DS3 Line 9
CV-L Coding Violations 9
This parameter is a count of B3ZS bipolar violations (BPV) occurring over the
accumulation period. BPVs that are part of the zero substitution code are
excluded.
ES-L Errored Seconds 9
This parameter is a count of seconds containing one or more BPVs, or one or
more LOS (from the DSX-3) defects.
SES-L Severely Errored Seconds 9
This parameter is a count of seconds during which BPVs exceed 44 or one or
more LOS defects occur.
OC-1 Section Parameters 9
Performance Monitoring Enabling 9
Collection of section parameters for OC-1 interfaces are initiated when a slot is
equipped with a 27G-U OLIU circuit pack. Parameters continue to be available in
reports and generate appropriate TCAs until the 27G-U OLIU is removed and the
update command or the UPD/INIT button is pressed.
Severely Errored Frame Seconds (SEFS) 9
This parameter counts the number of seconds during which an OOF, LOS, or
OLIU circuit pack failure occurred. SEFSs are counted and thresholded
independently for each OC-1 interface.
OC-1 Line Parameters 9
Performance Monitoring Enabling 9
Collection of line parameters for OC-1 interfaces are initiated when a slot is
equipped with an 27G-U OLIU circuit pack. Parameters continue to be available in
reports and generate appropriate TCAs until the 27G-U OLIU is removed and the
update command or the UPD/INIT button is pressed.
