Pin Description
Transmit Ring Port Clock Input: This signal is connected to the RXRING-
LVTTL-5sd CLK output of a mating SONET/SDH framer. TXRINGD is clocked into the
SONET/SDH framer on the rising edge of this 19.44 MHz clock.

Transmit Ring Port Data Input: A serial input that is connected to a mating
SONET/SDH framer’s RXRINGD signal to allow communication of the
debounced K1, K2 and K3 bytes, Path REI and 3-Bit Path RDI, Line RDI
LVTTL-5sd and Line REI, New K3 Indication, and New APS Indication for all four
STM-1/STS-3cs or STM-4c/STS-12c to facilitate Ring mode operation. The
data on this pin is clocked into the SONET/SDH framer on the rising edge of
the TXRINGCLK signal.

Receive Ring Port Data Output: A serial output that provides the
debounced K1, K2, and K3 bytes, Path REI and 3-Bit Path RDI, Line RDI
and Line REI, New K3 Indication, and New APS Indication for all four
LVTTL-5sd STM-1/STS-3cs or STM-4c/STS-12c to facilitate Ring mode operation. A
start sequence and an address field is used to delineate the information
contained on this signal output. RXRINGD is output on the falling edge of
RXRINGCLK.
