| Parameter | Definition |
|---|---|
| MS-EB | Multiplex Section Errored Block (MS-EB) indicates that one or more bits are in error within a block. |
| MS-ES | Multiplex Section Errored Second (MS-ES) is a one-second period with one or more errored blocks or at least one defect. |
| MS-SES | Multiplex Section Severely Errored Second (MS-SES) is a one-second period which contains 30 percent or more errored blocks or at least one defect. SES is a subset of ES. For more information, see ITU-T G.829 Section 5.1.3. |
| MS-BBE | Multiplex Section Background Block Error (MS-BBE) is an errored block not occurring as part of an SES. |
| MS-UAS | Multiplex Section Unavailable Seconds (MS-UAS) is a count of the seconds when the section was unavailable. A section becomes unavailable when ten consecutive seconds occur that qualify as MS-SESs, and it continues to be unavailable until ten consecutive seconds occur that do not qualify as MS-SESs. When the condition is entered, MS-SESs decrement and then count toward MS-UAS. |
| MS-FC | Count of the number of occurrences of near-end failure events, and is incremented by one each time a near-end failure event begins. Failure counts are incremented during unavailable time. |
| MS-ESR | Multiplex Section Errored Second Ratio (MS-ESR) is the ratio of errored seconds to total seconds in available time during a fixed measurement interval. |
| MS-SESR | Multiplex Section Severely Errored Second ratio (MS-SESR) is the ratio of SES to total seconds in available time during a fixed measurement interval. |
| MS-BBER | Multiplex Section Background Block Error Ratio (MS-BBER) is the ratio of BBE to total blocks in available time during a fixed measurement interval. The count of total blocks excludes all blocks during SESs. |
| MS-PSC-W | For a working line in a 2-fiber MS-SPRing, Multiplex Section Protection Switching Count-Working (MS-PSC-W) is a count of the number of times traffic switches away from the working capacity in the failed line and back to the working capacity after the failure is cleared. MS-PSC-W increments on the failed working line and MS-PSC increments on the active protect line. For a working line in a 4-fiber MS-SPRing, MS-PSC-W is a count of the number of times service switches from a working line to a protection line plus the number of times it switches back to the working line. MS-PSC-W increments on the failed line and MS-PSC-R or MS-PSC-S increments on the active protect line. |
| MS-PSD-W | For a working line in a two-fiber MS-SPRing, Multiplex Section Protection Switching Duration-Working (MS-PSD-W) is a count of the number of seconds that service was carried on the protection line. MS-PSD-W increments on the failed working line and MS-PSD increments on the active protect line. |
| HP-EB | High-Order Path Errored Block (HP-EB) indicates that one or more bits are in error within a block. |
| HP-ES | High-Order Path Errored Second (HP-ES) is a one-second period with one or more errored blocks or at least one defect. |
| HP-SES | High-Order Path Severely Errored Seconds (HP-SES) is a one-second period containing 30 percent or more errored blocks or at least one defect. SES is a subset of ES. |
| HP-BBE | High-Order Path Background Block Error (HP-BBE) is an errored block not occurring as part of an SES. |
| HP-UAS | High-Order Path Unavailable Seconds (HP-UAS) is a count of the seconds when the VC path was unavailable. A high-order path becomes unavailable when ten consecutive seconds occur that qualify as HP-SESs, and it continues to be unavailable until ten consecutive seconds occur that do not qualify as HP-SESs. |
| HP-FC | Count of the number of occurrences of near-end failure events, and is incremented by one each time a near-end failure event begins. Failure counts are incremented during unavailable time. |
| RS-EB | Regenerator Section Errored Block (RS-EB) indicates that one or more bits are in error within a block. |
| RS-ES | Regenerator Section Errored Second (RS-ES) is a one-second period with one or more errored blocks or at least one defect. |
| RS-SES | Regenerator Section Severely Errored Second (RS-SES) is a one-second period which contains 30 percent or more errored blocks or at least one defect. SES is a subset of ES. |
| RS-BBE | Regenerator Section Background Block Error (RS-BBE) is an errored block not occurring as part of an SES. |
| RS-ESR | Regenerator Section Errored Second Ratio (RS-ESR) is the ratio of errored seconds to total seconds in available time during a fixed measurement interval. |
| RS-SESR | Regenerator Section Severely Errored Second Ratio (RS-SES) is the ratio of SES to total seconds in available time during a fixed measurement interval. |
| RS-BBER | Regenerator Section Background Block Error Ratio (RS-BBE) is the ratio of BBE to total blocks in available time during a fixed measurement interval. The count of total blocks excludes all blocks during SESs. |
| RS-UAS | Regenerator Section Unavailable Second (RS-UAS) is a count of the seconds when the regenerator section was unavailable. A section becomes unavailable when ten consecutive seconds occur that qualify as RS-UASs, and it continues to be unavailable until ten consecutive seconds occur that do not qualify as RS-UASs. |
