Configuring the SHDSL Interface
The ASMi-52 configuration software allows you to change the modem’s
transmission mode (Annex A or Annex B).
Examples given below illustrate the local device configuration procedures.
To change the transmission mode:
1. From the SHDSL Local Port menu, select Transmission Mode (Main menu >
Configuration > SHDSL Configuration > SHDSL Local Port > Transmission
Mode) to choose a transmission mode: Annex A or Annex B for the SHDSL
Local Port.
The display is refreshed and a new value appears.
2. Select Save to save the changes.
• ASMi-52 units operating in the receive clock mode automatically detect the
standard compatibility value of the central units and configure themselves
accordingly.
