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.
PRM-NE (c)
(c) Only appears on H2TU-R Performance History screens.
Performance Report Messaging - 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 (c) Performance Report Messaging - Far End
The PRM from the network indicates errors, and
the signal received from the CPE is error-free.
CV-P Code Violation - Path
Total count of FE errors for SF or CRC-6 errors
for ESF. B8ZSS (d)
(d) Appears on the DS1 Current Statistics screens.
B8ZS Monitored Seconds
Seconds with B8ZS detection when AMI option
is active.
ES-P (e)
(e) Path refers to the total framed payload being transported between two points.
Errored Seconds - Path
Seconds with SEF
(f) , CRC (ESF) or
FE (b) (SF)
≥
1.
(f) 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.
MSEC (d) Monitored Seconds of the current
(15-minute/1- hour/1-day) screen.
