Main Features and Characteristics

Main Features
The CFM–LM microwave radio system offers the following operation and maintenance facilities:
•
Radio performance monitoring,
•
Near-end and far–end loopback tests,
•
Software controlled parameters of the ODU and IDU.
The CFM-LM radio system offers a wide range of management capabilities including the remote
adjustment control, monitoring and testing.
In order to locate faults, the service engineer can access the Operation & Maintenance channel
using a PC with the appropriate software to perform loop tests. Loop tests are discussed in a
greater detail in paragraph Loop Tests, page 48.
The management terminal can be connected to the IDU through RS232 or Ethernet ports. The
local loop–back tests can also be performed from the local management interface on the IDU.
A wide range of parameters can be adjusted from the management terminal (PC) as well as through
the IDU management interface, - LCD and keypad.
The radio unit and the antenna are easily installed on a wide range of support structures.
Depending on the antenna used, the radio unit can be fitted directly to the antenna without a
waveguide feeder, or it can be fitted separately and connected with antenna with a flexible
waveguide. In either case the radio unit can be disconnected and replaced without affecting the
antenna alignment.
The IDU unit is fitted in 19" rack or on the wall or desk.
The management facilities of all SAF Tehnika products are being continuously developed and
improved making the setup, commissioning and maintenance easier.
