5.2.3.10 CSU Line Performance Statistics
The integrated CSU detects, organizes, and stores CSU line performance statistics in industry-
standardized formats. You can use this data to identify existing line problems as well as monitor for
developing problems.
Note: CSU statistics are only available when the CM-5RB module is operating in ESF mode. Section
4.2.2 - Display and Change Items in Basic Configuration Group and Table 4-8 give information
on verifying the CM-5RB module's frame format.
CSU Line Performance Statistics Standard Selection
CSU line performance statistics can be presented in either of two industry formats: ANSI T1.403-
1995 or AT&T TR54016. The integrated CSU's factory default standard is ANSI. Use the
Configuration Group to select the integrated CSU's standard.
1. Press down repeatedly on the GROUP switch until the display reads TSEL.
2. Press down repeatedly on the SET/NEXT switch until the display reads CSU. Notice that CSU is
underscored, indicating an additional subgroup.
3. Press up once on the SET/NEXT switch to display Off, the first of three CSU options.
4. Press down repeatedly on the SET/NEXT switch until the display shows the standard you want
to select.
5. To change modes, press up twice on the SET/NEXT switch. After the first press the green (top)
light blinks, indicating that a change is about to be made. After the second press, it turns on
continuously, indicating that the integrated CSU is now operating in the standard you selected.
CSU Line Performance Statistics Access and Evaluation
You can determine the performance status of an ACS-160 Series or STL-160 Series multiplexer by
issuing one of the four ISiCL commands to its TERM, DI-A, or DI-B module. Table 5-19 describes
the four commands. Figure 5-18 shows the relationship of the CSU line performance data
commands to local and remote multiplexers.
