ASMi-52L Installation and Operation Manual  Chapter 4 Configuration 
  Configuring the Physical Ports  4-15 
 
To configure the line probing: 
1.  From the SHDSL Port Configuration menu, select Line Prob. 
The display is refreshed and a new value appears. 
2. Select Save to save the changes. 
Configuring the Line Interface Type 
You can configure the ASMi-52L units with 4-wire interface to operate over 2-wire 
lines. Selecting the 2-wire operation mode disables pin 1 and pin 2 of the RJ-45 line 
connector. 
 
To configure the line interface type for ASMi-52L units: 
1.  From the SHDSL Port Configuration menu, select Configured wire 
The display is refreshed and a new value appears (2W or 4W). 
2. Select Save to save the changes 
3.  Reset ASMi-52L in order to active the change. 
Setting the Loop Attenuation Threshold 
Loop attenuation is difference (in dB) between the power transmitted from the 
ASMi-52L modem and the power received by the unit operating at the other side of 
the application. By setting the threshold, you instruct the modem to generate minor 
alarm (LOOP ATTN. OVER LINE A/B), if selected loop attenuation threshold value is 
exceeded. 
 
To set the loop attenuation threshold: 
1.  From the SHDSL Port Configuration menu, select Loop attenuation threshold. 
2.  Enter the desired value (0 dB to 127 dB). 
3. Select Save to save the changes. 
Setting the SNR Margin Threshold 
You can set signal-to-noise ratio threshold. ASMi-52L generates minor alarm (SNR 
MARGIN OVER LINE A/B), if the signal-to-noise ratio on the line exceeds the 
threshold value. 
 
To set the SNR margin threshold: 
1.  From the SHDSL Port Configuration menu, select SNR margin threshold. 
2.  Enter the desired value (0 dB to 15 dB). 
3. Select Save to save the changes. 
Configuring the SHDSL Repeater 
Configuration parameters of the SHDSL repeaters are similar to those of the SHDSL 
device, except for the following: 
•  Selecting repeater that you intend to configure 
•  Selecting power backoff for the customer and network sides of the repeater.
