Adding together the hex values for bands simple makes those bands available as the primary band (not for CA or separate UL/DL).
That's true for routers that don't support CA
Regarding the B525, it depends whether you have an old B525s-23
a (no CA) or a more recent B525s-65
a (released in 2017) that supports 2CA. See the B525s-65a product description
(Pdf page #5).
Of course, it makes no sense to try to configure CA on a router that does not support it. And the CA availabily also depends on the BTS.
But in both cases (avaliable bands or CA), the api is exactly the same.
If you take a more recent router like the B715 that supports 3CA, the api is still the same, without any additional parameter.
Also note there is no hex value for the B32 band
To check that a band is available, you have to use the net-mode-list api.
