WinLink 1000 Installation and Operation Manual Chapter 1 Introduction
Automatic Channel Select
Some versions of WinLink 1000 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. WinLink 1000 performs channel monitoring and
selects the channel with the lowest interference for the transmission.
WinLink 1000 operation complies with ETSI requirements where the
ETSI version has been purchased.
Adaptive Modulation
WinLink 1000 changes modulation automatically depending on channel
characteristics in order to guarantee continuation of service. The
adaptive modulation enables the user to maximize Ethernet
throughput without degradation of the TDM service quality. When
Ethernet only service is used, the adaptive modulation enables
improving the Ethernet performance in case of air performance
degradation (periodical interference or RSS changes).
In case of interference at one site, there is no need to use a lower
modulation at the other site (as in previous versions). In such a case
the actual rate changes automatically only at the problematic site,
while the second side of the link maintains the highest possible rate
(Asymmetric).
Adaptive modulation can be selected in both Installation and
Configuration wizards.
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 eight external alarm inputs and outputs in the form of
dry-contact relays. The Alarm interface is located on the front panel of
the IDU-C. The user enables or disables each of the alarms and
configures the text that appears in the alarm trap. The ODU sends the
alarm within less than a second from actual alarm trigger.
