Upgrade and downgrade protection
73.2.2 Radio protection
Radio protection upgrade applies when converting from 1+0 not protected to 1+1
HSB, HSB SD, or FD radio protection configuration.
Note: With MPT-MC only the 1+1 HSB configuration is available.
Radio protection downgrade applies when converting from 1+1 HSB, HSB SD, or FD
protection to 1+0 not protected radio configuration. Radio protection downgrade
requires a power cycle of the NE.
Direct conversion from 1+1 FD to 1+1 HSB protection is not allowed. To switch from
1+1 FD to 1+1 HSB, the 1+1 FD protection must be removed and the 1+1 HSB
protection created.
There are no steps included to account for the required changes to the MPT-HL shelf
diplexer configuration or outside plant configuration, such as ODU/antenna
configuration, RF coupler, waveguide, and grounding.
See the 9500 MPR Hardware Installation and Replacement Manual for information
about installation and cabling for radio protection.
73.2.3 Modulation scheme
The modulation scheme conversion applies when converting from static to adaptive
radio profile and the reverse.
To change modulation scheme, ATPC must be disabled, radio configuration must be
1+0 not protected, and license key must support adaptive modulation.
Converting from static to adaptive radio profile, all existing TDM2TDM and
TDM2ETH cross-connections must be supported by the lowest adaptive modulation
profile (4 QAM). When all existing TDM2TDM and TDM2ETH cross-connections are
supported by the lowest adaptive modulation profile (4 QAM), all the existing
TDM2TDM and TDM2ETH cross-connections are kept and the residual bandwidth
for new TDM2TDM and TEM2ETH cross-connections will be recomputed. When all
