E1 Clock synchronization
As from Hardware Version 6.01, the
CPU is equipped with an external
clock synchronization input. This
enables synchronization with an
external transmission technology
clock. The default settings can be
used for the most common
applications. If required, adaptations
can be made for line length, signal
type and impedance.
