18.17. EXCHANGE SYNCHRONISATION WITH NETWORK CLOCK
C-DOT MAX-XL exchange with NSC-AO1 Card (Level 2 clock) in SCU frame of
CM-XL supports network synchronisation with TAX clock or higher order atomic
clock.
In this case, data transfer rate through modems yields very good throughput in case
of inter-exchange data calls.
Synchronisation of the exchange with TAX Clock is done as shown in Fig. 18.2.
