MODEM 32144
2.1.2 C
ONNECTIONS
Fig. 2-1 shows how the modem is
connected to the computer or
terminal, power, phone lines, and
handset (optional). Do not install
the modem more than 50 feet
(15.2 m) from the DTE. This is
the EIA recommended maximum
length for interface cable.
For all applications—
• Connect the modem connector
marked "DTE" to the computer
or other DTE. Use an EIA
RS-232 interface cable (not
supplied with the modem)
to make this connection.
• Attach the power transformer
cable (supplied with the
modem) to the modem
receptacle marked "POWER,"
and plug the other end into a
115-VAC power outlet.
For dialup applications—
• Connect the modem to the
telephone line modular wall
jack, as follows: Use the cable
(supplied) that has an eight-pin
modular connector on one end
and a six-pin modular
connector on the other. Plug
the eight-pin connector end of
the cable into the modem jack
labeled "TX DIAL." Then plug
the six-pin connector end into
the telephone line modular
wall jack. Do not bundle the
telephone and EIA interface
cables together.

• Optional: If you want to use
the telephone line for voice
transmissions (when the
modem is not operating in
data mode) or for manual
dial operation, plug a standard
telephone set into the jack in
the rear of the modem labeled
"PHONE."
For leased line applications—
• Attach the six-pin modular-
connector end of the four-
conductor cable (supplied) to
the modem connector labeled
"LEASED LINE." Attach the
spade-lug end of the cable into
the line terminal block.
The same cable is used whether
the leased line is a 4-wire or
2-wire line. In a 4-wire
application, the green and red
wires are the TRANSMIT pair
of wires, and the yellow and
black wires are the RECEIVE
pair. When the cable is
connected to a 2-wire line, only
its green and red wires are used
(and the yellow and black wires
should be cut off).
