27.3 OC3 Mode
This section contains various scenarios with which the Supermapper can be used in the OC3 mode. The diagram
preceeeding each script shows the data path and the different blocks that are used in this path. Please note that
this is to be used only as a guideline for the design.
27.3.1 OC3CDRLOOPBACK
Note: The transducer converts the optical signal to electrical signals and vice-versa.
