S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
ProcessPHY[32:47]
If the ProcessPHY bit for a particular PHY is logic 0, then cells from that PHY will not be
searched or processed, and will be passed through the S/UNI-ATLAS-3200 unrecorded and
untouched, except for the PHY mapping functions, and adjustments to the length of the cells
(i.e. deleting prepends, postpends, and the HEC/UDF, or adding indeterminate data in these
positions). If the ProcessPHY bit is logic 1, then cells from that PHY are processed normally.
This feature is typically used when cells from a certain PHY are to be processed in another
device, such as another S/UNI-ATLAS-3200. This allows multiple S/UNI-ATLAS-3200s to
be cascaded, each handling cells from some of the PHYs. This can be used to support more
than 64K VCs in total.
