Field Description
VPI Virtual Path Identifier. This is a read-only field and is selected on the Select
column in the Current ATM VC Table.
VCI Virtual Channel Identifier. This is a read-only field and is selected on the
Select column in the Current ATM VC Table. The VCI, together with VPI, is

QoS Quality of Server, a characteristic of data transmission that measures how
accurately and how quickly a message or data is transferred from a source
host to a destination host over a network. The four QoS options are:
− UBR (Unspecified Bit Rate): When UBR is selected, the SCR
and MBS fields are disabled.
− CBR (Constant Bit Rate): When CBR is selected, the SCR
and MBS fields are disabled.
− nrt-VBR (non-real-time Variable Bit Rate): When nrt-VBR is
selected, the SCR and MBS fields are enabled.
− rt-VBR (real-time Variable Bit Rate): When rt-VBR is
selected, the SCR and MBS fields are enabled.
PCR Peak Cell Rate, measured in cells/sec., is the cell rate which the source may
never exceed.
SCR Sustained Cell Rate, measured in cells/sec., is the average cell rate over the
duration of the connection.
MBS Maximum Burst Size, a traffic parameter that specifies the maximum
number of cells that can be transmitted at the peak cell rate.
