Description
Virtual Path Identifier (VPI) and Virtual Circuit
Identifier (VCI).
Data flows are broken up into fixed length cells,
each of which contains a Virtual Path Identifier
(VPI) that identifies the path between two nodes,
and a Virtual Circuit Identifier (VCI) that identifies
the data channel within that virtual path. Each
virtual circuit maintains a constant flow of cells
between the two end points. When there is no data
to transmit, empty cells are sent. When data needs
to be transmitted, it is immediately inserted into the
cell flows.
Specifies how to handle multiple protocols at the
ATM transport layer.

Enter the maximum idle time for the Internet
connection. After this time has been exceeded the
connection will be terminated.
Choose the ISP to whom this connection will apply.
VC-MUX: Point-to-Point Protocol over
ATM Virtual Circuit Multiplexer (null
encapsulation) allows only one protocol
running per virtual circuit with less overhead.
LLC: Point-to-Point Protocol over ATM
Logical Link Control allows multiple
protocols running over one virtual circuit
(uses slightly more overhead).
