Asynchronous Transfer Mode allocates bandwidth on demand, automatically adjusting the network
capacity to meet the system needs. Fixed-length cells (53 octet) require lower processing overhead and
allow higher transmission speeds than traditional packet switching methods. ATM uses five octet headers
in each fifty-three octet cell to match cells with specific virtual channels to which they belong.

ROTOCOL
Copper Mountain Frame Relay is a data link layer protocol that uses Frame Relay instead of ATM on the
subscriber loop. Frame relay is a switched layer protocol that handles virtual circuits using High-Level
Data Link Control (HDLC) encapsulation. Frame Relay uses statistical multiplexing as opposed to
time-division-multiplexing many logical connections over a single physical link.
