Dual Ethernet X-Card

This card adds two RJ-45 Ethernet ports to the gateway for a total of three. The two
Ethernet ports on the X-Card are bridged with the gateway's main Ethernet port,
automatically becoming part of the same subnet.
The main Ethernet port on the rear panel is a high performance Ethernet port with data
rates up to 100 Mbps.
The Dual Ethernet X-Card provides additional Ethernet ports for applications requiring
lower throughput (in the range of 8–9 Mbps, or less if both ports are being used).
For example, the Ethernet ports on the Dual Ethernet X-Card are ideal for applications
that run on IP or other protocols that run on top of IP such as TCP and UDP.
Other suggested applications include:
