EXFO FTB-8510B Guia Del Usuario página 1005

ERDI-CD (Enhanced RDI - Connectivity Defect): The ERDI-CD alarm is
declared when bits 5, 6, and 7 of the K4 byte contain the "110" pattern,
and bit 8 of the V5 byte contain "1", in five consecutive LP superframes.
ERDI-PD (Enhanced RDI - Path Payload Defect): The ERDI-PD alarm is
declared when bits 5, 6, and 7 of the K4 byte contain the "010" pattern,
and bit 8 of the V5 byte contain "0", in five consecutive LP superframes.
Note: Refer to Alarm/Error Measurements on page 47 for H/C LEDs, and Seconds
information.
J2 Trace
Received Message: Displays the J2 value in 16-bytes or 64-bytes
format. The <crc7> represents the CRC-7 for a 16-bytes format. The
last two bytes of a 64-bytes format, <C
respectively a carriage return and a line feed.
Enable LP-TIM (Low Order Path - Trace Identifier Mismatch): Allows
enabling the Trace Identifier Mismatch for the expected message
defined. Enable LP-TIM has to be enabled to give access to the
expected trace format and message. When Enable LP-TIM is disabled,
the J2 1-byte is available from the LOP OH TX/RX (SDH) on page 356.
Expected Message: Allows entering the message that is expected. J2
value should be ASCII suitable characters. The default message is
EXFO SONET/SDH for 16 bytes and EXFO SONET/SDH Analyzer high
order path trace test message for 64 bytes. However, with VCAT/LCAS
the default message will be EXFO followed by the VCG number (VCAT
and LCAS) and the SQ (VCAT only) number (for example
EXFO-VCG1-SQ0) for both 16 and 64 bytes formats.
Expected Format: Allows the selection of the format expected.
Choices are 16 or 64 bytes. The default setting is 16 bytes.
