window. The Traffic Contract Type needs to be selected dependent upon the type of
connection selected in the previous windows. For ATM-VP connections, classes selectable
are CBR (Constant Bit Rate), UBR (Unspecified Bit Rate), UBR.1, RT-VBR 1, 2, or3 (Real
Time Variable Bit Rate). Or NRT-VBR 1, 2, or 3 (Non-Real Time Variable Bit Rate). For
ATM-VC connections, NRT-VBR 1, 2, or 3 , or UBR , UBR.1, or CBR are selectable.
Note: The Cellworx STN system can support any ATM Forum UNI 3.1 based traffic
contracts. UNI 3.1 uses QoS Classes 0 through 4 to specify the service requirements and
these can be mapped to Cellworx STN Classes I, II, and Unspecified. The Cellworx STN
also supports ATMF UNI 4.0 based traffic contracts. UNI 4.0 uses parameterized QoS,
which can be mapped to STN classes I, II, or Unspecified based on the QoS parameter
values. There are five traffic contract types (i.e. conformance definitions) for different
service categories.

Next select the Ingress Traffic Contract using the left mouse button. If a traffic contract
is not available for the connection, double click on NEW to create a traffic contract and go
to DLP-709. The traffic contract specifies the parameters that determine if the connection is
actually a CBR, RT or NRT-VBR.1, VBR.2, or VBR.3, UBR, or UBR.1 connection.
14. Once traffic contract is created, it will appear in the Ingress Traffic Contract window.
Select the new traffic contract via a single click using the left mouse button.
