Question 3

What is a FRAD? What is it used for?

Accepted Answer

A FRAD, or frame relay assembler/disassembler is a device that connects the customer's LAN to a frame relay network. It is often a module in a router, switch, or chassis hub. It is responsible for encapsulating (assembling)packets and de-encapsulating (disassembling)frame relay formatted data.
