TX 4000 PCI SS7 Network Interface Board Installation Manual Establishing network connections
Connecting to the network
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:
Step Action
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.
Caution: Failure to use a shielded cable may negate your approval.
The following illustration shows the cabling required to connect all four trunks on the
TX 4000 board:
