TX 4000 PCI SS7 Network Interface Board Installation Manual  
Establishing network connections 
Single-node redundant signaling server 
The following illustration shows how to set up two TX 4000 boards based on the 
single-node signaling server in a TDM configuration. The boards are located in the 
same chassis to ensure board-level redundancy.

IP network configuration 
To connect a TX 4000 board to its redundant mate in an IP network configuration, 
use a Category 5 shielded twisted pair (STP) crossover cable. Using the crossover 
cable, connect Ethernet 1 on the primary board to Ethernet 1 on the backup board. 
Using standard Ethernet cables, connect the Ethernet 2 connectors on both boards to 
the IP network connectors. 
Note: Dialogic recommends using a private Ethernet link to connect the redundant 
boards to avoid loss or delay of vital checkpoint messages. However, if each board in 
the redundant pair requires multi-homing, you can use Ethernet 1 for both the 
redundant pathway and for SIGTRAN network access. In this configuration, the 
Ethernet 1 on each board is connected to what is shown as an IP network cloud in 
the illustrations that follow (just as the Ethernet 2 connectors are). Be aware that 
this greatly increases the chance of lost or delayed checkpoint messages which can 
result in the backup having outdated information. 
You must specify the IP address of the TX board’s redundant mate using the mate 
command in the txconfig utility. You must also define the IP interface address using 
the ifcreate command (for interface 1) in the txconfig utility. For more information, 
refer to the Dialogic® NaturalAccess™ Signaling Software Configuration Manual
