Parameter
Description
VPI
VPI is 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 valid range for the VPI is 0 to 255. Enter the VPI
assigned by the ISP.
VCI
VCI 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. The valid range
for the VCI is 32 to 65535. Enter the VCI assigned by the
ISP.
QoS
UBR (Unspecified Bit Rate)
– Select UBR for
applications that are non-time sensitive, such as e-mail.
CBR (Constant Bit Rate)
– This class is used for
emulating circuit switching. The cell rate is constant with
time. Select CBR to specify fixed (always on) bandwidth
for voice or data traffic.
nrtVBR (non-real time Variable Bit Rate)
– This class
allows users to send traffic at a rate that varies with time
