What is the data throughput speed of an ISDN PRI connection? I seem to have some contradicting statements with my study guide...yikes!!!

Thank you in advance for any help!

    ISDN PRI is 23 64Kbps B channels and 1 64Kbps D Channel. D is for control so I would think the maximum throughput would be 64 x 23 = 1.472. I believe I read somewhere that it was like 1.555 so I wonder if they count the D channel in with the B channels.

    I know for a fact that ISDN BRI is 128Kbps maximum throughput, 2 64Kbps B channels and 1 16Kbps D channel.
