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.
