This is a new C7 deployment (new to me and to the organization).  I migrated all my existing DSL customers onto the C7 (using the ADSL2+ cards).  I used the subscriber provisioning Add Subscriber wizard and provisioned them using the default UBR traffic profile.
I did not know, at that time, that the UBR traffic profile was limited to approximately 2.XMbits.  I've since discovered that I can create my own traffic profiles and have created two (8Mbit max, and 20Mbit max) for testing purposes.
How can I change an existing subscriber's traffic profile?
When I try to use the Add Subscriber wizard, my custom traffic profiles do not show up in the list of traffic profiles from which I can choose.  I am currently not comfortable deleting the customer's cross connect and recreating it by hand.
