Function
The DS3 transmit data (DS3TDAT[3:1]) signals
contain the DS3 streams to be mapped into the
SONET/SDH SPE. DS3TDAT[1] corresponds
to the STS-1 (STM-0/AU3) #1 stream of an
STS-3 (STM-1/AU3) while DS3TDAT[3]
corresponds to the STS-1 (STM-0/AU3) #3
stream of an STS-3 (STM-1/AU3).
DS3TDAT is sampled using the rising or falling
edge of DS3TICLK as selected using the
DS3TICLKB bit in the SPECTRA-155 Clock
control register.
Reserved. Should be strapped low in this mode
of operation.

Reserved.
The DS3 transmit AIS (DS3TAIS[3:1]) signals
force the assertion of DS3 AIS. When
DS3TAIS is high, DS3 AIS is inserted on the
corresponding DS3TDAT input. DS3TAIS[1]
corresponds to the STS-1 (STM-0/AU3) #1
stream of an STS-3 (STM-1/AU3) while
DS3TAIS[3] corresponds to the STS-1
(STM-0/AU3) #3 stream of an STS-3
(STM-1/AU3).
DS3TAIS is sampled using the rising edge of
DS3TICLK.
