Summary of DSL links’ wellbeing and error counts
─────────────────────────────────────
* There are 3 modems in total. They are: #1, #2 and #4
* The active, contactable modems are: #1, #2 and #4
* The modems successfully queried are: #1, #2 and #4

* Sync rate: The following link has a really low downstream sync rate, below min:
Link #2 downstream: current sync rate 916 kbps is below minimum expected downstream rate (2700 kbps) ❗Line #2 fault 🔺
--
* SNRM: The SNRM of the following link is out of range:
Link #2 downstream: current SNRM: 8.8 dB is too high; above the expected maximum SNRM ( 3.8 dB )
--
* HCD:❗So-called ‘hollow curve disease’ (HCD) defect detected in the downstream SNR-vs-tones curve. Serious fault. 🔺
Link #2: Summary: tone 62 is 0.55972 dB below chord 1: (tones 40-25.9375); ❗
Link #2: Details: chord 1: [ tone 40: 22.5 dB; curve midpoint test tone 62: 16.5625 dB; tone 25.9375: 25.9375 dB ]; chord midpoint test tone 62: 17.12222 dB.

* HCD:❗So-called ‘hollow curve disease’ (HCD) defect detected in the downstream SNR-vs-tones curve. Serious fault. 🔺
Link #4: Summary: tone 62 is 2.225 dB below chord 3: (tones 40-70);❗
Link #4: Details: chord 3: [ tone 40: 37.0625 dB; curve midpoint test tone 62: 34.1875 dB; tone 70: 34.625 dB ]; chord midpoint test tone 62: 36.41250 dB.

*❗ES (serious): Links with CRC errors at higher error rates, where the ES rate ≥ 60 ES / hr (†):
Link #2 downstream: 'previous' period: ES per hr: 1664.00, mean time between errors: 2.16 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.
