Note that I appreciate that this answer is far too late for your purposes - but maybe at some point in the future someone will want to translate the phrase and search through past questions. Please feel free to ignore it.

A Switched Virtual Circuit (SVC) is a type of connection that can be configured using the ATM protocol (I believe Frame Relay and S25 also allow this). So, for example, to connect two computers across a company's network.
[For a more complete definition see ref]

The important thing about this connection is that it is set up at the request of one party - and then messages flow across the network to configure the route. This is as opposed to a PVC (permanent virtual circuit) where the connection is configured manually at each intermediate computer/router along the way (and os in the event of an intermediate router/computer being removed the connection is lost and must be set up again manually.

FYI There is also the concept of an SPVC where each end of the connection is set up manually, but the middle part is set up dynamically - this gives the advantage of the SVC connection, while not requiring the two endpoints to support the full connection protocol.
