Cabling your MT4X56USB

Cabling your MT4X56USB involves making the proper cable and power connections. Figure 2-2 shows the back panel connectors and the associated cable connections. To connect the cables to your MT4X56USB, do the following.

1.Connect the power supply to the MT4X56USB and a live AC outlet. To do this, insert the coaxial plug into the connector marked POWER on the back of the MT4X56USB and plug the AC power input plug into a live AC outlet.

2.Connect one end of the RJ-11 cable to Port 1 on the back of the MT4X56USB. Connect the other end to the line jack which provides access to the public phone system.

Repeat step 2 for up to four connections (Port 1 - Port 4).

3.Use the provided MT4X56USB cable to make either an “Upstream” or a “Downstream” Connection.

Upstream Connection: connect the flat (4-pin) end of the MT4X56USB cable to the connector marked USB - A on the back of your MT4X56USB. Connect the “D-shaped” end to the “Upstream” device (Hub input or additional MT4X56USBs).

Downstream Connection: connect the flat (4-pin) end of the MT4X56USB cable to the “Downstream” device (USB-supported peripheral such as a computer, printer, scanner, modem, or output Hub). Connect the “D-shaped” end to the connector marked USB - B on the back of your MT4X56USB.

CAUTION: Do NOT plug the “D-shaped” end of the USB cable into the USB-B port on the back of your MT4X56USB at this time.
