4-3-6 Modem Check (For LOGIQworks 3.0 optional)
4-3-6-1 Power-On
1.) Test the modem by turning it on (a power on/off 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.
2.) If this does not happen, check that the power switch is on, the power supply is solidly connected,
and the AC outlet is live.
4-3-6-2 Modem Ready
Whenever the system is rebooted, the modem does not go through power cycle. Sometimes it might
become necessary to restart the modem.
Check the following before restarting the modem:
• Check if there are 2 led lit on the modem. TR (Terminal Ready) and any of the 56,33,14 (indicate
the maximum data speed of the modem 56kbps, 33kbps or 14kbps).
• Call the modem phone number from a regular phone. Make sure when the modem answers the OH
(off hook) led is lit, and you hear the modem handshake.
These steps will make sure that the modem phone line is working correctly.
