The active high transmit line alarm indication
signal (TLAIS) controls the insertion of line AIS
in the outgoing stream when the ring control
port is disabled. When TLAIS is set high, the
complete frame (except the section overhead
or regenerator section) is overwritten with the
all ones pattern (before scrambling). The
TLAIS input takes precedence over the TTOH
and TTOHEN inputs. TLAIS is sampled on the
rising edge of TICLK.
The transmit ring control port data (TRCPDAT)
signal contains the transmit ring control port
data stream 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). The transmit ring control
port data consists of the filtered K1, K2 byte
values, the change of APS value bit position,
the protection switch byte failure status bit
position, the send AIS and send RDI bit
positions, and the line REI bit positions.
TRCPDAT is normally connected to the
RRCPDAT output of a mate STXC in ring-
based add-drop multiplexer applications.
TRCPDAT is sampled on the rising edge of
TRCPCLK.
The transmit section DCC clock (TSDCLK) is a
192 kHz clock used to sample the TSD input.
TSDCLK is generated by gapping a 216 kHz
clock.
The transmit section DCC (TSD) signal
contains the section data communications
channel (D1, D2, D3) inserted into the outgoing
stream. The TTOHEN input takes precedence
over TSD. TSD is sampled on the rising edge
of TSDCLK.
