INTRODUCTION

This document describes the installation and provisioning of NEC iPasolink 400 microwave transmission
equipment. The information is based on the IDU firmware version 3.00.37. Additional information is
available in the manual iPasolink 400 Installation, Operation and Maintenance (NWD-115474-05E .
)
iPasolink 200 and iPasolink 1000 are very similar; however, there are some differences due to hardware
configurations. Reference is made to the appropriate equipment manuals.
Appendix D contains a quick provisioning guide. The quick guide is based on the configuration files that
have to be copied to the equipment before using the quick setup. The configuration files have to be
customised for each customer's basic HW configuration. Rebooting of the equipment with traffic
interruption will take place when the configuration file is copied to the equipment.

PRODUCT DESCRIPTION

The microwave transmission family (iPasolink 100/200, 400 and 1000) enables full duplex wireless
transmission between two modems at a rate of over 400 Mbit/s per direction. With XPIC and radio channel
aggregation, over 800 Mbit/s per radio channel can be achived.
The interfaces are based on the Ethernet, PDH and SDH standards.
Frequency division duplex is used. A pair of channels separated by certain duplex spacing is required.
iPasolink uses licensed frequency bands. The frequency administration provides interference-free channels
to different operators based on frequency planning: transmitter powers and antenna sizes etc are
specified. Alternatively, in some countries, the operator may be given a block allocation of spectrum and
the operator is then responsible for the proper frequency planning inside the block. In any case, the correct
operation is only possible with proper frequency planning so that adequate signal-to-interference margin is
available. Moreover, the microwave hop has to be planned according to current ITU-R methods in order to
ensure sufficient margin against fading.
NEC iPasolink uses the traditional split mount installation method: indoor unit (IDU), coaxial cable, outdoor
unit (ODU) and antenna. Different products of the iPasolink 100/200/400/1000 family may interface over
the air with certain limitations regarding maximum modulation. Fully outdoor versions (iPasolink AX, SX and
EX) are also available but are not over-the-air compatible with iPasolink 100, 200, 400 or 1000.
The indoor unit contains the baseband interfaces (nxE1, STM-1, FE or GbE) as well as modems, a power
supply (or supplies) and a control unit with NMS interfaces. The interconnecting cable uses intermediate
frequencies below 400 MHz for the data and control signals. It feeds the power to the outdoor unit at -48
