For this example, one Modemulator will be referred to as the “ local ” Modemulator, and the other will be
referred to as the “ remote ” Modemulator.
In this example, the local Modemulator’s dialing directory will be programmed to recognize the example
phone number 555-1234 and translate it into the IP address of the remote Modemulator.
Conversely, the remote Modemulator’s dialing directory will be programmed to recognize the example
phone number 555-5678 and translate it into the IP address of the local Modemulator.
Set-Up the Local Modemulator Dialing Directory
1. Power up the local Modemulator by plugging the provided power supply into the connector on the
back of the device, and then plug the PSU into a mains power outlet.
The Modemulator will take about two minutes to become operational.
2. Connect the local Modemulator Terminal port to a computer serial port. In the terminal application,
set this COM port for 9600bps, 8N1.
3. Consult the MVNO documentation for the static IP address assigned to the remote Modemulator
for CDMA networks or assigned to the SIM installed in remote Modemulator for GSM networks.
4. Enter the example phone number, port number (Modemulator listens to port 8888 by default), and
IP address (assigned by the MVNO) of the
remote Modemulator into the local Modemulator’s
dialing directory by typing the following command into the local Modemulator, substituting the
static IP address assigned by the MVNO for the remote Modemulator:
AT{Y=5551234:8888:xxx.xxx.xxx.xxx <Enter>
Modemulator should respond OK.
5. Type the following command to set the local Modemulator to auto-answer on one ring:
ATS0=1 <Enter>
Modemulator should respond OK.
6. Keep the local Modemulator powered-up and connected to the computer serial port.
Set-Up the Remote Modemulator Dialing Directory
1. Power up the remote Modemulator by plugging the provided power supply into the connector on
the back of the device, and then plug the PSU into a mains power outlet.
