4-2 Monitoring Performance ASMi-54C LRS-102 Ver. 2.0
When using the LRS-102 supervision utility, the ASMi-54C Ethernet physical
port performance monitoring functions are accessed after selecting the
desired module under Monitoring > Physical Layer > IO > Ethernet.
The collected data enables the system administrator to monitor the transmission
performance, and thus the quality of service provided to users, for statistical
purposes. In addition, when problems are reported by users served by ASMi-54C,
the collected data can be used for diagnostic purposes, because it can help
identify the source of the problem.
For SHDSL ports, the basic performance data is calculated for each second, and
accumulated and displayed over a 15-minute (900 second) interval. The data
accumulated for each interval, up to a maximum of 96 previous intervals (that is,
over the last 24-hour interval) is stored and can also be displayed. The oldest
interval is 1, and the most recent one is the interval with the largest number.
Only the data for the most recent 96 intervals is stored, and therefore the oldest
data is overwritten by new data. For SHDSL ports, data is also stored for up to
seven previous 24-hour intervals (that is, the last 7 days).
The performance statistics data is continuously collected, and is stored as long as
the equipment operates. The stored data is deleted when the ASMi-54C is reset
or removed, and is also lost when the LRS-102 is powered down.
Monitoring SHDSL Ports (Lines)
The physical layer performance monitoring data for SHDSL lines includes:
• Status data for each SHDSL line
• Statistics data. For each port, you can see:
 Current 15-minute interval
 A previous 15-minute interval within the last 24 hours, for which valid
performance data exists
 Current 24-hour interval
 A previous 24-hour interval within the last 7 days, for which valid
performance data exists.
The information displayed on the screen, which is accumulated continuously, is
automatically refreshed every few seconds.
You can clear the displayed statistics (that is, reset the displayed performance
monitoring counters) by selecting Clear Statistics. This ensures that only fresh
data is displayed, a useful feature during troubleshooting.
Displaying SHDSL Line Status
³ To display the SHDSL line status:
1. Navigate to the Monitoring > Physical Layer > IO screen, and then select the
I/O slot of the desired ASMi-54C module.
2. Select the SHDSL option.
3. Select the desired Line.
4. Select Status. You will see the Port Status screen for the selected SHDSL port.
