Traffic Type Attributes
1. Select the Traffic Type tab from the Add Offnet Circuit dialog box to specify 
traffic descriptor (TD) settings for forward and reverse traffic. Figure 18-5 shows 
the Traffic Type tab.
Figure 18-5. Add OffNet Circuit: Traffic Type Tab
On an FRF.5 circuit, the Reverse QoS class is not configurable by the user, but is set 
by the NMS based on the service type of the destination endpoint and the QoS class of 
the originating endpoint. However, the TDs for the destination endpoint can be 
configured by the user. If both endpoints are Frame Relay service, then the QoS class 
of the originating endpoint is used for the terminating endpoint.
Note  – If the Non Call Initiator For FRF.5 FR-SPVC check box is not selected on the 
Offnet EndPoint Selection dialog box, the Traffic Type tab is unavailable and these 
attributes do not need to be set.
