Change working mode: HSB 1+1 to SD 1+1 RTN 950

Hello!

In the 1+1 HSB protection mode, the equipment provides a 1+1 hot standby configuration for the IF boards and ODUs at both ends of each hop of radio link, implementing the protection.

In the 1+1 SD protection mode, the system uses two antennas with a space distance to receive the same RF signal. The equipment selects from the two received signals. With the 1+1 SD protection, the impact of the fading on signal transmission is reduced.

Surely you need a HW re-installation and a SW reconfiguration, as I just explained two different HW configurations.

if this link operates in 128QAM modulation, from the U2000 simply changed the modulation to 256QAM, of course you have the license, to pass for example from 200Mbps to 400Mbps.

Please refer to the link below for more details:

Hi sir

Thanks for the info, we already implemented upgrading it to 256 QAM unfortunately it was unsuccessful and reverts back to 128 QAM.

You need to prepare a link budget for the SD configuration to also verify that your link will allow.
