E1 interfaces.
CRC4 – Cyclic redundancy check indicate errored submultiframes received on the E1 side.
E-Bit – CRC4-indication bit denoting received errored submultiframes received on the E1 side.
FAS – Errored frame alignment signal received on the E1 side.
Errored Block (EB) – A block in which one or more bits are in error.
Errored Second (ES) – A second period with one or more errored blocks or at least one defect.
Severely Errored Second (SES) – A second period, which contains more than 805 errored blocks
per second (if CRC4 options are enabled) or the number of errored framed alignment is more
than 28 per second. SES is a subset of ES.
Background Block Error (BBE) – An errored block not occurring as a part of SES.
Errored Second Ratio (ESR) – The ratio of ES to total seconds in available time during a fixed
measurement interval.
Severely Errored Seconds Ratio (SESR) – The ratio of SES to the total number of error-free
seconds in available time during a fixed measurement interval.
Background Block Error Ratio (BBER) – The ratio of BBE to the total number of error-free seconds
in available time during a fixed measurement interval.
Available time – The period when measurements of the parameters are possible.
Unavailable time – The period when the measurements of the parameters are impossible.
