HFC-E1
➌ PCM-to-E1
➍ multiple FIFOs to E1
8
Hint: Here it is possible to occupy HFC-channels that are assigned to E-channels (HFC-channel[3, 7, 11, . . . , 31])
The PCM-to-E1 connection blocks two FIFOs
these FIFOs, they must be enabled to switch on the data transmission between the PCM
and the E1 interface.
Finally, the bidirectional connection between two FIFOs and one E1 time slot com-
pletes the example.
