WinLink1000 Installation and Operation Manual Chapter 1 Introduction
WinLink1000 constantly monitors the data transmission process,
evaluates received signal strength, and signal quality. It also monitors
received traffic and frame rate (FPS) for local and remote units.
Automatic Channel Select
Some versions of WinLink1000 have the Automatic Channel Select
feature, which operates via a Dynamic Frequency Selection (DFS)
mechanism. This enables coexistence with any radar system that may
be active in the area. WinLink1000 performs channel monitoring and
selects the channel with the lowest interference for the transmission.
WinLink1000 operation complies with ETSI requirements where the
ETSI version has been purchased.
Adaptive Rate Modulation (ARA)
WinLink1000 constantly monitors the link quality to make sure that the
maximum throughput is maintained. WinLink1000 automatically re-
evaluates the air transmission rate if the link quality reduces due to
interference or weather changes. A lower rate may be selected in order
to improve the link quality. Once the conditions have improved a faster
rate is automatically selected. Each side of the link is monitored and
adjusted independently. WinLink1000 selects the highest possible rate
to maintain the quality of the services selected.
Transmit Power Control
The Transmit Power Control (TPC) function, provides the capability of
defining the transmit power in order to comply with the ETSI standard
requirement of
30 dB maximum. See
Table 4-1 for full details of transmit power
control.
Alarm Connector
The IDU-C has two external alarm inputs in the form of dry-contact
relays. The Alarm interface is located on the front panel of the IDU-C
and is a 9-pin D-type female connector. The user enables or disables
each of the alarms and can configure the text that appears in the alarm
trap. The ODU sends the alarm within less than a second from actual
alarm trigger.
The alarm connector is available as an ordering option for the IDU-E.
