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.
