Function

TLRDI

Input

The active high transmit line remote defect

indication (TLRDI) signal controls the insertion of

line RDI. Line RDI is inserted by transmitting the

code 110 (binary) in bit positions 6, 7, and 8 of the

K2 byte. This function can also be performed via

automatically upon detection of receive line AIS,

loss of signal, or loss of frame. The TLRDI input

takes precedence over the TTOH and TTOHEN

inputs. TLRDI is sampled on the rising edge of

GTOCLK.

TPAIS

Input

The active high transmit path alarm indication

(TPAIS) signal controls the insertion of STS-path

AIS. A high level on TPAIS forces the insertion of

an all ones pattern into the complete synchronous

payload envelope, and the payload pointer bytes

(H1, H2). Path AIS insertion is internally

synchronized to SPE frame boundaries. This

function can also be performed via register

access. TPAIS is sampled on the rising edge of

GTOCLK.

TPRDI

Input

The transmit path remote defect indication

(TPRDI) signal controls the insertion of path RDI.

A high level on TPRDI forces a logic one to be

inserted in the path RDI bit position in the path

status byte (G1). This function can also be

performed via register access, or be enabled to

occur automatically upon detection of receive line

AIS, loss of frame, loss of signal, loss of pointer,

or path AIS. The TPOH and TPOHEN inputs take

precedence over the TPRDI input. TPRDI is

sampled on the rising edge of GTOCLK.
