Dialogic TX4000 PCI SS7 Manual Do Utilizador

Before connecting a TX 4000 board to the network, ensure that you have properly 
configured the trunks as either T1 or E1. For configuration information, refer to the 
Dialogic® NaturalAccess™ Signaling Software Configuration Manual. 

Caution:  Dialogic obtains board-level approval certificates for supported countries. Some countries 

require that you obtain system-level approvals for boards connected to the public network. 
To learn what approvals you require, contact the appropriate regulatory authority in the 
target country. 

 

Use a shielded RJ-45 cable to connect a TX 4000 board to a T1 network or to an E1-
120 ohm network. Complete the following steps to connect a TX 4000 board to the 

network: 

1 

If connecting Trunk 1 or Trunk 2, connect a shielded RJ-45 cable directly to the board. 

If connecting Trunk 3 or Trunk 4, use dual T1/E1 120 ohm trunk adapter cables to connect to 
the board. Each trunk adapter cable divides the 8-pin modular jack on the end bracket into two 
RJ-48C connectors. If you are connecting both jacks, use two cables, otherwise, just use one. 

Note: TX 4000 boards are configured as T1/E1 120 ohm boards. To connect a TX 4000 board as 
an E1 75 ohm board, use a balun transformer to convert the impedance from 120 ohm to 75 
ohm. No other configuration changes are required. For more information, contact a Dialogic 
Services and Support representative. 

2 

Connect shielded RJ-45 cables directly to the trunk connector on the board or to the dual T1/E1 
trunk adapter cable. 

Failure to use a shielded cable may negate your approval.
