The Transmit Bipolar E3 Stream diagram (Figure 47) illustrates the generation of a bipolar E3
stream. The HDB3 encoded E3 stream is present on TPOS and TNEG. These outputs, along with
the transmit clock, TCLK, can be directly connected to a E3 line interface unit. Note: TCLK is a
flow through version of TICLK; a variable propagation delay exists between these two signals.

The Transmit Unipolar E3 Stream diagram (Figure 48) illustrates the unipolar E3 stream
generation. The ATM cell stream, along with valid E3 overhead bits is contained in TDATO. The
TOHM output shown marks the G.832 frame boundary (the first bit of the FA1 frame alignment
byte) in the transmit stream. Note: TCLK is a flow through version of TICLK; a variable
propagation delay exists between these two signals.
