4.3 Configuring the Physical Ports
The SHDSL and DTE or LAN interfaces of the ASMi-52L modem are configured via
the Configuration menu. In addition, the SHDSL Configuration menu allows you to
configure the SHDSL repeaters (if they are installed in line).
The third line of the Configuration menu changes according to the DTE interface
installed in ASMi-52L. The possible options are:
• DTE Configuration for ASMi-52L units with a serial interface (V.35, X.21)
• LAN Configuration for ASMi-52L units with 10/100BaseT user interfaces.
Configuring the SHDSL Interface
The SHDSL interface is configured via the SHDSL Configuration menu, Figure 4-16.
