Equipment Status
Monitoring
Description
a. Indoor Unit Status. The IU monitors the state of
the baseband signals in the Information Base and
informs the State and Mode Control function of
any problems or failures.
b. Outdoor Unit Status. The OU transmits a
periodic status message to the IU containing the
status of the OU. The Fault and Status Manager in
the IU monitors this, updates the Information Base
and informs the State and Mode Control function
of any problems.
c. Far-end Radio Station Status. The near end IU
transmits a periodic status message to the remote
IU. The Fault and Status Manager in the remote
IU determines if the transmitting IU is functioning
normally then updates the Information Base and
informs the State and Mode Control function of
any problems.
d. Health Monitoring. A background process
continuously checks the health of the system
hardware and software and reports any anomalies
to the Management Information Base (MIB). The
Fault Manager responds to this information.
