commands, respectively.
4.5 PVC CONNECTIONS
The SmartCell 6A000 supports Permanent Virtual Circuits (PVCs), both point-to-point and point-to-multipoint. Use
PVCs to connect devices (that do not support SVCs) to a switch’s local client. Also, use PVCs to make connections
through the SmartCell 6A000 between devices that support only PVCs.
Use point-to-point PVCs to connect one end node to another for two-way communication. Use point-to-multipoint
PVCs to connect a broadcast end node to a group of receiving end nodes; traffic is one way.
Note PVCs use traffic descriptors to define their traffic characteristics. If you are
unfamiliar with traffic descriptors, see Section 4.6.1, “Traffic Descriptors.”
