zhoneMauMediaAvailable

If the	MAU or interface is a link or fiber type
(FOIRL,	10BASE-T, 10BASE-F) then this is
equivalent to the link test fail state/low light
function. For an AUI MAU this indicates	whether
or not loopback	is detected on the DI circuit.
              
other(1) is returned if	the mediaAvailable state
is not one of 2	through	11.
              
unknown(2) is returned when the	MAU's true state
is unknown; for	example, when it is being
initialized.  At power-up or following a reset,
the value of this attribute will be unknown for
AUI and	10BASE-FP MAUs.	 For these MAUs	loopback
will be	tested on each transmission during which
no collision is	detected. If DI	is receiving input
when DO	returns	to IDL after a transmission and
there has been no collision during the
transmission then loopback will	be detected. The
value of this attribute	will only change during
non-collided transmissions for AUI and
10BASE-FP MAUs.
              
For 100Mbps and	1000Mbps MAUs, the enumerations
match the states within	the respective link
integrity states.  Any MAU which implements
management of auto-negotiation will map	remote
fault indication to remote fault.
              
available(3) indicates that the	link, light, or
loopback is normal.  The value notAvailable(4)
indicates link loss, low light,	or no loopback.
              
remoteFault(5) indicates that a	fault has been
detected at the	remote end of the link.	This
value applies to 10BASE-FB, 100BASE-T4 Far End
Fault Indication and non-specified remote
faults from a system running auto-negotiation.
              
remoteJabber(7), remoteLinkLoss(8), and
remoteTest(9) SHOULD be	used instead of
remoteFault(5) where the reason	for remote
fault is identified in the remote signaling
protocol.
              
invalidSignal(6) indicates that	an invalid signal
has been received from the other end of	the link.
InvalidSignal(6) applies only to MAUs of type
10BASE-FB.
              
Where an IEEE Std 802.3u-1995 clause 22	MII
is present, a logic one	in the remote fault bit
(reference section 22.2.4.2.8 of that document)
maps to	the value remoteFault(5), and a	logic
zero in	the link status	bit (reference section
22.2.4.2.10 of that document) maps to the value
notAvailable(4).  The value notAvailable(4)
takes precedence over the value	remoteFault(5).
              
Any MAU	that implements	management of clause 37
Auto-Negotiation will map the received RF1 and
RF2 bit	values for Offline to offline(10), Link
Failure	to remoteFault(5) and Auto-Negotiation
Error to autoNegError(11).
