Chapter 1 Introduction WinLink 1000 Installation and Operation Manual
The alarm connector is available as an ordering option for the IDU-E.
Link Compatibility
WinLink 1000 indicates the version compatibility via software traps. As
new hardware is added to existing networks compatibility issues may
arise. Trap messages indicate the problem and suggest upgrades as
appropriate.
Optional External Antenna
WinLink 1000 supports configuration of an external antenna. In this
configuration, the outdoor unit is supplied with an N-type connector
that connects through a coax cable to the external antenna.
An external antenna can extend the range of the link, and in some
cases, may help to reduce environmental interferences. Various
external antennas are available for the WinLink 1000 operating
frequencies.
For example, an optional flat panel 28 dBi external antenna increases
the operation range of WinLink 1000 up to 80 km (50 miles).
Hub Site Synchronization
When several WinLink 1000 units are collocated at a common hub site
interference may occur from one unit to another. WinLink 1000 ODU
units are supplied with special hardware for the collocation of up to
eight units.
Using a method called Hub Site Synchronization (HSS) an external cable
is connected to all collocated WinLink 1000 ODUs, this cable carries
pulses sent to each ODU, which synchronize their transmission with
each other. (See
Appendix F for more details).
E1 Trunk Redundancy
IDU-R units have a secondary E1 input which may be connected to
external equipment other than the ODU. This provides backup in the
event of failure of either the air interface link of the WinLink 1000, or
the secondary E1 link.
The user configures which of the two links is the main link and which is
the backup link.
