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.
