Each entry in this table represents a Soft
Permanent Virtual Channel Connection (Soft PVCC)
originating at a switch interface.
When a row is made active, an attempt is made
to set up a switched connection to an interface at
the destination switch. No objects (other than
atmSoftPVccRowStatus) can be set while the row is
active.
At the destination, the VCL may be defined (but
not cross-connected) prior to arrival of the Setup
request.
The combination of Slot/Port, atmVclVpi, and atmVclVci
specified in the index clause of this entry serves to
identify the VCL on the source interface. The
atmSoftPVccLeafReference object aids in distinguishing
between leaves of a point-to-multipoint Soft PVCC.
