awahma,
paging per second on which interface ? on the Abis/Air interface or on the A interface ?
On Air/Abis interfaces:
max = 33 pag/s without mCCCH
max = 66 pag/s with mCCCH
on A interface : it actually depends on your BSC processing capacity. in alcatel, BSC MX = 120 pag/s, BSC LEGACY = 70 pag/s.
Cheers
