Can the BERT pattern be used at data rates above 14.4 Kbps?

The ITU document O.153 paragraph 2.1 indicates the BERT pattern can be used at data rates up to 14.4 Kbps. However, the Sealevel WinSSD utility allows the BERT pattern to be used at all available data rates and supported communication modes, including those above 14.4 Kbps.
