The Physical Layer and Transmission Errors
Rates of transmission errors are described by their probability of occuring, or by their expected bit-error-rate (BER). Transmission errors usually occur in bursts and are caused by:
Over a particular time interval,
a burst begins at the first bit that is corrupted (inverted),
and ends at the last bit corrupted -
the bits between are not necessarily all modified.
