The level of this signal for shutdown depends on the transmitter used. The
SONET/SDH framer is programmed accordingly via the management inter-
face. In parallel mode, only TXSDOWN1 is used.

The supported data rates on RXSDAT1 are 155.52 and 622.08 Mb/s. An
external 100 Ω resistor is required as close as possible to the SONET/SDH
framer.
Serial SONET/SDH Receive Data 2: (0=true, 1=inverted)
The supported data rate on RXSDAT2-4 is 155.52 Mb/s. An external 100 Ω
resistor is required as close as possible to the SONET/SDH framer.

Parallel SONET/SDH Receive Data 1:
Byte-parallel input data from external SDH/SONET deserializer/demux, e.g.,
AMCC 3017. Bit 0 is the LSB. This data must be byte-aligned to the bytes in
the incoming SONET/SDH frame.
