Dual Port
Adapter
The AT-2911GP adapter is a dual port adapter to connect a PC to two
separate networks. You can assign an IP address to each port.
After you physically install the AT-2911GP adapter on your Windows
operating system, you must install driver software. To install driver
software, see Chapter 3, “Installing the Driver Software” on page 35.
Note
You do not need to install driver software for Linux system because
Linux has inbox drivers for the AT-2911GP adapters.
Bridge to
Connect Two
Ports to One
Network
The AT-2911GP adapter is designed to connect a computer to the
Ethernet network using a fiber optic cable and a Powered Device (PD)
such as a Voice over IP (VoIP) phone, Wi-Fi access point, or security
camera, using a copper cable. In this setting, the adapter functions as a
bridge between the fiber port and copper port. Figure 2 on page 15
illustrates an example of a topology with VoIP phones.
Figure 2. Configuration Example
To use the AT-2911GP adapter to connect a VoIP phone as shown in
Figure 2, you must install the AT-MUX utility as well as driver software.
The AT-MUX utility bridges frames between the fiber optic port and copper
port. To install AT-MUX utility, see Chapter 4, “Installing the AT-MUX
