| MultiRate configuration element from the Assignment Command message. |
| Example: 28111a40. |

| If "Voice boundary detection" is enabled, then only bursts are decoded as voice where |
| |
| - the framenumber is greater then the framenumber of a received "Connect" or "Connect Acknowlegde" message, and |
| - the framenumber is less then the framenumber of a "Release" message |
