Chapter 6
Chapter 6 provides a detailed description of the µLink
System as well as a brief description of the Line
Replaceable Units (LRUs) comprising the system.
This chapter is aimed at providing the service
technician with an understanding of the function and
operation of the µLink System.
µµLink System
Description
The µLink System is a Direct Sequence Spread
Spectrum Digital Radio operating in the 2.4 GHz ISM
frequency band. Various payload data interfaces can
be installed, ie. T1 and E1. The µLink system can be
extended to include other frequency bands merely by
using a different microwave transceiver in the Outdoor
Unit (OU). The Indoor Unit (IU) is not dependent on
the frequency band used.
A µLink Radio Relay Station comprises a single IU, an
OU (with integral antenna), interconnected by a custom
cable. On-site management and maintenance is achieved
by using a Craft Terminal that interfaces to the IU.
A radio relay link consists of a complementary pair of
µLink stations. It is possible to extend range by
linking further station pairs in a multiple hop
configuration.
The following options may be added to a µLink
Digital Radio System:
• Local area network for networking of multiple
radio relay stations.
• IP routers, bridges, and gateways for networking to
the Telecommunications Network Management
(TNM) system.
