What RADWIN MHS provides Appendix K
WinLink™ 1000 User Manual Release 1.9 K-2
• Designed to provide redundancy and high reliability for carrier class
operators
• Optimized for high capacity links operating in license-free bands
• A comprehensive solution providing protection against both equip-
ment failure and loss of air interface, by simple connectivity between
a primary link and a secondary link
The main service redundancy features of the RADWIN MHS are –
• TDM service cut-over from the primary to the secondary link is com-
pletely automatic
• TDM service cut-over time no more than 50 ms
• Automatic restore to primary link as soon as it becomes available
• Support for up to sixteen TDM channels for RADWIN 2000 and four
TDM channels for WinLink™ 1000.
MHS is supported between -
• two RADWIN 2000 links
• two WinLink™ 1000 links
• a RADWIN 2000 link and a WinLink™ 1000 link.
What RADWIN MHS provides
Equipment Protection
Equipment protection is provided for the electrically-active network ele-
ments, ODU and IDU.
The primary IDU and the secondary IDU are connected by a cable to moni-
tor failure and to control protection switching. Switching time is less than
50ms.
When connecting two WinLink™ 1000 links as 1+1, one dual-polarization
antenna can be shared by the primary link and the secondary link.
Air-Interface Protection
Air-Interface protection is unique to RADWIN and is optimized for wireless
links operating in license-free bands.
The primary link and the secondary link use different frequency channels. If
the air-interface of the primary link is disturbed and cannot carry the
required TDM service, then the system automatically switches to the secon-
dary link.
In addition, improved robustness and frequency planning flexibility is
achieved, as the primary and secondary air interfaces can operate in the
same frequency band or in different frequency bands.
Automatic Channel Selection (ACS) can be configured for each link to add
additional robustness.
