The Transmit Bipolar J2 Stream diagram (Figure 49) illustrates the generation of a bipolar J2
stream. The B8ZS encoded J2 stream is present on TPOS and TNEG. These outputs, along with
the transmit clock, TCLK, can be directly connected to a J2 line interface unit. Note: TCLK is a
flow through version of TICLK; a variable propagation delay exists between these two signals.

frame alignment signal
The Transmit Unipolar J2 Stream diagram (Figure 50) illustrates the unipolar J2 stream
generation. The ATM cell stream, along with valid J2 overhead bits is contained in TDATO. The
TOHM output shown marks the J2 multi-frame boundary (the first frame-alignment bit of each J2
multi-frame) in the transmit stream. Note: TCLK is a flow through version of TICLK; a variable
propagation delay exists between these two signals.
