Hint: Here it is possible to occupy HFC-channels that are assigned to E-channels (HFC-channel[3, 7, 11, . . . , 31])
PCM-to-S/T
The PCM-to-S/T connection blocks two FIFOs
FIFOs, they must be enabled to switch on the data transmission between the PCM and the S/T
interface.
multiple FIFOs to S/T
Finally, the bidirectional connection between two FIFOs and one S/T-channel completes the
example.
