Performance History at the DS1 Interface

Figure 13 is an example of an H2TU-R 31-day DS1 performance screen as viewed from the line unit. In addition,
there are 48-hour, 25-hour, and current statistic screens for the DS1 interface for the H2TU-R as well as the
H2TU-C. Table 12 describes the acronyms used in the performance history screens.

(a)
FE
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 from CPE indicates errors, and the signal
received from the network at the remote is error-free.
(b)
PRM-FE Performance Report Monitoring - Far End
The PRM from the network indicates 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.
(c)
BI BI = [0.2 x ES + 0.4 x SES + UAS)/ MSEC] x 100%
(MSEC is the same as the DS1 MSEC)
