Chapter 22: Configuring ATM Virtual Circuits
Avidia System Configuration and Management User Manual 429
Adding ATM Traffic Profiles
ATM traffic profiles are stored in the ATM Traffic Descriptor Configuration Table window. Each
profile has an index number assigned to it. You use the index number to assign a profile to an
ATM connection.
1 In the
Traffic Type box, select the desired traffic descriptor type (UBR, CBR, rt-VBR or nrt-VBR).
The text boxes to the right display the default parameter values for the selected traffic type.
2 Type the desired information in the text boxes as follows:
3 To activate the profile, click Add. The new profile is assigned an index number and is
displayed in the
ATM Traffic Descriptor Table.
