Introduction
1 Introduction
1.1 General
MINI-LINK is the world’s most deployed microwave transmission system.
The MINI-LINK TN R3 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.

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 AMM 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.

MINI-LINK TN R3 ETSI
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 (or NPU2/NPU3 B for AMM
2p/AMM 2p B). The internal power supply is distributed via the Power bus to
the other plug-in units. When using two PFUs in an AMM, 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 PTP Connection
The Point-to-Point (PTP) connection joins services to services (for example
Ethernet over VCs dropped by ADM) and services to line interfaces (for example
Ethernet over modem or ATM over SDH modem), see Figure 8 on page 11.
