1 = Group is established and a round-robin is created
0 = Group is not established
1 = certain LSM transitions (Usable → Active) are allowed
0 = certain LSM transitions (Usable → Active) are blocked
1 = Enables the link differential delay synchronization process
0 = disables the link differential delay synchronization process
This bit is used by the software driver to reset the differential delay in T1/E1 mode:
Reserved. Set to 0.
Sets the number of configured links within group.
Range: 0x0–0x7 (1–8 links in group)
