ASMi-54C LRS-102 Ver. 2.0 Monitoring Performance 4-3
The parameters displayed on the screen are explained in Table 4-1 . Note that the
information regarding the SHDSL Rate, Current Noise Margin, Current Loop
Attenuation, and Current Power Backoff parameters can be displayed only when
the SHDSL line is in the Data state (that is, after a successful activation: in other
states, ignore these fields - they display 0 to indicate that the displayed values
are irrelevant).
Table 4-1. SHDSL Line Status Parameters
Parameter Description
Administrative
Status
Displays the administrative status of the line: Up or Down
SHDSL State Displays the current line state:
• PreActivation – the SHDSL line waits to start the activation process
• Activation – the SHDSL line performs the activation process
• Data – the SHDSL line completed the activation process and is now carrying data. In
this case (Data) the following fields display the values listed below. Otherwise they
dispay 0.
SHDSL Rate Displays the current line rate, in kbps
Current Noise
Margin
Displays the currently estimated noise margin at the local endpoint, in dB
Current Loop
Attenuation
Displays the currently estimated loop attenuation at the local endpoint, in dB
Current Power
Backoff
Displays the current power backoff value at the local endpoint, in dB
Displaying SHDSL Line Performance Monitoring Statistics
³ To display the SHDSL line performance monitoring statistics for the current
15-minute interval:
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 Statistics > Current (15 min). You will see the current 15-minutes
statistics screen for the selected SHDSL line.
The displayed parameters are explained in
Table 4-2 .
Table 4-2. SHDSL Line Statistics Parameters – Current 15-Minute Interval
Parameter Description
Current ES Displays the number of SHDSL errored seconds (ES) on this end point in the current
interval.
An SHDSL ES is a second during which one or more CRC anomalies are declared,
and/or one or more LOSW defects are declared
