Frame Relay is a WAN (Wide Area Network) encapsulation protocol. It is considered a Multi-Access-Non-Broadcast medium. Each router has a DLCI number that will uniquely identify a specific route, however that DLCI is locally significant only. Data from your router will be sent into the Frame-Relay cloud, there the frames are switched (OSI layer 2). The path traveled is only there when it is needed. Your Service Provider might be switching towards MPLS though.

What frame-relay command shows encapsulation type?

How does frame relay work?
Frame Relay is a packet-switching technology. It works by sending information in packets, which are called frames, through a shared frame-relay network.
What is an updated and digital version of X25 that also relies on packet switching?
Frame relay.
Is Frame relay TDM?
no
What is Frame relay over DSL?
A means of providing access to the Frame Relay network over a DSL connection
Does ATM and frame relay has anything in common?
Both ATM and Frame Relay are ways to connect your local network router to an ISP
Does frame relay operate at layer 3 of the OSI model?
No. Frame Relay is not operating at Layer 3. Frame Relay is strictly a Layer 2 protocol suite, whereas X.25 provides services at Layer 3 (the network layer) as well. This enables Frame Relay to offer higher performance and greater transmission efficiency.
What is physical medium for frame relay?
its Digital
What are the functions frame relay?
