    Default BW 64 Kbit/sec on PRI interface?

    Just confirming that BW is supposed to be 64 Kbit/sec on a VWIC2-1MFT-T1/E1 connected to a standard PRI? Why am I thinking that is is supposed to be 1536 Kbit/sec?

    The bandwidth of a DS0 is 64kbs so that is correct.

    Your only looking at the D channel. All of those other interfaces added up equal to your T1

    That doesn't matter. If you look at a single channel as the OP did it is only going to show you the bandwidth for that channel.
