5.4.2. Configure SHDSL parameters
This section shows how to setup the SHDSL parameters: SHDSL Mode, Annex type, Psd Mask, SNR margin.
Select Shdsl, and press [ENTER] or [RIGHT].
Setup SHDSL Parameter, Mode
Press [TAB] to select the operating type and press enter to finish setting.
The SHDSL modes have three types: STU-R, STU-C-INTCLK and STU-C-EXTCLK
INTCLK: The device will generate the appropriate clock speed defined by the speed setting of the interface.
EXTCLK: The device will accept the clock from the interface and will use that clock to receive and transmit data across the
interface.
Most point-to-point applications use Internal Clock. If the DTE provides a clock with TX data, the clock can be set to External
Clock.
For Ethernet interface model, since Ethernet does not provide a clock, the correct setting for CO side NTU should always be
STU-C-INTCLK.
