The New Network Service Provider (NNSP) is responsible for resolving Customer Trouble Reports (CTRs) from their own end-user customers. Misdirected repair calls to CenturyLink instead of the NNSP will be redirected to the NNSP.
CenturyLink will work cooperatively with the NNSP to resolve CTRs when the trouble condition has been isolated and determined to be within the CenturyLink Network.
If the service provider's end-user customer calls the CenturyLink Repair Center for Customer Service because the customer has experienced trouble on their line, the customer will be referred to the service provider serving its account.
