cmCpeBoardOperState is a read-only enumeration reporting whether a specific customer-premises DSL modem is currently disabled or enabled from the system's perspective. An administrator checks this when a subscriber reports no service, to see whether the CPE itself has been administratively taken out of service rather than experiencing a physical line fault. For example, if a customer's cmCpeBoardOperState unexpectedly shows disabled, the operator would investigate whether that account was disabled in error before dispatching a technician.
