CHANNEL CONFIGURATION

The Channel Configuration page configures channel operation modes of the

ADSL Router.

Figure 23: WAN Configuration

The following items are displayed on this page:

◆ Default Route Selection – Enables the default route to be specified or

selected automatically.

◆ VPI (Virtual Path Identifier) – A grouping of virtual channels which

connect the same end-points, and which share a traffic allocation.

◆ VCI (Virtual Channel Identifier) – A specific virtual channel connecting

two end-points.

◆ Encapsulation:

■

LLC (Logical Link Control) – This encapsulation method allows

multiplexing of multiple protocols over a single ATM virtual

connection. In some cases, the LLC header is followed by a SNAP

header which uniquely identifies a routed or bridged protocol. (This

is the default packet encapsulation format used for carrying IP

datagrams over AAL5 ATM.)
