Field Name Description
tiple bit error, and therefore, HEC Error Correction is not performed. [1],[2]
OCD Errors Total number of Out-of-Cell Delineation errors. ATM Cell delineation is the process
which allows identification of the cell boundaries. The HEC field is used to achieve
cell delineation. [4] An OCD Error is counted when the cell delineation process trans-
itions from the SYNC state to the HUNT state. [2]
LCD Errors Total number of Loss of Cell Delineation errors. An LCD Error is counted when at
least one OCD error is present in each of four consecutive overhead channel periods
and SEF (Severely Errored Frame) defect is present. [2]
Total Cells The total number of cells (OAM and Data cells) transmitted/received.
Data Cells The total number of data cells transmitted/received.
Bit Errors The total number of Idle Cell Bit Errors in the ATM Data Path. [3]
Total ES Total number of Errored Seconds. This parameter is a count of 1-second intervals
with one or more CRC-8 anomalies. [4]
Total SES Total number of Severely Errored Seconds. An SES is declared if, during a 1-second
interval, there are 18 or more CRC-8 anomalies in one or more of the received
bearer channels, or one or more LOS (Loss of Signal) defects, or one or more SEF
(Severely Errored Frame) defects, or one or more LPR (Loss of Power) defects. [4]
Total UAS
Total number of Unavailable Seconds. This parameter is a count of 1-second inter-
vals for which the xDSL line is unavailable. The xDSL line becomes unavailable at
the onset of 10 contiguous SESs. These 10 SES’s shall be included in the unavailable
time. Once unavailable, the xDSL line becomes available at the onset of 10 con-
tiguous seconds with no SESs. These 10 seconds with no SES’s shall be excluded from
unavailable time. [4]
