Model 3120 RAS Administrators’ Reference Guide Introduction Frame Relay is a high-speed datalink communications technology that is used in hundreds of networks throughout the world to connect LAN, SNA, Internet, and voice applications. Within the network, Frame Relay uses a simple form of packet switching that provides high throughput and reliability. (For more informa- tion, refer to the Frame-Relay MIB: 1315 Management Base for Frame Relay DTEs.)

The signaling is slightly different depending on which end of the Frame Relay Interface it is, or in other words its orientation. The User end issues periodic STATUS ENQUIRY messages and waits for a STATUS reply from the Network.
