1.3.25 The INV Indication

The Invalid Indication is sent to the DTE whenever the HSU Card receives an unknown or
syntactically invalid command.

1.3.26 Performance Data

The HSU-AD 5 35 Card supports proprietary end-to-end performance data for super-rate
circuits (Nx64 kbps or Nx56 kbps, minus 8 kbps). This mode is only available for users
transmitting data from one card (local) to another (remote). You can select between normal
operation (full bandwidth allocated to data traffic) and performance data monitoring, where 8
kbps of the total bandwidth is used for monitoring data traffic by selecting the perf setting as
the Loopback Generation Mode described earlier in the chapter.

Each one-hour reporting period is divided into 3600 seconds, and statistics are kept for the
current hour and the past 24 one-hour periods.

Figure 1-22 shows a typical Performance Data Screen, which is accessed by typing “p” (Perf
command) from the bottom highlighted line of the HSU Card Main Screen. Table 1-20 lists
the actions on the bottom line of the Performance Data Screen.
