Microwave transmission from an end-to-end perspective

MINI-LINK TN provides a platform for flexible,

scalable and cost-effective wireless transmission.

With microwave nodes optimized for networks,

it targets transmission networks for 2G and 3G

as well as fixed and broadband applications.

MINI-LINK TN offers advantages on all sites

with features that allow a flexible network design,

fast implementation and carrier class networks.

The system provides scalable nodes with inte-

grated traffic routing, PDH and SDH multiplexing

and protection mechanisms on both node and

network level. Configurations ranges from small

edge nodes with one single radio terminal to

large aggregation nodes where all the traffic from

a number of southbound links are aggregated

into one link, microwave, cupper or optical, in

the northbound direction.

The software configurable traffic routing mini-

mizes the use of cables, improves network

quality and facilitates control from a remote

location. MINI-LINK TN also offers a TCP/IP and

SNMP based management concept. The use of

open interfaces ensures inter-operability between

different parts and services in the network.

Ericsson can provide one common radio unit for

the complete MINI-LINK point-to-point portfolio

that supports all capacity and modulation needs.

To increase the flexibility, MINI-LINK TN supports

a variety of optional features, enabled by Soft

Keys. For an installed node, new features or

functions can be added by software, locally or

remote, without any hardware change. This will

reduce cost and supports a true "invest-as-you-

grow" strategy.

Nodes designed for networks

MINI-LINK TN provides an end-to-end range of

nodes that are scalable in capacity and size,

suitable for all site types - from the edges of the

network to large aggregation nodes. With the

different magazines, plug-in-units and optional

features available, a tailor made solution for each

network site can be configured, starting from a

single radio link to a fully-fledged radio hub.

An Edge Node, is located at the edge of the

transmission network where all incoming traffic

is terminated. In MINI-LINK TN, an Edge Node

consists of one radio unit and a stand-alone

indoor unit (ATU), for un-protected configurations,

that includes modem and traffic interfaces. The

unit is self-contained, requiring no magazine,

and fits directly into a 19" rack. It provides full

flexibility in capacity allocation between Ethernet

and PDH traffic.

A microwave Aggregation Node main function

is to collect traffic from several sites and to

aggregate it into a higher capacity transmission

link. MINI-LINK TN provides a powerful high-

speed bus architecture that allows traffic to be

cross-connected between plug-in units. Both

package and circuit switched traffic can be

aggregated, without any external equipment.

The minimized use of cables and site equipment

results in few site visits, fast installation and pro-

visioning, easy capacity expansion and improved

network quality. Typically the node concept

reduces rack space requirements by up to 70 %

and it will at the same time lower CAPEX and

OPEX

Any frequency, capacity and modulation

MINI-LINK TN provides microwave transmission

from 2x2 to 64x2 Mbit/s in PDH and 155 Mbit/s

in SDH. With High Capacity PDH, a smooth

capacity-migration can be performed in existing

microwave networks. It operates within the 6 to

38 GHz frequency bands, utilizing C-QPSK, 16,

64 and 128 QAM modulation schemes.

The advanced microwave technology deployed in

MINI-LINK TN includes capacity and modulation

agile radio terminals. It means that capacity and

modulation scheme can be changed via software

by using Soft Keys, with no hardware changes.

This flexibility together with the powerful bus

architecture and traffic routing of MINI-LINK TN

makes it easy to re-configure networks from a

remote location.

Flexible Ethernet transport

All type of nodes in MINI-LINK TN handles

Ethernet traffic. The possibility to mix Ethernet

and PDH traffic reduces the need of cabling as

well as external equipment, and it results in a

very compact building practice. The total amount

of capacity in a node is software configurable,

and can easily be allocated and changed in small

steps, between PDH and Ethernet.

Soft Keys to increase flexibility

The traffic in the transmission networks will

change in the future, both in capacity and type

of traffic. To be prepared for these changes,

MINI-LINK TN supports several optional features,

enabled by Soft Keys. For an installed node, new

features or functions can be added by software,

locally or remote, without any hardware change.

For example: higher capacity, higher modulation

schemes can very quickly and easily be intro-

duced when and where it is needed, supporting

a true "invest-as-you-grow" strategy.

Advanced traffic handling and protection

MINI-LINK TN supports reliable ring and mesh

structures with capacities up to 155 Mbit/s. The

network protection mechanism works on E1 level

and is media independent, meaning that a combi-

nation of microwave, fiber and cupper can be

used.

The traffic handling function in the nodes have

no single point of failure. The separation of traffic

and control makes the system very robust and

enables, for example, hot-swap of plug-in boards.

In each node the software configurable traffic

routing function can cross-connect the traffic

on an E1 level. This can be done on site or from

a remote location.

In MINI-LINK TN, ATM aggregation functionality

can easily be added. With the introduction of

HSDPA in the mobile networks, ATM aggregation

can be used when the data services increase, in

order to better utilize transmission resources.

Efficient management systems

MINI-LINK ServiceOn Microwave is a powerful

network element manager for centralized opera-

tion and maintenance of all microwave radio

equipment supplied by Ericsson. It can be used

as a standalone system, or integrated in a higher

level network management environment using

standard protocols. The network control and

flexibility provided by the MINI-LINK ServiceOn

Microwave translate into low operating costs,

quick return on investment and a long-term

contribution to profitability.

MINI-LINK TN has an integrated IP router in each

node for handling of the DCN traffic. The IP DCN

can also be used as transport channel for other

equipment O&M data. A number of different alter-

natives to connect and transport DCN traffic are

supported.

Circuits can be routed end-to end through a

MINI-LINK TN network. This fully utilizes the

remote traffic routing capability of MINI-LINK TN.

Continuous re-configurations and upgrades to the

transmission networks are a big part of operating

costs, making the cost savings from an end-to-

end management system significant.
