ASMi-52 Ver. 2.8 Configuring for Operation 4-21
Setting the SNR Margin Threshold
The signal-to-noise ratio threshold can be set. ASMi-52 generates minor alarm
(SNR MARGIN OVER LINE A/B) if the signal-to-noise ratio on the line exceeds the
threshold value.
³ To set the SNR margin threshold:
1. From the SHDSL Local Port/SHDSL Remote Port/SHDSL Repeater menu, select
SNR margin threshold (Main menu > Configuration > SHDSL Configuration >
SHDSL Local Port/SHDSL Remote Port/SHDSL Repeater > SNR Margin
Threshold).
The SNR margin threshold can also be configured from the SHDSL remote or
local port, or from the SHDSL repeater.
2. Enter the required 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 when selecting a repeater that you intend to configure with
your own set of configuration.
The SHDSL repeaters are configured via the SHDSL Repeater menu.
³ To access the SHDSL Repeater menu:
• From the SHDSL Configuration menu, select SHDSL Repeater (Main menu >
Configuration > SHDSL Configuration > SHDSL Repeater).
The SHDSL Repeater menu is displayed (see
Figure 4-24 ).

Configuring the DTE Interface Data Rate
ASMi-52 supports multiple data rates between the range of 64 kbps and
4608 kbps, depending on the clock mode and line/DTE interface of the local and
remote units (see
Table 1-2 and Table 1-3 ).
