The S/T interface includes elastic buffers allowing continued operation under any phase
relationship between the IDL frame sync and the network. These buffers allow the frame
sync to wander with respect to the network up to 60 s peak-to-peak, exceeding the Q.502
requirements of 18 s peak-to-peak over a 24-hour period.
Figure C-6 shows a block diagram of the connection between four S/T interfaces and the
QUICC32. The diagram would be the same for up to 10 S/T interfaces.
