The frame relay line from your location connect directly to a frame relay switch, which switches frames (go figure) between connections. In practice, it's a lot like a huge VTP domain. Say you have sites A and B, with a PVC between them. You have a dedicated connection from each site to the provider (typically, two different CO owned or leased by the provider). The provider connects that link directly into a frame relay switch. The frame relay switch is programmed with the knowledge of what other frame relay switch connects to the remote side, or at least what the next hop is. This traffic is aggregated with other customers, which is why you get things like CIR and burst rates.
Therefore, you do not have a dedicated line (this isn't circuit-switching, thank goodness). But the magic all happens behind the scences, so we don't have to worry about it.
