VPI/VCI
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.
Encapsulation
Specifies how to handle multiple protocols at the
ATM transport layer.
•
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.)
Idle Time (Minute)
Enter the maximum idle time for the Internet
connection. After this time has been exceeded the
connection will be terminated.
ISP Name
Choose the ISP to whom this connection will
apply.
