Table 12. Alarms
Alarm
id
Alarm Severity level Description
100 No sync Critical No valid ASI input stream detected.
101 ASI bitrate too high Critical The ASI input bitrate has exceeded the
configured maximum value.
121 Bitrate regulation in
progress
Filtered The regulation algorithm is estimating the
incoming bitrate to compensate for the
difference in PCR clocks on the source
encoder and the IP receiver. While this
alarm is active, the output bitrate may be
tuned beyond the limits of the ASI
specifications.
130 Ethernet link down Critical No link on Ethernet layer
131 Output buffer
overflow
Warning The total bitrate of the ASI input streams is
too high.
140 ARP unresolved Warning IP address is not resolved into physical
MAC address.
150 Sequence error Warning Analysis of the sequence number of the
RTP layer indicates that IP frames have
been lost or that they have been received
out of order.
151 No data received Warning No data received on Ethernet input for
stream
152 FEC threshold
exceeded
Warning The frequency of lost frames is higher than
the configured value. Threshold values are
configured per stream.
153 Input buffer
overflow
Warning The total bitrate of the IP input streams is
too high.
154 Data lost Critical The data stream received for a channel is
incomplete, and if running FEC, the FEC
engine is not able to recover all the lost
frames.
155 No lock Critical The IP receive channel is not able to find
an initial bitrate for the data received.
156 MIP not present Warning No MIP frames are received.
157 Too low latency for
FEC
Warning The preferred latency is set lower than the
latency required by the incoming stream.
160 SNTP server
unreachable
Warning Unit is not receiving answers from the
SNTP server.
161 Too high
temperature
Warning Internal temperature of unit is too high.
162 Defective fan Warning One or both of the fans are not spinning.
200 No GPS 1PPS
reference signal
Warning The 1PPS reference signal is lost. (The
regulator has however not lost
synchronization)
201 Lost GPS 1PPS
synchronization
Critical The clock synchronization mechanism has
been resynchronized due to too large
phase error.
