A configured SPVC that uses the switched connection between networks is a
permanent SPVC (P-SPVC). The switched connection at the NNI that enables
connectivity between networks is a switched SPVC (S-SPVC).

switched permanent virtual path (SPVP)
A a type of virtual path (VP) that allows configured SPVP endpoints in two
different frame relay or ATM networks to establish a switched connection
across network-to-network interfaces (NNIs). It is a logical connection, the
endpoints of which are configured by the network operator, but with a route is
selected automatically at call setup.

switched virtual channel (SVC), ATM networking
1 A virtual channel connection that is dynamically established and ended
through control signaling. The user defines the endpoints when the call is
initiated.

switched virtual circuit (SVC)
1 A type of virtual circuit (VC) that is established and torn down by
subscriber applications on an as-needed basis. It is a logical connection
that remains in place only for the duration of data transfer. User equipment
signals the desired destination, and the connection route is selected
automatically through SVC signaling.
