Remote digital station maintenance software provides maintenance for a port administered as a digital station on the circuit pack. This strategy covers the in line errors log, initialization tests, periodic tests, craft-demanded tests, and alarm resolution and escalation. Each port, translated as a digital station on a digital line board, is running as a separate RDIG-STA MO of this type. Fault conditions discovered on one MO may or may not indicate faults on other MOs of the same type.
