There is an unique VPI and VCI value for Internet connection supported by ISP. The range of VIP
is from 0 to 255 and VCI from 0 to 65535.
VPI (Virtual Path Identifier) : for set up ATM Permanent Virtual Channels(PVC).
VCI (Virtual Channel Identifier) : for set up ATM Permanent Virtual Channels(PVC).

You can setup virtual circuit quality of service, VC QoS, using qos command. The router supports
UBR, CBR, VBR-rt and VBR-nrt. Move the cursor to qos and press enter.

UBR (Unspecified Bit Rate) is the simplest service provided by ATM networks. There is no
guarantee of anything. It is a primary service used for transferring Internet traffic over the ATM
network.
CBR (Constant Bit Rate) is used by connections that requires a static amount of bandwidth that is
avilable during the connection life time. This bandwidth is characterized by Peak Cell Rate (PCR).
Based on the PCR of the CBR traffic, specific cell slots are assigned for the VC in the schedule
table. The ATM always sends a signle cell during the CBR connection’s assigned cell slot.
VBR-rt (Varible Bit Rate real-time) is intended for real-time applications, such as compressed
