The current operational state of the MAU. other(1) is returned if the MAU or interface is in a state other than one of the states 2 through 6. unknown(2) is returned when the true state of the MAU is unknown; for example, when it is being initialized. operational(3) state is fully functional, operates, and passes signals to its attached DTE. standby(4) state forces DI and CI to idle and the media transmitter or interface to idle or fault, if supported. Standby(4) mode only applies to link type MAUs. The state of zhoneMauMediaAvailable is unaffected. A MAU in shutdown(5) state assumes the same condition on DI, CI, and the media transmitter as though it were powered down or not connected. The MAU MAY return other(1) value for the zhoneMauJabberState and zhoneMauMediaAvailable objects when it is in this state. For an AUI, this state will remove power from the AUI. Setting this variable to the value reset(6) resets the MAU in the same manner as a power-off, power-on cycle of at least one-half second would. The agent is not required to return the value reset (6).
