Thank you for the enlightenment and patience with a neophyte; then perhaps I should consider the JTAG route, if it is true that my provider will not then 'upgrade' an owned modem. One theory for the problems I am seeing (the modem shuts itself down and reboots once or twice a day) is that it might be due to a failed attempt by the provider to update the firmware.
I have no interest in any modified firmware, just a legitimate update; no offense intended to anyone.

My very thoughts; two technicians from Charter/Optimum have visited in the last few days and the signal strengths are just fine, and I approach this forum only after having reprovisoned a second modem and am still seeing the same problem.
The first modem was a SB5101, the second a SB5101U, both on rather old firmware.
I very much appreciate your thoughts, as I am somewhat at a loss.
I could call in a third visit, but as Einstein noted
Insanity: doing the same thing over and over again and expecting different results.
I attach a typical log in the hope that it might shed some light
At first I thought I had found the problem as the first modem had one of the ethernet pins missed by the wave soldering, but when the problem returned on the second modem, I knew I was wrong.

Show me the signal page.
Your ISP will update the firmware if it is needed by them.
I would lease a modem for 1 month, show the issue exists, then escalTE THE CALL/PROBLEM TO A sUPERVISOR
sorry 4 the caps at the end..hit the shift/caps lock button
Southern,
TLV-11 Oid is a normal response for asking and not getting something. Maybe the CMTS is looking for a D3 response and he doesnt offer the right value..no biggie
the DCC-ACK is though..
he cant change channels and then ack then cmts. Still think he has a signal issue

They did not seem very interested in the log, just testing the cabling and signal strength. They are both untouched modems running the original firmware.
your upstream is too high, your modem is at the edge. the 5101 can go to + 53, but I have seen + 49 at the edge and when you have hot dats and cool nights, the line amp/NODES have an issue with temp correction

Interesting, the techie said 45 - 51 dBmV was the upstream range (.177 - .355 V), and if I understand correctly, attenuators come in steps of 3 dB, in which case the reported 47.2 dBmV is right around the mark.

For those that might be interested, the problem seems to have gone away (since Aug 10th), as I haven't seen an error in the log for 4 days now. i.e. I believe the problem was at their end, not mine.
