Back to Back Frames
If two or more frames should be transmitted in a high speed sequence without interframe time
fill, the transmission sequence according figure 34 has to be used.
This means that the closing flag will be immediately followed by an opening flag. The HSCX
receiver, however, is capable of receiving frames separated by only one (shared) flag.
