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:

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.

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:
