Bandwidth in ISDN

I can't find to answer this question that come in my mind since I have not found good answers where I tried.
Let's take an ISDN BRI connection, normally one only B-channel is used as the call setup is terminated.
Some resource say that when the call set up is terminated and the circuit established, a bi-directional 64K B-channel is opened and data flows over that.
Just can't find to answer how this bandwidth is partitioned. I guess this one 64K channel is used for traffic inbound and outbound, but how the bandwidth is partitioned into this channel? Not strictly at the physical level, it would be sufficient for me to know how much bandwidth is reserved for outbound and inbound traffic (if it is!).
Thank You.

The 64k channel is symmetric, 64k up and 64k down.The only easy day was yesterday!
