What do you mean by watchdog hardware?

This is specific hardware, normally very low cost. Causes an init when certain conditions are met
Or it could be a routine within certain hardware and/or software.

Very common.

Found the time to look into this a bit more on telecom side.

Seems they would use two watchdogs as a minimum (maybe even more).

One to halt state upon detection of over-voltage and to put cards/lines in a protected state. then another to re-init upon that fault detection.

Again I don't know anything about Bells hardware, but whatever bug they have needs to be fixed.

What this individual experienced isn't normal at all.
