PRI/BRI calculation examples

Looking for a few examples of how you calculate the bandwidth on these two ISDN services. Lecturer gave us a sample but he doesn't fully explain it all. Cheers Endo

Basic Service (BRI) = (2B + D = 2x64 + 16 = 144 Kbps service)
Primary Service (PRI) = (30B + D = 30x64 + 64 = 1.984Mbps ≈ E1 Speeds)
B = Data Channel
D = Control Channel

I think...
