AD33
RXSTFD0
TO
Receive OTU DW overhead stuff data output for the
drop path.
AE4
DROPOHCLK1
TO
DW overhead clock for the drop path overhead
insertion. This clock is used by the external FPGA to
transmit OTU DW overhead data (TXOCHD1), frame
sync (TXOCHFS1), and stuff bytes (TXSTFD1).

AA33
ADSDHOHCLK
TO
SONET/SDH overhead clock for the add path
overhead insertion and extraction. This clock is used
by the external FPGA to capture RX SONET/SDH
overhead data (ADRXSDHOHD) and frame sync
(ADRXSDHOHFS), and to insert TX SONET/SDH
overhead data (ADTXSDHOHD) using frame sync
(ADTXSDHOHFS).
