In one frame or short buffer mode the delay through the receive buffer is reduced to an
average delay of 96 or 48 bits. In bypass mode the time slot assigner is disabled. In this
case SYPR programmed as input is ignored. Slips are performed in all buffer modes
except bypass mode. After a slip is detected the read pointer is adjusted to one half of
the current buffer size.
