SD channel numbers are OK, anyway the problem is not due to SD channel number, the problem is related with SD channels which on hopping TRXs.
No we have, static SDs.
There is no priority for allocation. MS can use SD from BCCH TRx or hopping TRx. Just the problem when immediate assingments on BCCH TRx everything is fine but when on hopping TRX we faces with block calls. And when i remove all SD channels from hopping TRXs, everything is going to be fine.
