If a line is LLU, the equipment we have installed in the exchange needs to be configured with the details of the line. There are a number of settings for each line and, collectively, we refer to these as the 'traffic profile'.
During the provision of a new line, or a regrade, it may be necessary to set up or change these settings (the 'traffic profile').
Unfortunately, this can only be done manually via a configuration tool so, as part of the provisioning process, we check to see whether a traffic profile change may be required -- if one is not, fulfillment can continue without manual intervention, otherwise the fulfillment process takes a different route where the additional work for changing the traffic profile is performed manually by Service Provision.
Please note that although we use the term 'traffic profile', rest assured that this is not, and has absolutely nothing to do with, traffic shaping in any way, shape or form.
