Figure 50: Transmit Bipolar DS3 Stream
The Transmit Bipolar DS3 Stream diagram (Figure 50) illustrates the generation
of a bipolar DS3 stream. The B3ZS encoded DS3 stream is present on TPOS
and TNEG. These outputs, along with the transmit clock, TCLK, can be directly
connected to a DS3 line interface unit. Note that TCLK is a flow through version
of TICLK; a variable propagation delay exists between these two signals.
Figure 51: Transmit Unipolar DS3 Stream
TDAT
The Transmit Unipolar DS3 Stream diagram (Figure 51) illustrates the unipolar
DS3 stream generation. The TMFP output marks the M-frame boundary, X1 bit,
in the transmit stream. Note that TCLK is a flow through version of TICLK; a
variable propagation delay exists between these two signals.
