Figure 8 The main parts of a MINI-LINK E terminal
A MINI-LINK E terminal consists of an outdoor and indoor part. There are also
a number of well-adapted accessories, both hardware and software.
Outdoor Part
The outdoor part is fully independent of traffic capacity and supplied for various
frequency bands.
It consists of an antenna module, a Radio Unit (RAU) and associated
installation hardware. The antenna and the radio unit are either integrated or
installed separately. For protected systems (1+1), two radio units and one or
two antennas are used.
Indoor Part
The indoor par t, the access module, is fully independent of frequency band
and supplied in different versions for various traffic capacities and system
configurations. It can support up to four radios.
It consists of a Modem Unit (MMU) and an optional Switch Multiplexer Unit
(SMU), as well as an optional Service Access Unit (SAU), all housed in one
common Access Module Magazine (AMM). For protected systems, two MM Us
and one SMU are used.
The indoor par t is connected to the outdoor part with a single coaxial cable
(the radio cable).
For Ethernet traffic the optional ETU can be used, see Section 3.11 on page 69.
For ring protection the optional MINI-LINK Cross-connect Unit (MXU) can be
used, see Section 7.2 on page 115.
