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.
