Two-Wire Leased Line Connection
MT5600BA: Plug one end of a two-wire phone cable into the modem’s LINE jack,
and connect the other end to a leased line wall jack or terminals.
MT5600BL: Plug one end of a two-wire phone cable into the modem’s LEASED jack,
and connect the other end to a leased line wall jack or terminals.
Four-Wire Leased Line Connection
On an MT5600BL only, plug one end of a four-wire phone cable into the modem’s
LEASED jack, and connect the other end to a four-wire leased line wall jack or termi-
nals. For dial backup operation, plug one end of the modular phone cable into the
modem’s LINE jack, and the other end into a PSTN wall jack.
Phone Connection
For voice-only calls, plug a telephone into the modem’s PHONE jack (optional).
Power Connection
Plug the power transformer into an AC power outlet or power strip. Plug the power
transformer’s cable into the POWER jack on the modem.
Note:
Use only the power transformer supplied with the modem. Use of any other
transformer voids the warranty and can damage the modem.
Surge Protectors and Lightning
Power surges and other transient voltages on power lines, such as those caused by
lightning strikes, can damage or destroy your modem. Therefore, we recommend
that you plug the modem into a surge protector rather than directly into a wall out-
let, preferably a surge protector that provides protection against electrical spikes on
the phone line as well as on the power line. Note that not even a surge protector can
guard against damage from a nearby lightning strike. During an electrical storm, it
is safest to unplug your computer equipment from both the power outlet and the
telephone line.
Power-On Test
Test the modem by turning it on (a power switch is located on the front panel).
When you apply power, the modem performs a diagnostic self-test, indicated by the
TM indicator lighting for a few seconds, after which the LCD should light. If this
does not happen, check that the power switch is on, the power transformer is sol-
idly connected, and the AC outlet is live. If these measures do not work, see Chapter
8, “Solving Problems.”
