Network Performance Reports (NI PERF RPTS) The Network Interface Performance Reports display the user copy of the performance data. See Figure 4-2. The TSU 600 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. Use the scroll keys to access the complete display of the following report fields: 15 Minutes 24 Hours Data Values %AS % of available seconds %EF % of error free seconds ES Number of errored seconds (1 or more errors/second SES Number of severely errored seconds (more than 320 errors/second) UAS Number of unavailable seconds (10 or more consecutive seconds) Figure 4-2. Network Interface Performance Report 4-2 TSU 600 User Manual 61202076L1-1 Chapter 4. Status Menu If insufficient time has passed to collect data, NA displays. Continue with standard operating procedures to exit the display. When this menu is active, performance data can be cleared by pressing Clear (Shift 9) on the keypad. Only the user copy of the performance data is cleared. Since only the user’s copy of performance data is cleared by the TSU 600, the data displayed here might be different from the data sent to the network as PRM data. Network Interface Errors (NI ERRORS) The NI Errors submenu displays the types of errors the Network Interface (NI) detects. A blinking CSU error LED indicates that network errors are detected. The asterisk (*) above an item indicates the type of errors detected. The error types are as follows: CRC CRC-6 bit errors based on the FDL. This is valid only in ESF mode. BPV Bipolar violations. XS0 Excess zeros. FER Framing errors. 61202076L1-1 TSU 600 User Manual Chapter 4.
