Function

TLAIS/

Input

D17

The active high transmit line alarm indication signal

(TLAIS) controls the insertion of line AIS in the

transmit outgoing stream when the ring control port

is disabled. When TLAIS is set high, the complete

frame (except the section overhead or

line/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 TCLK.

TRCPDAT

The transmit ring control port data (TRCPDAT)

signal contains the transmit ring control port data

stream when the ring control port is enabled. The

transmit ring control port data consist of the send

line AIS, the send line RDI bit positiions and the line

REI bit positions.TRCPDAT can be connected

directly to the RRCPDAT output of a mate

SPECTRA-622 in ring-based add-drop multiplexer

applications.

TRCPDAT is sampled on the rising edge of

TRCPCLK.

The enabling and disabling of the ring control port is

controlled by the RCPEN bit in the SPECTRA-622

Ring Control register.
