Alarms
ERDI-VPD / LP-ERDI-PD (Enhanced Remote Defect Indication -
Payload Defect) for SONET/SDH, indicates that bits 5, 6, and 7 of the Z7
(SONET) / K4 (SDH) byte contain the “010” pattern, and bit 8 of the V5
byte contain “0”, in five consecutive VT/LP superframes. In TX,
generates a “010” pattern for bits 5, 6, and 7 of the Z7 (SONET) / K4
(SDH) byte, and “0” for bit 8 of the V5 byte.
ERDI-VSD / LP-ERDI-SD (ERDI - Server Defect) for SONET/SDH,
indicates that bits 5, 6, and 7 of the Z7 (SONET) / K4 (SDH) byte contain
the “101” pattern, and bit 8 of the V5 byte contain “1”, in five
consecutive VT/LP superframes. In TX, generates a “101” pattern for
bits 5, 6, and 7 of the Z7 (SONET) / K4 (SDH) byte, and “1” for bit 8 of
the V5 byte.
ESMC Loss for SyncE, indicates that no ESMC valid information frames
were received for more than 5 seconds.
Exc. Skew (Excessive Skew) indicates that the skew exceeds the
defined threshold.
Skew Alarm Threshold (bits) for Ethernet test applications, allows
setting the threshold value that will be used to declare a skew alarm.
Not available at 100G when the RS-FEC check box is selected. Default
restores the default skew alarm threshold value.
