Data lead time

Data lead-time means the time which is needed to transfer the data from the incoming 2M data interface of ACL2i to the outgoing 2M data interface of DNT2Mi-fp at the other end of the line.

The lead-time of the data from ACL2i to DNT2Mi-fp depends on the line rate selected as follows:
