MultiModemII User Guide

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 transformer module into an AC power outlet or power strip. Plug the trans- former module’s cable into the POWER jack on the modem.

Note: Use only the transformer supplied with the modem. Use of any other trans- former 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 (an on/off 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 supply is solidly con- nected, and the AC outlet is live. If these measures do not work, see Chapter 8, “Solving Problems.”
