6.6.4 Equipment Errors and Error Handling
On all boards, the equipment application handles the software and
hardware supervisioning.
Apart from this software based supervision, the hardware processor
has a watchdog as well, in orderd that if the software supervision
process does not update the watchdog circuitry, a processor restart is
initiated, cold restart.
6.6.5 Equipment Audit
At a hot start, the equipment is checked, trying to avoid traffic
disturbance as much as possible, while a hardware self-test is
performed at board restart and cold restart. At hot restart, the
equipment configuration is also checked and updated.
