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:
Table 6. 2 M data interface

Maximum allowed timing jitter at receiver
timing According to ITU-T G.823
Maximum generated timing jitter at
receiver timing According to ITU-T G.823
Frame structure According to ITU-T G.704
Relevant ETSI ONP standards ETS 300 246, ETS 300 247,
ETS 300 418, ETS 300 419
