For more information about the trunk connections, refer to the Dialogic® NaturalAccess™ Signaling Software Configuration Manual.

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

Ethernet interfaces

The TX 4000 board has two 10/100Base-T Ethernet interfaces. These interfaces provide Ethernet connections that support auto-negotiation for 100Base-T full duplex/half duplex and 10Base-T full duplex/half duplex transmission. Each Ethernet interface can be manually configured if you are not using auto-negotiation.

The Ethernet interfaces provide a high-speed interface for connecting a TX 4000 board to either its redundant mate board or to a network of other SIGTRAN devices. Refer to Connecting TX boards for redundancy on page 34 for more information.
