1.3 Line Framing Functions
The CN8223 provides framers for DS3, E3 (both G.751 and G.832), E4 (G.832),
STS-1, and STS-3c/STM-1 formatted serial streams. The line receive circuitry
recovers the frame location from the serial stream and provides cell octets to the
physical layer block for cell delineation. The transmit circuitry receives cell octets
from the cell generation or physical layer blocks and adds line framing overhead
information as required. The LIU receive interface detects both Loss-of-Signal
(LOS) and Line Code Violations (LCVs). The active edge of the transmit output
clock is selectable.
Figure 1-2
illustrates the line framer functions of the CN8223.

STS-1, STS-3c, STM-1, DS3, E3, E4, TAXI
