DML header: none, Codec2 does not have codec specific data.
DML data packet:
|0 - 7||8 - 15||16 - 23||24 - 31||32 - 39||40 - 47||48 - 55||56 - 63||64 -|

|48 bit address||8 bit Codec2 mode||8 bit Level||Codec2 data octets|
Mode 65 is used for A-Law encoding. This is not an actuall codec2 mode. However it is usefull if the sending node has no practical bandwidth limit and the data is not already encoded.
The signal level is encoded in a single byte. values 1 through 255 represent levels -127dBm through 0dBm. (Zero is regarded as -Infinite dBm)
