AAL layers

i have this question ive ben stuck on for a while if anyone can help out, AAL2, AAL3/4 and layers receive data at 3 Mbps. a) How many cells are created per second from an AAL2? b) How many cells are created per second from an AAL3/4?

Ok, please double check all of my work. Number of cells per second = bps / cell size number of cells per second = 3 Mbps * 10^6 bits / 53 bytes * 8 bits ( Assuming a 5 byte header and 48 byte payload) number of cells per second = 300,000 bits / 424 bits 707.5 cells per second. Not a domain I'm familiar with, but it did seem to make sense to me. if there is an inherient cell size diffrence between aal2 and aal 3/4 I didnt find reference to it.
