16 Link CX User Manual, Version A
BER Test
The following Bit Error Rate (BER) test is provided by Link CX:
• Pseudo random signal generator - capable of inserting a standard test signal for BER
measurements, and local- and remote-end loopback functions.
• BER measurements of radio link performance under normal operating conditions.
Software Downloading
The Web-based user interface enables off-line operation and SNMP updates of files. Alternatively, when
on-line, configuration can be updated from the NMS to the Link CX agent. Another way to upgrade
multiple Link CXs is to use FTP.
Note that the Link CX can hold two software loads in memory, which facilitates upgrading and reverting
to a previous software version.
Certain factory default software settings are always retained at the Link CX to safeguard against complete
failure of communications caused by equipment restart.
Performance Monitoring
Each Link CX gathers various statistics regarding radio link performance. The Web based user interface
can retrieve and analyze these statistics upon demand. In addition, the Web based user interface
manager processes its own general statistical data, based on the information that is received. Current
BER, Receive Signal Strength Indicator (RSSI), and other performance monitors are available for the
radio link.
The Web-based user interface is designed to easily interface with optional graph management software
packages for sophisticated performance presentation.
1-5 Typical Applications
Link CX gives the user great flexibility in setting up point-to-point radio links on a very cost effective
basis, because it avoids unnecessary outlays in expensive leased lines or fiber optic land-based lines.
Low cost of ownership makes return on investment (ROI) attractive compared to leased lines.
Link CX advantages over copper/fiber alternatives include: short installation time, easy maintenance
using NMS software, independence of competing PTTs, avoiding the need to secure normal
right-of-way and/or physical installation permits, and redeployable depending on changing needs.
The simplicity of the Link CX installation makes it easy for the user to implement Link CX in a variety of
applications. It also means that the user can conveniently move a previously installed Link CX to a new
location to meet the requirements of a changing system. Link CX enables seamless future software
upgradability, protecting customer investment, reducing logistics, spare parts and product stocking. The
following sections briefly describe typical applications.
