Error
Description
Acronym
CV-L Code Violation - Line
Total BPV count.
ES-L Errored Seconds - Line
Seconds with BPV ≥ 1.
SES-L Severely Errored Seconds - Line
Seconds with BPV plus EXZ ≥ 1544 or
LOS ≥ 1.
UAS-L Unavailable Seconds - Line
Seconds with LOS ≥ 1.
CV-P Code Violation - Path
Total count of FE errors for SF or CRC-6
errors for ESF.
ES-P Errored Seconds - Path
Seconds with SEF
FE (SF) ≥ 1.
(a) FE is a frame bit error.
(b) Only appears on H2TU-R Performance History screens.
(c) Appears on the DS1 Current Statistics screens.
(d) Severely Errored Frame—Two or more frame bit errors occurring in a 0.75 ms interval for SF or a 3 ms interval for ESF.
(e) Only appears on the H2TU-R Blockage Indicator (BI) History screen.

Description
Severely Errored Seconds - Path
Seconds with SES, CRC (ESF) ≥ 320, or
(SF) ≥ 8 (F
(a)
FE + F ).
T S
Unavailable Seconds - Path
A second of unavailability based on SES-P or
AIS ≥ 1.
(b)
Performance Report Monitoring - Near End
The PRM registers in the ESF/FDL from CPE indicate errors,
and the signal received from the network at the remote is
error-free.
(b)
Performance Report Monitoring - Far End
The PRM registers in the ESF/FDL from the network indicate
errors, and the signal received from the CPE is error-free.
(c)
B8ZS Monitored Seconds
Seconds with B8ZS detection when AMI option is active.
(c)
Monitored Seconds of the current (15-minute/1-hour/1-day)
screen.
Blockage Indicator (BI) = [(0.2 x ES + 0.4 x SES + UAS)/
MSEC] x 100% (MSEC is the same as the DS1 MSEC)
