17.1.
In channel interleave mode data is output to the PCM data-out bus one channel at a time from each of the
connected SCTs until all channels of frame n from all each SCT has been place on the bus. This mode can
be used even when the connected SCTs are operating asynchronous to each other. The elastic stores will
manage slip conditions. See
17.2.
In frame-interleave mode, data is output to the PCM data-out bus one frame at a time from each of the
connected SCTs. This mode is used only when all connected SCTs are synchronous. In this mode, slip
conditions are not allowed. See
