WARNING! Installing the Dialogic
®
D/480JCT-2T1-EW board in a x1 slot with the 
P3 jumper in position 1-2 will void the 
warranty of the D/480JCT-2T1-EW board.
If the Dialogic
®
 D/480JCT-2T1-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 (in addition 
to ensuring that the power requirements are met):
■
Install boards in adjacent slots whenever 
possible.
■
If the Dialogic
®
 D/480JCT-2T1-EW board will be 
connected to one or more PCI boards, use the 
PCI Express slot(s) closest to the PCI slots. 
5. Installing the Board
WARNING! Unplug the equipment before 
performing the procedures described here. 
Failure to disconnect the power before you 
open the chassis can result in personal injury. 
Ensure that the system is disconnected from 
its power source and from all 
telecommunications links, networks, or 
modem lines whenever the chassis cover is 
removed. Do not operate the system with the 
cover removed.
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 the Dialogic
®
 D/480JCT-2T1-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.
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. 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.

6. Connecting to External 
Equipment
Each RJ-48C jack on the rear bracket of the 
Dialogic
®
 D/480JCT-2T1-EW board supports a 
single T1 digital network interface. Use appropriate 
cables to connect the RJ-48C jacks on the bracket 
to your CSU or other network termination 
equipment. The bottom RJ-48C connector is for 
span 1, the top connector is for span 2.
The following figure illustrates the pinout of the 
RJ-48C jacks. 
7. After Installing the Board
If you are installing the Dialogic
®
D/480JCT-2T1-EW in a system that already has the 
Dialogic system software installed, you may not 
need to install a new or upgraded software release 
to support the board. The Dialogic
®
D/480JCT-2T1-EW has been designed to be 
compatible with existing System Release 6.x 
software versions that support PCI boards. Please 
refer to the Release Update document for your 
release version for up-to-date information about 
support for PCI Express boards and any known 
issues relating to their use.
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. 
When configuring the system for the Dialogic
®
D/480JCT-2T1-EW board, use the same menu 
selections and configuration settings that are 
documented for the PCI version of the 
D/480JCT-2T1 board.
