Set up the modem in Bridged/RFC1483 mode
For the Bridged/RFC1483 mode there are a minimum of settings that have to be set.
VP and VC identifiers
Asynchronous Transfer Mode (ATM) is the technology used for data transmission. The
data is transmitted over virtual channels that are designated by specific unique identifiers
(virtual channel identifiers or VCIs). There can be multiple VCIs in one virtual path and
the virtual path also has a unique virtual path identifier (VPI).
The parameters for VP and VC should be one pair identifying DSLAM (equipment at the
ISP side of the ADSL line) and ISP router. This pair should be provided by the access
network operator.
Encapsulation type
When data is transferred via ATM Virtual Channels it is encapsulated using a specific
method. By default, the Bridged/RFC1483 mode uses LLC (Logical Link Control)
encapsulation, which allows multiplexing of multiple protocols over a single ATM virtual
circuit. The second available method is VC Mux (VC Multiplexing), which uses a
separate VC for each carried protocol. Refer to your ISP/service provider documentation.
