Introduction
1 Introduction
1.1 General
MINI-LINK is the world’s most deployed microwave transmission system.
The MINI-LINK TN R4 product family is the latest addition, offering compact,
scalable and cost-effective solutions.
The system provides integrated traffic routing, high capacity traffic, PDH and
SDH multiplexing, Ethernet transport, ATM aggregation as well as protection
mechanisms on link and network level. The software configurable traffic routing
minimizes the use of cables, improves network quality and facilitates control
from a remote location. With the high level of integration, rack space can be
reduced by up to 70% compared to traditional solutions.
Configurations range from small end sites with one single radio terminal to large
hub sites where all the traffic from a number of southbound links is aggregated
into one link, microwave or optical, in the northbound direction.

Figure 4 Subracks
The AMM is a subrack.
The indoor part consists of an Access Module Magazine (AMM) with plug-in
units interconnected through a backplane. One plug-in unit occupies one slot in
the subrack. The subrack fits into standard 19" or metric racks.
The following text introduces the standard indoor units and their main functions.
For each unit there exist several types with different properties, further
described in Section 3 on page 9 and Section 4 on page 67.
Access Module Magazine
(AMM)
The AMM houses the plug-in units and
provides backplane interconnection of
traffic, power and control signals.
Node Processor Unit (NPU) The NPU handles the system’s control
functions. It also provides traffic and
management interfaces.
Line Termination Unit (LTU) The LTU provides PDH or SDH traffic
interfaces.
Modem Unit (MMU) The MMU constitutes the indoor part of a
Radio Terminal. It determines the traffic
capacity and modulation scheme.
Ethernet Interface Unit (ETU) The ETU provides Ethernet traffic
interfaces.

Technical Description
ATM Aggregation Unit (AAU) The AAU provides ATM aggregation of
traffic on E1 links.
Switch Multiplexer Unit (SMU) The SMU provides traffic and DCN
interfaces for MINI LINK E equipment.
Service Access Unit (SAU) The SAU3 provides additional DCN
capabilities.
SDH Cross connect Unit (SXU) The SXU provides mapping of Ethernet,
PDH and SDH traffic to and from STM-1
frames.
Power Filter Unit (PFU) The PFU filters the external power and
distributes the internal power to the
plug-in units via the backplane.
Fan Unit (FAU) The FAU provides cooling for the indoor
part.
The indoor part also includes cables and installation accessories.
The interconnection between the outdoor part (Radio Units and antennas)
and the indoor part is one coaxial cable per MMU carrying full duplex traffic,
DC supply voltage, as well as management data.
2.3 Outdoor Part
The outdoor part is supplied for various frequency bands. It consists of an
antenna, a Radio Unit (RAU) and associated installation hardware. For
protected (1+1) systems, two RAUs and one or two antennas are used. When
using one antenna, the two RAUs are connected to the antenna using a power
splitter.
The RAU and the antenna are easily installed on a wide range of support
structures. The RAU is fitted directly to the antenna as standard, integrated
installation. The RAU and the antenna can also be fitted separately and
connected by a flexible waveguide. In all cases, the antenna is easily aligned
and the RAU can be disconnected and replaced without affecting the antenna
alignment.
The RAU is described in Section 4.3 on page 80.
The antennas are described in Section 4.4 on page 87.

3 Basic Node
This section describes the Basic Node functions, hardware and traffic interfaces.
3.1 System Architecture
The system architecture is based on a Node Processor Unit (NPU)
communicating with other plug-in units, via buses in the subrack backplane.
The buses are used for traffic handling, system control and power distribution.

3.1.1 TDM Bus
The Time Division Multiplexing (TDM) bus is used for traffic routing between
the plug-in units. It is also used for routing of the DCN channels, used for
O&M data transport. The lowest switching level is E1 for traffic connections
and 64 kbit/s for DCN channels. The traffic connections on the TDM bus are
unstructured with independent timing.
The bus has a switching capacity of 820 Mbit/s. It is redundant for additional
protection against hardware failures.

Technical Description
3.1.2 PCI Bus
The Peripheral Component Interconnect (PCI) bus is a high bandwidth
multiplexed address/data bus used for control and supervision. Its main use is
for communication between the NPU software and other plug-in units’ software
and functional blocks
3.1.3 SPI Bus
The Serial Peripheral Interface (SPI) is a low speed synchronous serial
interface bus used for:
• Unit status control and LED indication
• Board Removal (BR) button used for unit replacement
• Inventory data
• Temperature and power supervision
• User I/O communication
• Reset of control and traffic logic
3.1.4 Power Bus
The external power supply is connected to a PFU. The internal power supply is
distributed via the Power bus to the other plug-in units. When using two PFUs
in a subrack, the bus is redundant.
3.1.5 BPI Bus
The Board Pair Interconnect (BPI) bus is used for communication between two
plug-in units in a protected (1+1) configuration, for example when using two
LTU 155 units in a Multiplexer Section Protection (MSP)1+1 configuration.
It also interconnects groups of four plug-in units, enabling board protection
schemes including three and four plug-in units.
3.1.6 High Speed Bus
The High Speed Bus joins services to services (for example Ethernet over
VCs dropped by ADM) and services to line interfaces (for example Ethernet
over modem), see Figure 6 on page 9. The high speed bus has dedicated
Point-to-Point connections from the NPU3 B to other PIUs.

Technical Description
3.2.1.2 Cooling
AMM 2p B can be used with or without forced air-cooling, depending on the
configuration. Forced air-cooling is provided by FAU4, placed vertically inside
the subrack. FAU4 holds three internal fans.
If the indoor location has other fan units, which provide sufficient cooling
through the subrack, the FAU4 can be omitted. However, air filters should be
present in the cabinet door.
Complete rules for cooling are available in MINI-LINK TN ETSI Product

3.2.3 AMM 20p B
The AMM 20p B is suitable for large-sized hub sites, for example at the
intersection between the optical network and the microwave network. It has
20 full-height slots, one housing an NPU1 B and two half-height slots housing
one or two PFU1.
The remaining slots can be equipped with MMU, LTU, AAU, SMU and ETU.
Protected pairs, require two MMUs in a protected (1+1) Radio Terminal, and
are positioned in adjacent slots starting with an even slot number.
A cable shelf is fitted directly underneath the subrack to enable neat handling of
