Introduction
1 Introduction
1.1 General
The purpose of this description is to give the reader detailed information on
MINI-LINK PT 2010, both from a technical and functional perspective.
MINI-LINK PT 2010 is a complete microwave modem and radio unit with the
capability of handling IP and Ethernet traffic using all the required frequencies
in the 6–42 GHz range.
MINI-LINK PT 2010 is an all-outdoor Packet Terminal, housed in a radio unit
case. It is suitable for repeater and end sites due to the small footprint and
the easy mountability.
Some functions described in this document are subject to license handling, that
is, a soft key is required to enable a specific function.
1.1.1 Packet Transport in Microwave Networks
Compared to other transmission technologies, a microwave link can be
characterized as a limited bandwidth connection. This implies that microwave
equipment must be designed to enable maximum packet payload throughput
in the available bandwidth over the radio interface. The following features
improve the link efficiency:
Congestion Handling/Priority Queues
For connections with limited bandwidth it is important to support a mechanism
that prioritizes high priority packets when a connection is congested.
Adaptive Modulation
Adaptive modulation seeks continuously to use the modulation alternatives that
will maximize throughput under different conditions.
Low Residual BER
Microwave links operate with large fade margins and forward error correction
resulting in low residual BER level, typically 10-12.
Buffering Capabilities
Buffering capacities are 64 MB in the WAN direction. Each TC can use up
to 128 blocks, of 64 kB each.

System Overview
MINI-LINK PT 2010 is a stand-alone product integrating the system platform
providing traffic and system control, with microwave transmission from 8 to
406 Mbps.
MINI-LINK PT 2010 operates within the 6 to 42 GHz frequency bands, using
4, 16, 32, 64, 128, 256, and 512 QAM modulation schemes, also supporting
Hitless Adaptive Modulation.
MINI-LINK PT 2010 is an all-outdoor system. It is connected with a DC supply
voltage and an optical fiber cable.
For dual MINI-LINK PT 2010 installation systems, two Packet Terminals and
one or two antennas are used. When using one antenna, the two Packet
Terminals are connected to the antenna using a power splitter.
The Packet Terminal and the antenna are easily installed on a wide range of
support structures. The Packet Terminal is fitted directly to the antenna as
standard, integrated installation. The Packet Terminal and the antenna can
also be fitted separately and connected by a flexible waveguide. In all cases,
the antenna is easily aligned and the Packet Terminal can be disconnected and
replaced without affecting the antenna alignment.
The Packet Terminal is described in Section 8.1 on page 32.
The antennas are described in Section 8.2 on page 34.

Technical Description
4 Ethernet Traffic Handling in MINI-LINK
PT 2010
MINI-LINK PT 2010 supports all-IP and Native Ethernet simultaneously.
Ethernet traffic is sent over a hop as Ethernet over packet link (Native Ethernet).
The Ethernet LAN ports are described in Table 1.
Table 1 Ethernet LAN Port Properties
Ethernet LAN port properties Description
SFP modules SFP plug-in module is supported with
1 Gbps optical interface.
Standard frame sizes Up to 2,000 bytes when
used as an external interface
(IEEE802.3as-2006).
Up to 2,048 bytes when used as an
internal interface
Jumbo frames 9,216 byte frame size for data
applications
Connectors/cables Single/multi-mode fiber with LC
connector for the optical i/f.
4.1 Ethernet WAN Buffer
The WAN port buffer in MINI-LINK PT 2010 has been designed to handle
burst and congestion in order to provide a high link utilization and goodput for
high-speed data traffic.
Since extensive buffering has a negative impact on frame delay variation, it is
important to have the possibility to configure buffer/queue size for different
traffic classes independently.
This means that queues configured to handle delay variation sensitive traffic
such as synchronization traffic, shall be configured to be very short.
In contrast, for traffic queues for less delay variation sensitive traffic the
Transmission Control Protocol/Internet Protocol (TCP/IP) has a congestion
avoidance mechanism that is based on buffer utilization. In order to provide a
high link utilization and high TCP goodput, queues configured to handle this
type of traffic needs to be in the area of hundreds of milliseconds at the smallest
congestion point, equivalent to the network end-to-end Round-Trip time.
