1)NI PERF RPTS, Submenu of 1)STATUS
The Network Interface Performance Reports menu item displays the user copy of the performance
data. The T1 ESF CSU ACE maintains this performance data on the network in compliance with ANSI
T1.403 and AT&T document TR54016. The data displayed is data accumulated over the last 15
minutes and over the last 24 hours.

These fields cannot be edited, only cleared, as previously discussed. Only the user copy of the
performance data is cleared. The network management performance data history remains unaffected.
Separate carrier totals are kept which can only be retrieved and reset from the network.

The counters used in the performance screens are defined below.

Continue with standard operation procedures to exit the display.
Since only the user’s copy of performance data is cleared by the T1 ESF CSU ACE, the
data displayed here might be different from the data being sent to the network as
maintenance message data.
