2 Installation

Note: The Federal Communications Commission (FCC), Industry Canada, and other government agencies may impose certain restrictions on equipment connected to public telephone systems. For more information, see Appendix A.

Phone Connection

For voice-only calls, you can optionally plug a telephone into the modem’s PHONE jack.

Microphone Connection (MT5600DSDV only)

Plug the microphone plug of the supplied headset into the MIC jack on the side of the modem. Optionally, plug an unamplified microphone into the MIC jack. The microphone should have a 1/8-inch mini plug.

Speaker Connection (MT5600DSDV only)

Plug the speaker plug of the supplied headset into the SPKR jack on the side of the modem. Optionally, use a 1/8-inch-plug male-to-male stereo patch cord to connect the SPKR jack on the side of the modem to the LINE IN jack on your sound card.

If you do not have a sound card, you can plug an amplified speaker directly into the SPKR jack.

Power Connection

Plug the power supply module into an AC power outlet or power strip. Plug the power supply’s cable into the PWR jack on the modem.

Note: Use only the power supply supplied with the modem. Use of any other power supply will void the warranty and could damage the modem.

Power-On Test

Test the modem by turning it on (a power switch is located on the right side). When you apply power, the modem performs a diagnostic self-test, indicated by several indicators flashing for a second or two, after which the 56 indicator should light. If this does not happen, check that the power switch is on, the power supply is solidly connected, and the AC outlet is live. If these measures do not work, see Chapter 6, “Solving Problems.”

Surge Protectors and Lightning

Because of power surges and other transient voltages on power and telephone lines, we recommend that you plug the modem into a surge protector rather than directly into a wall outlet, preferably a surge protector that provides protection against electrical spikes on the telephone line as well as on the power line. Please note, however, that not even a surge protector can guard against damage from a nearby lightning strike.
