What protocol does Netbackup 8.3.x use to transfer data from Windows Server with MS-Windows policy?

Is it Windows SMB, or is Netbackup using its own protocol? I know this is a really basic question but I haven't been able to find out from the documentation or google. The background is I've come in...
Windows Server 2019

    Netbackup uses a customized version of the unix command TAR (in the bpbkar process) to create a bit stream over the network using tcp/1556, or 13724 or 13782. No SMB involved at all

    Process flow in : https://www.veritas.com/support/en_US/doc/86063237-127664549-0/v109483729-127664549

    You may search VOX for performance tuning hint and tricks. But first check NUMBER_DATA_BUFFERS and make sure the value is 256 or larger and not the default 64. You can see current value of NUMBER_DATA_BUFFERS in the activity monitor for each backup job (not control job).
