Let's try to define the terminolog;

	oc3	3*sts-1	(=3*ds3)
	oc3c	3*sts-1 concatenated (vc4, or one container 1920 bytes)
	oc12	12*sts-1 (=12*ds3)
	oc12c	12*sts-1 concatenated (can carry a STM-4, 7680 bytes)


Most (all?) data equipment uses ocXXc chanels, so I asume that is what
we are talking about.


ATM	OC12c-celltax	=	'oc9' worth of IP traffic (467M)
POS	OC12c-frametax	=	'oc11' worth of IP traffic ((580M)

This is before we look at system performance, routers understand IP,
Switches does not.
