8.7 Replaceable Flash Card for MU-12
The flash card on MU-12 is replaceable. See Setting IDB Parameters for more
information.
8.8 Operator Interface
The Man Machine Interface (MMI) is based on visual indicators and buttons
located on the hardware units in the MU.
For more information about the operator interface, see Optical Indicators and
Switches.
8.9 Optical Fiber Interface
The optical fiber carries traffic and timing signals between the MU and each
RRU-N. The optical cable is routed to the IF card-MU through up to three holes
of the MU. The cable gland for the optical cable is delivered mounted on the
optical cable. See the figures below.
