LMI
A means of providing access to the Frame Relay network over a DSL connection
Frame Relay is a packet-switching technology. It works by sending information in packets, which are called frames, through a shared frame-relay network.
Serial interfaces do not pass any MAC information because the information is formed using WAN encapsulation (PPP. HDLC, Frame Relay).
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.

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.
