results in 192 bits of channel data, plus a framing bit (F-bit), for a total of 193 bits
in a frame. Multiple frames are then grouped into superframes of 12 or 24
frames to provide for framing synchronization and signaling.
The Superframe( SF ) (also called D4 or 193S ) format defines a superframe as 12
frames.
The Extended Superframe ( ESF ) (also called 193E ) format groups 24 frames into
its superframe.
Both the SF and ESF framing formats provide an actual payload data rate of
1.536 Mbps (192/193 = 1.536/1.544).
For fractional T1 , the data rate is from 64k(N=1) to 1536k(N=24), according to
the T1 framing.
