Setting Description
DSL Transfer Mode Select one of the following DSL transfer methods:
• PTM. Packet Transfer Mode (PTM) has a functionality that is similar to
packet-switched networking and does not use multiplexing.
• ATM. Asynchronous Transfer Mode (ATM) uses Asynchronous Time-Division
Multiplexing (ATDM) to encode data into small, fixed-sized cells. ATM has a
functionality that is similar to circuit-switched networking and small-packet-switched
networking.
When you select ATM, you also need to configure the multiplexing method, VPI,
and VCI.
Multiplexing Method Select the VDSL multiplexing method for the ATM mode:
• LLC-BASED. Multiplexing is based on Logical Link
Control (LLC) encapsulation.
• VC-BASED. Multiplexing is based on use of a virtual
circuit (VC).
VPI The Virtual Path Identifier (VPI) that is used for the VDSL
connection.
VCI The Virtual Channel Identifier (VCI) that is used for the
VDSL connection.
