Resetting the Performance Data Registers
The registers storing diagnostics data can be reset. To reset a register, bring
the register to display and press ENTER. To ensure that the collected data
remains meaningful and correlated after a specific register is reset, HCD-E1
will automatically perform the following actions.
For E1 Registers:
• When the CRC-4 function is enabled:
− Since the data collected for the current interval and for the current
24-hour interval is correlated, pressing ENTER while any of the
following CURR or L.TERM data items (ES, UAS, SES, BES, LOFC,
CSS, CURR SECS, CUR DEG MIN, LST DEG MIN, and L.TERM INT)
is displayed, clears all the performance diagnostics registers, not only
the one appearing on the display.
− Resetting the ERROR CRC register automatically resets the AV ERR
CRC register, and vice versa: resetting the AV ERR CRC register
automatically resets the ERROR CRC register.
• When the CRC-4 function is disabled, resetting the BPV COUNT register
automatically resets the BPV WORST register, and vice versa: resetting
the BPV WORST register automatically resets the BPV COUNT register.
For HDSL Registers:
When you press ENTER, all the HDSL performance registers that pertain to
the line whose number is displayed in the right-hand field of the top row are
simultaneously reset.
Displaying the
Performance Data
on a Control
Terminal
You can display the performance data on the control terminal by means of
the DSP SL PM, DSP R SL PM, DSP HDSL PM, and DSP R HDSL PM
commands, as explained in Chapter 4. By adding the /C switch to the
DSP SL PM and DSP R SL PM commands, you can reset the CRC ERROR
EVENTS and CRC AVG ERR EVENTS registers for the E1 sublink of the
appropriate (local or remote) unit. By adding the /CA switch to the
command, you can reset all the performance diagnostics registers.
