PROCESSOR-BASED SIGNALING
Many robbed-bit signaling applications utilize a micro-
processor to insert transmit signaling data into the out-
going data stream. The circuit shown in Figure 23 “de-
couples” the processor timing from that of the DS2180A
by use of a small FIFO memory. The processor writes to
the FIFO (six bytes are written: three for A data, three for
B data) only when signaling updates are required. The
system is interrupt-driven from the transmit multiframe
sync input; the processor must update the FIFO prior to
Frame 6 (625
μ
s after interrupt) to prevent data corrup-
tion. The application circuit shown supports 193S fram-
ing. Additional hardware is required for 193E applica-
tions.
