i really apologize for my wrong ans.
actually i had asked this from one engg. who is on contract basis with NOKIA he is from philipines.
he had given me that answer.
BUt one thing i want to quote
might be that flexihopper radio has a capacity of 32 channels but the equipments which we use like RRI card and FIU19E
they have the limioted capacity of 16
as mukul has quotted about the FIU
it comes out to be 16 again.
