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.

Figure 2 Outdoor and indoor parts

A MINI-LINK TN R3 Network Element (NE) can, from a hardware and

installation point of view, be divided into two parts:

• Indoor part of two types:

− Access Module Magazine (AMM) with plug-in units, see Section 2.2

on page 5.

− Access Termination Unit (ATU), see Section 2.3 on page 6.

• Outdoor part, see Section 2.4 on page 7.

An NE with AMM can from a functional and configuration point of view be

divided into the following parts:

MINI-LINK TN R3 ETSI

Basic Node The Basic Node holds the system platform providing traffic

and system control, such as traffic routing, multiplexing,

protection mechanisms and management functions.

Specific plug-in units provide traffic interfaces, PDH, SDH

and Ethernet, for connection to network equipment such as

a radio base station, ADM or LAN. ATM aggregation is also

supported.

Finally, it includes indoor mechanical housing, power

distribution and cooling.

For more information, see Section 3 on page 9.

Radio Terminals Each Radio Terminal provides microwave transmission from

2x2to155Mbit/s,operatingwithinthe6to38GHzfrequency

bands, utilizing C-QPSK and 16, 64, 128 QAM modulation

schemes. It can be configured as unprotected (1+0) or

protected (1+1).

For more information, see Section 4 on page 59.

Figure 3 Basic Node and Radio Terminals

The Basic Node and Radio Terminal concept does not apply to an NE with

ATU. However, the self-contained unit implements applicable parts such as,

traffic interfaces, control and management functions, power, cooling and the

indoor part of an unprotected (1+0) Radio Terminal with C-QPSK modulation.

The management features and tools are described in Section 6 on page 105.
