SONET/SDH TRANSPORT OVERHEAD TRANSCEIVER
Pin Name Pin Type Pin Function
No.
TRDI/
Input
TRCPFP
10 The active high transmit far end receive failure
(TRDI) signal controls the insertion of a far end
receive failure indication in the outgoing stream
when the ring control port is disabled. When
TRDI is set high, bits 6, 7, and 8 of the K2 byte
are set to the pattern 110. Line RDI may also
be inserted using the RDI bit in the TLOP
Control Register, or upon detection of loss of
signal, loss of frame, or line AIS in the receive
stream, using the AUTORDI bit in the Master
Control/Enable Register. The TRDI input takes
precedence over the TTOH and TTOHEN
inputs. TRDI is sampled on the rising edge of
TICLK.
The transmit ring control port frame position
(TRCPFP) signal identifies bit positions in the
transmit ring control port data (TRCPDAT)
when the ring control port is enabled (the
enabling and disabling of the ring control port is
controlled by a bit in the Master Control
Register). TRCPFP is high during the filtered
K1, K2 bit positions, the change of APS value
bit position, the protection switch byte failure bit
position, and the send AIS and send RDI bit
positions in the TRCPDAT stream. TRCPFP is
normally connected to the RRCPFP output of a
mate STXC in ring-based add-drop multiplexer
applications. TRCPFP is sampled on the rising
edge of TRCPCLK.
