PROCESSOR-BASED TRANSMIT SIGNALING INSERTION Figure 23
PROCESSOR-BASED SIGNALING
Many robbed-bit signaling applications utilize a microprocessor to insert transmit signaling data into the
out-going data stream. The circuit shown in Figure 23 “decouples” the processor timing from that of the
DS2180A by use of a small FIFO memory. The processor writes to the FIFO (6 bytes are written: 3 for A
data, 3 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
s after
interrupt) to prevent data corruption. The application circuit shown supports 193S framing. Additional
hardware is required for 193E applications.
