This trap is sent out whenever the when no valid PPPoE Active Discovery Offer (PADO)
is received in response to a PPPoE Active Discovery Initiation (PADI) packet
or if no valid PPPoE Active Discovery Session-confirmation (PADS) is received
in response to a PPPoE Active Discovery Request (PADR) packet.
This trap is sent out when when the radio board can't reach maximum
configured power. This can be caused by a combination of faulty
(or very long) coaxial cable connecting IDU and ODU and/or extremely
hot weather or just bad calibration data on the radio board.
This trap is sent out when the AGC Table is not calibrated.
SODU platform relies on accurate calibration of the receive gain
throughout the entire receive chain. If the table is not correctly calibrated
or gets corrupted in the field, the SODU will have to fall back on default receive
power adjustment algorithm, which may be far from optimal. This problem doesn't stop
an SODU from getting operational but the downstream link quality can suffer.
