3.1.4 Front Panel LED Indicators
There are 12 LEDs on the modem front panel to indicate status of the modem’s operation. They are
separated into three columns representing (from left to right) the Modulator status, the Demodulator
status and the Modem (Unit) status. The LED colors maintain a consistent meaning. Green signifies that
the indication is appropriate for normal operation, Yellow means that there is a condition not proper for
normal operation. Red indicates a fault condition that will result in lost communications.
Modem LED Indicators
1. Power: Green – Indicates the modem unit is currently under power.
2. Fault: Red – If summary fault condition exists from either Alarm A or B.
3. Stored Event: Yellow – Indicates that a condition or event has occurred that the
modem has stored in memory. The events may be viewed from the
Front Panel or in the Terminal mode.
4. Remote: Green – Indicates that the unit is set to respond to the remote control
input.
Modulator LED Indicators
1. Transmit On: Green – Indicates that the transmit output is currently active.
2. Major Alarm: Red – Indicates that the transmit direction has failed, losing traffic.
3. Minor Alarm: Yellow – Indicates a transmit warning condition exists.
4. Test Mode: Yellow – Indicates the modulator is involved in a current test mode
activity.
Demodulator LED Indicators
1. Signal Lock: Green – Indicates receiver lock to an incoming CXR and data
including FEC sync.
2. Major Alarm: Red – Indicates that the receive direction has failed, losing traffic.
3. Minor Alarm: Yellow – Indicates a receive warning condition exists, either an
incoming carrier with a low input level or a low E
b
/N
o
(programmable

3.1.4.1 Guide to Front Panel Monitor and Control
The front panel can be used to perform complete monitor and control of the modem setup and operating
parameters. The operation of the front panel becomes very easy after a short period of use in which the
user becomes familiar with the basic concepts and operations.
3.2 Modem Terminal Mode Control
The modem can be interactively monitored and controlled in the Terminal mode, with a full screen
presentation of current settings and status. Programming is accomplished by selecting the item to be
