Frame Relay assembler/disassembler

This article is about the telecommunications device. For for the library model, see Functional Requirements for Authority Data.

FRAD (Frame Relay Access Device or Frame Relay Assembler/Disassembler) is a device that turns data packets into frame relay frames that can be sent over Frame Relay network and turns the received Frame Relay frames into data packets. Its assembly/disassembly functionality is similar to a PAD or Packet Assembler/Disassembler, which is used for accessing X.25 networks.

For a cooperative user system, the level of the cooperation of the users directly determine the ultimate performance. How to make the users feel natural and barrierfree is a problem of designing a face recognition system. A good design of the face recognition system could substantially not only improves the practical application performance, but also enhances the users’ satisfaction with the system. The design of a cooperative user system are mainly related to the following questions: how to cover most of the user’s height, how to get frontal face images, and how to capture high-quality images.
