OVERLOAD FRAME
Like an error frame, an overload frame consists of two bit
fields: the overload flag and the overload delimiter. The bit
fields have the same length as the error frame field: six bits
for the overload flag and eight bits for the delimiter. The over-
load frame can only be sent after the end of frame (EOF)
field and in they way destroys the fixed form of the intermis-
sion field.
