The AMR-100 has fixed amount of memory that it uses to track events. Because it would
take too much memory to track all events, two summary tables are provided to assist you in
troubleshooting any problems.
1. The 1-Minute Summary takes snap shot every minute and records a summary of
errors in that minute.
2. The 15-Minute Summary takes a snap shot every 15 minutes and records a summary
of errors in that time frame.
The following two illustrations show the two summary pages. Both report the same things,
but the time of each varies in accordance to its page. The 1-Minute Summary has an entry
every minute and the 15-Minute Summary has an entry every 15 minutes.
The columns have the same names:
• Packets processed: How many data packets have been sent to and received by the
AMR-100
• Multicast Datagrams: If you receive a live stream, this records the number data
packets sent and received by the AMR-100
• Bad Blocks: The shows the number of blocks that could be corrected by Forward
Error Correction (FEC)
• Continuity Errors: This records the number of MPEG frames that were lost. This
should correspond to the bad blocks count. The transponder that AMB-OS and the
CRC use is a DVB compliant transponder and uses MPEG frames to transmit data.
• EbNo: This is the Energy per Bit above Noise and measures the quality of the data in
the carrier. It is possible to have a low AGC (low RF), but a high Eb/No if the data is
