This is a write-only control that resets all the WAN FPGA receive and transmit counters, described above, back to zero. Admins use this specifically after a satellite link event, such as re-pointing a dish or swapping a modem, to clear historical Rx error and Tx counters so a clean baseline can be established for the new physical condition. For example, writing 'reset' immediately after a technician re-aligns the satellite dish lets the next hour's CRC-error rate reflect only the new alignment, not the noisy period before the fix.
