Chapter 1 Introduction WinLink 1000 Installation and Operation Manual
Alternatively each site can be configured or monitored via a Telnet
terminal.
Diagnostics and Performance Monitoring
WinLink 1000 supports activating local and remote loopbacks on E1/T1
links.
WinLink 1000 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 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 Rate Modulation (ARA)
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
