Event Description
Occurs when an external reference is the clock for the modem's TX,
but the external reference does not meet the expected clock rate.
Occurs when the Receive Automatic Gain Control cannot
compensate for the carrier power level because the carrier has too
little or too much power.
Occurs when the Receive Es/No is at or below the Receive Es/No
Alarm point
Occurs when packets are received by the demodulator and its
decompression setting does not match the compression setting for
the far side modulator.
Occurs when the high or low current limits for the Low Noise Block
Down Converter have been met.
Occurs when an Ethernet Interface is selected using the CONFIG:
Intf menu (Chapter 6 FRONT PANEL OPERATION Sect. 6.2.2.4)
as the active interface, but an Ethernet cable with Ethernet traffic
has not been detected on this physical port.
Occurs when the Tx output power has reached the Nominal +
Range sum (upper limit) and the modem can no longer increase its
Tx output power, but the remote reported Es/No is still lower than
the Target Es/No.
