1.2 Applications
MINI-LINK is a member of Ericsson’s large and extensive product portfolio for
telecommunications. The combined expertise of Ericsson, covering switching,
cellular technology, radio and networking, provides excellent turnkey project
management. MINI-LINK integrates fully with existing telecom networks, adding
new levels of flexibility. It has proved to be a reliable communication medium, a
highly competitive alternative to copper and fiber cable.
MINI-LINK E and E Micro provides point-to-point microwave transmission from
2 up to 34+2 (17x2) Mbit/s, operating within the 7 to 38 GHz frequency bands.
They are briefly described as follows:
•MINI-LINK E comprises an indoor access module and an outdoor radio
unit with antenna. It offers flexibility and capacity at small sites as well as
large multi-terminal sites. Terminals can be configured for different network
types: star, tree or ring. For protection, they can be configured either as a
1+1 system or as a ring structure.
•MINI-LINK E Micro is a compact all-outdoor terminal providing minimal
total site cost, typically used at end sites together with other all-outdoor
equipment.
A mobile transmission network is by far the most common application of
MINI-LINK E and E Micro, where they are deployed in the Low Capacity Radio
Access Network (LRAN).

2.1 Introduction
A terminal is one side of a microwave radio link hop, between two geographical
locations. The networks of today contain both single terminal sites and more
complex multi-terminal sites. MINI-LINK E and E Micro feature these types of
terminal configurations, further described in this chapter.

2.2 MINI-LINK E
Several MINI-LINK E terminals can be integrated into one common access
module. This enables extremely compact network sites as well as efficient
sharing of resources between different terminals, such as multiplexers, service
channel interfaces and support systems.
Traffic routing and re-routing within a network site can be performed with a
minimum of external cables. Traffic routing is software configured during station
setup.
Terminals can be configured for unprotected (1+0), protected (1+1) terminals
or ring protection.
Each terminal provides traffic capacity for up to 17x2 (34+2) Mbit/s.

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 part, 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 MMUs
and one SMU are used.
The indoor part 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.

2.2.2 Outdoor Installation
The radio unit and the antenna are easily installed on a wide range of support
structures.
The radio unit is fitted directly to the antenna as standard, integrated installation.
The radio unit and the antenna can also be fitted separately and connected by
a flexible waveguide.
In both cases, the antenna is easily aligned and the radio unit can be
disconnected and replaced without affecting the antenna alignment.

2.2.3 Indoor Installation
The indoor parts are fitted in 19" racks, in ETSI and BYB cabinets or directly
on the wall/desk. An access module consists of an Access Module Magazine
(AMM) and a set of different plug-in units. The following AMMs for different
applications are available as standard:
• AMM 1U for end terminals
• AMM 2U-3 for single or dual terminal sites, containing up to four plug-in units
• AMM 4U for more complex, multi-terminal sites, containing up to seven
plug-in units
The indoor part can be upgraded or reconfigured with plug-in units, providing
site flexibility.
The interconnection between the outdoor part (radio unit and antenna) and
the indoor part is a single coaxial cable carrying full duplex traffic, DC supply
voltage, service traffic as well as operation and maintenance data.

As a minimum a 1+0 terminal consists of:
•RAU
• Antenna
•AMM1U
• MMU
• Coaxial cable for interconnection
For traffic capacities 8x2, 17x2 and 4x8+2, an SMU is required. An SAU can be
added to the AMM to provide additional alarm and control interfaces, service
channels and other customer specific applications.

2.2.4.2 Protected Terminal (1+1)
As a minimum, a 1+1 terminal consists of:
• Two RAUs
• Two antennas or one antenna with a power splitter
• One AMM 2U-3 (or AMM 4U) with two MMUs and one SMU
• Two coaxial cables for interconnection
4493
Figure 16 1+1 configuration requires an AMM 2U-3 (AMM 4U can be used
as an alternative)
An SAU can also be added to the AMM to provide additional alarm and control
interfaces, service channels and other customer specific applications.
The radio units can be equipped with individual antennas or connected to a
common antenna. In the case of one common antenna, the two radio units
are connected by waveguides to a power splitter, fitted on a single-polarized
antenna.
Automatic switching can be in hot standby or in working standby (frequency
diversity). Receiver switching in space diversity systems is hitless.
In hot standby mode, one transmitter is working while the other one is in
standby (that is, not transmitting but ready to transmit if the active transmitter
malfunctions). Both radio units are receiving signals. The MMU selects the
best signal according to an alarm priority list, connects it first to the SMU for
demultiplexing and then to external equipment. See Section 3.9.2.6 on page 58
for further information about switching.
In working standby mode, both radio paths are active in parallel using different
frequencies.
The 1+1 configuration should be considered for important and/or heavy traffic
requiring high availability, but also if there are severe reflections and/or harsh
atmospheric conditions.
