fax-on-demand (FOD)

datagrams, known as ATM frames, over an ATM infrastructure using SONET/SDH facilities. FAST is similar to Data Exchange Interface (DXI) and Frame User Network Interface (FUNI), which are designed for access to an ATM network over relatively low-speed plesiochronous transmission facilities. FAST, however, is designed for access and/or inter-switch trunking over very high speed SONET/SDH transmission facilities. See also ATM, ATM Forum, datagram, DXI, frame, FUNI, plesiochronous, SDH, and SONET.
