usable T1 bandwidth

How much of the 1.544 Mbits/second of a T1 are available to IP?  I know
some bits are taken for framing and such.  I think I remember it is
around 1.3 something.


It's 1.536 Mbps.  This is 64000 x 24.  The other 8k goes to framing
overhead.  It's full-duplex.  Can we stop the flames now?

Daniel Minoli has put out some good books that cover the low-layer
telecom transports, check with your local bookstore.
