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 a PDU?
In networking, PDU means "protocol data unit", and it is the generic name of the "packets" of data used at different levels of the network. Using the numbering of the OSI layers: At layer 2, the PDUs are called "frame". Example: An Ethernet frame, a frame-relay frame. At layer 3, the PDUs are called "packets". Example: An IP packet. At layer 4, the PDUs are called "segments". Example: A TCP segment, a UDP segment.
What are the advantages of Frame Relay over x25?
Advantages of frame relay over x.25?Frame relay operates at a higher speed(1.544 mbps & currently 44.376mbps) By this it can easily be used instead of a mesh of T-1 or T-3 linesFrame relay operates in just the physical and data link layers. By this it is used as a back bone nwtwork to provide services to protoclols that already have a network layer protocol.It allows brusty data. in case of x.25 and t-line there is a fixed data rateFrame relay allows a frame size of 9000 bytes, which can accommodate all LAN framesFrame relay is less expensive than other traditional WAN
What are the Network operating system covered?
IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2),VLANs, Ethernet, access control lists (ACLs).
Is DSL a WAN data link encapsulation?
Frame relay and PPP is used with WAN encapsulation. Frame Relay most closely compares to the OSI data link layer (Layer 2). If you remember that the word "frame" describes the data link layer protocol data unit (PDU), it will be easy to remember that Frame Relay relates to OSI Layer 2. Like other data-link protocols, Frame Relay can be used to deliver packets (Layer 3 PDUs) between routers.
Which WAN technology operates at Layer 3 of the OSI model?
Which? Where are the Options?WAN Technologies operate & involve Layer1, Layer2 & Layer3 of OSI Model. Example of WAN Technology Protocols are Frame Relay, ATM & X.25 protocols.
Ford econoline flashers work but no turn signals?
Defective Flasher Relay, replace it. One relay operates the Hazard Lights and the other operates the turn signals. Be sure and replace the correct one.Defective Flasher Relay, replace it.

Which two items allow the router to map data link layer addresses to network layer addresses in a Frame Relay network?
LMI protocol, Invers ARP
What can X25 do the Frame Relay cannot do?
There are various differences between X.25 and Frame Relay. The most significant are: 1. Call Control X.25 connection establishment and release (call control) use in-band signaling within the same virtual channel used for user data transmission causing additional overhead. Frame Relay call control uses separate virtual channels identified by reserved DLCI using the LMI (Local Management Interface) protocol. 2. Routing vs. Switching X.25 performs packet switching on OSI layer 3 (network layer); Frame Relay performs packet switching on OSI layer 2 (data-link). Frame Relay does not use any layer 3 protocol. 3. Flow Control Frame Relay (FR) doesn't perform flow control between frame handlers (FR routers). X.25 routers have to acknowledge each frame; in case of frame errors frames have to be retransmitted and acknowledged. Frame Relay relies on flow control performed by higher layer protocols.Source: http://www.synapse.de/ban/HTML/P_LAYER2/Eng/P_lay264.html
What frame-relay command shows encapsulation type?
show frame-relay map
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.
