VPI and VCI values identify an ATM virtual connection. Because the modem
comes with preconfigured VPI/VCI values, you do not have to configure these
fields.
However, if the ISP or corporate network administrator requires VPI/VCI values
different from the default values, you must enter those values in these fields.

This field indicates the encapsulation of Ethernet or IEEE 802.3 frames to
AAL5/ATM protocol.
The ADSL modem supports both the LLC/NLPID method and the VC MUX
method for bridged Ethernet V2.0/IEEE 802.3 PDUs. By default, this field is set
to LLC/NLPID, and the access server of the ISP or corporate network must use
the same method. If it does not, contact the ISP or corporate network
administrator.
