MINI-LINK TN R3 ETSI

The Diversity switches will work autonomous and are controlled by the switch
logic in the active MMU Rx. The switch logic is implemented as software in the
DP in the Control and Supervision block.

The Diversity switch will react on the Early Warning (EW) signals, Input Power
threshold alarm and FEC error alarm. The switch logic in one MMU needs
information from the other MMU, which is sent over the BPI bus.

Note that this switching is done under no fault conditions.

The switching principles are illustrated in Figure 74 on page 84.

Rx Equipment Protection

This protection case involves two types of switch, TDM Rx switch and Diversity
switch.

The TDM Rx switch is a logical switch used to switch over the traffic to the
redundant MMU, in case of a failure in the TDM Demultiplexer part of the active
