boards 

supports a single channel. Use RJ-11 connectors 

and telephone cable to connect each channel to an 

analog PBX or standard telephone outlet.
Note: Since these boards emulate a standard 

telephone, a standard telephone will not function 

when directly connected to the board.

Note: Connect the Earth Recall signal to pin 2. Do 

not connect Tip or Ring lines to pin 2, or improper 

operation of the D/41JCT-LS-EW or VFX/41JCT-LS-

EW will result.

The D/41JCT-LS-EW and VFX/41JCT-LS-EW boards 

require the use of an Dialogic

®

 System Software 

version that specifically supports it.

If this is the first Dialogic

 telecom board you have 

installed in your system, you will need to install an 

appropriate version of the Dialogic

®

 System 

Software and configure the software for the specific 

board(s) you are using. Refer to the installation 

and configuration documentation that accompanies 

the release for instructions.

If you are installing the board in a system that 

already has the Dialogic

®

 System Software 

installed, you should verify that your installed 

software version supports the board. If not, you 

will need to obtain and install a Service Update that 

does support the D/41JCT-LS-EW and VFX/41JCT-

LS-EW boards before configuring the system for 

the newly installed board(s).
Please refer to the Release Update document for 

your release version (on the Dialogic Telecom 

Support Resources web page) for up-to-date 

information about support for PCI Express boards 

and any known issues relating to their use.

Removal of the D/41JCT-LS-EW and VFX/41JCT-LS-

EW board is essentially the reverse of the 

installation procedure:
1. Observe anti-static precautions.
2. Disconnect the telephony cables.
3. Remove the computer’s power cord.
4. Remove the computer’s cover.
5. Disconnect the CT Bus cable (if applicable).
6. Remove and set aside the board’s retaining 

screw.

7. Remove the board and place it in static-

protective packaging.
