3.4.2 Data Terminal Parameters
Transmit Data Clock Synchronisation.
For each digital interface, the 64kbps transmitted data may be synchronised to one of
three options. These are:
1) Sync to Rx: Synchronise to clock from incoming data: (slave operation),
2) Ext sync clock: Synchronise to external network clock (external clock operation,
3) Internal Ref: Synchronise to EX7100 internal clock (master operation).
The selection made will depend on the equipment being connected to the EX7100
terminal. Setting the clock synchronisation to ‘Sync to Rx’ will suit most applications that
use external equipment as the clock source (Exicom factory default setting).
Note: The six channel version of the EX7100 uses automatic internal synchronisation,
and does not need to be configured.
