frames.
Frame Relay Aware. Said of an access unit that can read the frame relay header and route
the data internall to the correct port.
Internet Protocol. An open networking protocol used for internet packet delivery.
Integrated Services Digital Network. Telecommunication service that uses digital
transmission and switching technology to provide voice and digital data communications
on a bearer channel (B-channel) while sending signaling on the data channel (D-channel).
