Option #2: Crossover Cable
If you plan to network only two TalkSwitch units, it is possible to network them via a
LAN crossover cable.
Step A
Connect the two TalkSwitch 48-CA and/or 48-CVA units with a crossover cable. Make
sure you are using a crossover cable and not a regular LAN cable — see diagram.
Step B
Make sure a computer is connected to the phone system either via the USB or Serial port.
