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.
