POWER
12VDC
Connect the female end of the power adapter to the power receptacle on the rear panel of
your P841C. Connect the other end of the adapter to a power outlet.
LAN 10/100M The Ethernet interface is an RJ-45 connector. Use a crossover Ethernet cable to connect to a
hub or WAN switch. Use a straight-through Ethernet cable to connect to a computer.
CONSOLE The CONSOLE port is an RS-232 port for configuration of the P841C. Connect the male 9-pin
end of the console cable to the console port of the P841C. Connect the other end (either a
female 25-pin or female 9-pin) to a serial port (COM1, COM2 or other COM port) of your
computer. You can use an extension RS-232 cable if the enclosed one is too short.
VDSL Connect one end of a phone cable to the RJ-11 VDSL port and then connect the other end to
the telephone wall jack that connects to the subscriber's VDSL modem (P841).
PHONE The line from the subscriber's carries both VDSL and voice signals. The P841C has a built-in
splitter that separates the high frequency VDSL signal from the voice band signal and feeds
the VDSL signal to the P841C, while the voice band signal is diverted to the PHONE port.
Connect one end of a phone cable to the RJ-11 PHONE port and then connect the other end
to a PBX (Private Branch eXchange) or PSTN (Public Switched Telephone Network).
