Function

stream.

• The loss of pointer signal (LOP) indicates the

loss of pointer state in the corresponding STS-1

(STM-0/AU3), STS-3c (STM-1/AU4) or STS-

12c (STM-4-4c) SONET/SDH stream. LOP is

set high when invalid pointers are received in

eight consecutive frames, or if eight

consecutive enabled NDFs are detected in the

stream.

• The path alarm indication signal (PAIS)

indicates the path AIS state of the

corresponding STS-1 (STM-0/AU3) ), STS-3c

(STM-1/AU4) or STS-12c (STM-4-4c)

SONET/SDH stream. PAIS is set high when an

all ones pattern is observed in the pointer bytes

(H1 and H2) for three consecutive frames in the

stream.

• The path remote defect indication signal (PRDI)

indicates the path remote state of the

corresponding STS-1 (STM-0/AU3), STS-3c

(STM-1/AU4) or STS-12c (STM-4-4c)

SONET/SDH stream. PRDI is set high when

the path RDI alarm bit (bit 5) of the path status

(G1) byte is set high for five or ten consecutive

frames. The RDI10 bit in the RPOP Pointer

MSB register controls whether five or ten

consecutive frames will cause a PRDI

indication.

• The path enhanced remote defect indication

signal (PERDI) indicates the path enhanced

remote state of the corresponding STS-1 (STM-

0/AU3), STS-3c (STM-1/AU4) or STS-12c

(STM-4-4c) SONET/SDH stream. PERDI is set

high when the path ERDI alarm code (bits

5,6,7) of the path status (G1) byte is set to the

same alarm codepoint for five or ten

consecutive frames. The RDI10 bit in the RPOP

Pointer MSB register controls whether five or

ten consecutive frames will cause a PRDI

indication.
