Here’s an overall report from my wellness summary tool. Includes ES if any. Shows some problems that I didn’t know about and which I need to investigate. We had a nearby lightning storm today, so modems were turned off and then back on.
Summary of DSL links’ wellbeing and error counts
────────────────────────
* There are 4 modems in total. They are: #1, #2, #3 and #4
* The active, contactable modems are: #1, #2 and #4
* The modem skip-list declared in config: #3 was skipped over and not queried; its state is unknown
* The modems successfully queried are: #1, #2 and #4
───────────────────────
***
*** There is some SERIOUS BADNESS !
*** All is not well ! 😦

───────────────────────
*** Note that modem #3 was skipped over and not queried; its state is unknown. ***

* HCD:❗So-called ‘hollow curve disease’ (HCD) defect detected in the downstream SNR-vs-tones curve of link #4. Serious fault. 🔺
Link #4: Summary: tone 52 is 1.83088 dB below chord 2: (tones 45-62); ❗
Link #4: Details: chord 2: [ tone 45: 39.125 dB; curve midpoint test tone 52: 36.625 dB; tone 62: 37.5 dB ]; chord midpoint test tone 52: 38.45588 dB.

*❗ES (serious): Links with CRC errors at higher error rates, where the ES rate ≥ 60 ES / hr (†):
Link #2 downstream: latest period: ES per hr: 64.00, mean time between errors: 56.25 s, collection duration: 225 s
Link #2 downstream: 'previous' period: ES per hr: 100.00, mean time between errors: 36 s, collection duration: 900 s
--
* ES (not so serious): The following links have a few CRC errors, at lower error rates, where the ES rate < 60 ES / hr (†):
Link #1 downstream: latest period: ES per hr: 36.18, mean time between errors: 99.5 s, collection duration: 199 s
Link #1 downstream: 'previous' period: ES per hr: 24.00, mean time between errors: 150 s, collection duration: 900 s
Link #4 downstream: latest period: ES per hr: 18.18, mean time between errors: 198 s, collection duration: 198 s
Link #4 downstream: 'previous' period: ES per hr: 4.00, mean time between errors: 900 s, collection duration: 900 s
──────────────────────────────
(†) The duration of the ’latest‘ errored seconds (ES) collection
bucket is variable, with a _maximum_ of 15 mins. The buckets’
start times are always 15 mins apart. A ‘previous’ bucket's duration
is a fixed 15 mins. An ES is a 1 s time period in which one or more
errors are detected ie. corrupted data is received that either can not
be recovered by back-calculation using the additional redundant
error correction information included with each message, or by
being resent a certain maximum number of times, without being
received corrupted.
