Indoor Part with ATU

The Access Termination Unit implements the indoor part of a MINI-LINK TN
R3 Edge Node. It can be used for transmission of PDH traffic and in Ethernet
bridge applications.
The ATU comprises one self-contained unit, with a height of 1U, for installation
in 19" or metric racks. It can also be mounted on a wall, using a dedicated
mounting set, or put on a desk.

The ATU provides unprotected (1+0) microwave transmission within the 6 to
38 GHz frequency bands using C QPSK modulation, when connected to an
RAU with antenna. The interconnection between the ATU and the outdoor
part is one coaxial cable carrying full duplex traffic, DC supply voltage, and
management data.
Different ATU types are available offering traffic capacity from 2x2 to 17x2
Mbit/s, which can be shared between PDH traffic with a maximum of 8xE1 and
Ethernet traffic over a maximum of 16xE1.
The ATU is further described in Section 5 on page 93.

ATU
The SMU provides traffic and DCN interfaces
for MINI LINK E equipment.
The PFU filters the external power and
distributes the internal power to the plug-in
units via the backplane.
The FAU provides cooling for the indoor part.
