(cont.)
PIIC1 Buffer CLK PLL
A PIIC interface has been selected but the data rate coming into the PIIC
card is either too high, too low or has too much jitter to generate a
consistent clock for the modem
PIIC2 Buffer Overflow
A PIIC interface has been selected but the data rate coming into the PIIC
card exceeds the expected data rate of the user configured PIIC data rate.
PIIC2 Buffer Underflow
A PIIC interface has been selected but the data rate coming into the PIIC
card is less than the expected data rate of the user configured PIIC data
rate.
PIIC2 Buffer CLK PLL
A PIIC interface has been selected but the data rate coming into the PIIC
card is either too high, too low or has too much jitter to generate a
consistent clock for the modem
Decompress Invalid
The modem is receiving data and there is a mismatch between what the far
end is configured for compression (enable/disable) and the alarmed demod
decompression (enable/disable).
LNB Current
The modem has exceeded the high or low current levels as programmed
by the user.
LNB Voltage
The modem detects that the LNB power connection is either OPEN or
SHORT.
Bad/Missing ACM
Packet
The modem's internal local / distant ACM messaging is either missing or
corrupt.
6.2.3.2 (Monitor:) Stored-Events
Event 005:255 12:11:36 25/04/14 ()
Rx: +--------------- Clr:N
An example of a Stored Events screen is shown here. Use the   arrow keys to select the
Event number or the Clr: option.
6.2.3.2.1 (Monitor: Stored-Events) Event ###
The event log can store up to 255 events. Use the  arrow keys to scroll from Event 001 to
Event 255. When an event occurs, the modem time- and date-stamps the fault and stores it in
the event log. Similarly, when the fault condition clears, the modem records this as well.
Note that, in accordance with European convention, the log shows the date in DAY-MONTH-
YEAR format and displays the time in military (24-hour) format.
The Stored Event reporting format follows the same symbol indications and meaning as
explained in Section 6.2.3.1 (Monitor:) Live-Alarms → Unit, Transmit, or Receive.
