Payload Sub-block
The Payload sub block is activated by the cell mode frame pulse (cell mode) or DINxx_FP from FPGA (SONET
mode). A pulse on this signal indicates the start of a frame.
In SONET mode, only two types of data bytes are in each frame:
TOH bytes
SPE data bytes
There are N x 3 (N = 48) bytes of TOH per row and there are a total of 9 rows in a SONET frame. The rest of the
bytes in each row are SPE data bytes in SONET mode.
TOH Sub-block
This block is responsible formatting the 144 (48 x 3) bytes of TOH at the beginning of each row of the transport
frame. All TOH bytes may be transmitted transparently from the FPGA logic using the transparent mode. Alter-
nately, some or all TOH bytes may be inserted by the TOH block (AUTO_SOH and AUTO_TOH mode). The TOH
data is transferred across the FPGA/core interface as 32-bit words, hence 36 clock cycles (12 x 3) are needed to
transfer a TOH row. TOH insertion is controlled by software register bits as shown in the Register Map tables.
