Control Word Support

Martini draft encapsulation includes a control word with the following fields:

T bit for transport type
E bit for explicit forward congestion indication (EFCI)
C bit for cell loss priority (CLP)=1 indication
U bit for command/response indication based on AAL5 common part convergence sublayer user-to-user indication (CPCS-UU)
Optional sequence number

The current JUNOSe implementation supports the T bit and optional sequence number fields.
