Notes:
Clock from E13 is at 51.84 MHz rate and is not gapped. TXDATAEN is the combination of an internal clock enable and data enable from SPEMPR.
TXDATAEN is used to mark the overhead time and control bits time of the E3 frame. Clock enable is used to gap the clock rate to 34.368 MHz.
C11’s (the first C bit of the first tributary) position is optionally marked by TXSYNC, which is provisioned to be 0 to 255 bits before C11 (bit 385 of the E3
frame).
During periods where the OH is present, the TXDATAEN signal goes low.
All C bits are zero and the stuff bits are used for data.
