| Minimal separation time between frames in ms. |

| Number of CF (Contiguous Frame) PDUs before next FC (Flow Control) |
| frame is sent. Zero value means all frames are sent consecutive |
| without an additional FC frame. |
| A BS counter at the sender counts from one to BS. When BS is reached, |
| the sender waits for a FC frame again an BS is reset. |
