Description
Acronym
UAS-P Unavailable Seconds - Path
A second of unavailability based on SES-P or
AIS ≥ 1.
(b)
PRM-NE 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)
PRM-FE 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)
B8ZSS B8ZS Monitored Seconds
Seconds with B8ZS detection when AMI option is
active.
(c)
MSEC Monitored Seconds of the current
(15-minute/1-hour/1-day) screen.
(f)
BI Blockage Indicator (BI) = [(0.2 x ES + 0.4 x SES +
UAS)/ MSEC] x 100% (MSEC is the same as the
DS1 MSEC)
