VCI (Virtual Channel Identifier): This is the label given to an ATM VC to identify it and determine its destination. The VCI is a 16-bit number that is included in the header of an ATM cell.

VPI (Virtual Path Identifier): A virtual path determines the way an ATM cell should be routed. The VPI is an 8-bit (in UNI) or 12-bit (in NNI) number that is included in the header of an ATM cell.
The values for VPI and VCI are 0 and 35 respectively.
