Input Data Bus - Pin 4/Transmit DS3/E3 Overhead Indicator Output -
Channel 0 - Continued:
If the STS-1 Telecom Bus Interface (associated with Channel 0) has
been disabled - Continued:If the XRT94L31 is configured to operate
in the Clear-Channel DS3/E3 Framer over STS-3/STM-1 Mapper
Mode - Transmit DS3 Overhead Indicator - Channel 0 -
TxDS3OHInd_0 - Continued:
Therefore, whenever the System-Side terminal equipment samples the
TxDS3OHInd_0 output pin "High", then it must not apply the next pay-
load bit to TxDS3DATA_0 input pin.This output pin serves as a warning
that this particular payload bit is going to be ignored by the Transmit Sec-
tion of the Framer, and will not be inserted into payload bits, within the
outbound DS3 or E3 data stream.
