PERFORMANCE STATISTICS Menu Screens
The Performance Statistics screens are used to view the stored
T1 performance statistics. To reach this screen from the MAIN
menu, type <P>. The example screen below (Figure 18), shows
various performance parameters for both the NET-to-CPE (A
to Z) and CPE-to-NET (Z to A) directions as well as a status reg-
ister describing abnormal circuit conditions during the period.
By using the selection keys at the bottom of the screen, all His-
torical time registers can be examined. Type the appropriate
command to view the 15-minute, Hourly, and Daily screens or
the <N> for Next and <P> for Previous page commands. The
parameters on these screens are automatically updated at 5-sec-
ond intervals. To return to the MAIN menu from this screen,
press the <Esc> key.

Event/Alarm Log Screen
9.2.5.1
The Event/Alarm Log screen is used to view various
events that occurred on the span during the monitoring period.
The log provides time-stamped entries for the most important
types of events such as alarm signal detection, loopback, PM
Registers cleared, Event/Alarm Log cleared, Clock setting, loss
of signal, power outages, and more. The Event/Alarm Log will
retain the 200 most recent events in non-volatile memory. The
Event/Alarm Log can be viewed locally via the craft interface
port. An example of a typical Event/Alarm Log screen is shown
