Hence the name, "virtual path identifier." The 
VPI is used in conjunction with the VCI, or 
virtual channel identifier. 
VCI 
Stands for "Virtual Channel Identifier." The 
VCI indicates where an ATM cell is to travel 
over a network. The VCI within each ATM cell 
defines the fixed channel on which the packet 
of information should be sent. It is a 16-bit 
field, compared to the VPI, which is only 8 
bits. Since this numerical tag specifies the 
virtual channel that each packet belongs to, it 
prevents interference with other data being 
sent across the network. 
Bridging 
Here is related to the well-known RFC1483 
bridging protocol. This feature is working on 
the basic bridging protocol and physical layer. 
In this device, Modem serves as a bridge 
device, and does not provide any protocol 
transfer and address filtering features. In this 
case, the Modem actually plays the role as 
Hub.  
IPoA 
It is related to RFC1577. Usually the data
