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.

Header Error Control is located in the last (5th) byte of the ATM cell header that checks for cell integrity
only. The Coset polynomial is applied to the received HEC for comparison with the HEC generated
internally. HEC errors may be detected after synchronization any bit errors detected will prompt that cell
be dropped. The choice are
