Error Acronym Description Error Acronym Description
CV-L Code Violation - Line
Total BPV count. SES-P Severely Errored Seconds - Path
Seconds with SEF or CRC (ESF) ≥ 320 or
FE (d) (SF) ≥ 8 (FT + FS).
ES-L Errored Seconds - Line
Seconds with BPV ≥ 1. UAS-P Unavailable Seconds - Path
A second of unavailability based on SES-P
or AIS ≥ 1.
SES-L Severely Errored Seconds - Line
Seconds with BPV plus EXZ ≥ 1544 or
LOS ≥ 1.
PRM-NE (a)
(a) Only displays on H2TU-R Performance History screens.
Performance Report Monitoring - Near End
The PRM from CPE indicates errors, and
the signal received from the network at the
remote is error-free.
UAS-L Unavailable Seconds - Line
Seconds with LOS ≥ 1. PRM-FE (a) Performance Report Monitoring - Far End
The PRM from the network indicates
errors, and the signal received from the
CPE is error-free.
PDVS-L Pulse Density Violation Seconds - Line
Seconds with excessive zeroes
(AMI = 16 zeroes, B8ZS = 8 zeroes).
B8ZSS (b)
(b) Displays on the DS1 Current Statistics screens.
B8ZS Monitored Seconds
Seconds with B8ZS detection when AMI
option is active.
ES-P Errored Seconds - Path
Seconds with SEF (c), CRC( ESF), or
FE (d) (SF) ≥ 1.
(c) 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.
(d) FE is a frame bit error.
MSEC (b) Monitored Seconds of the current
(15minut e/1 hour/1 day) screen.
