The Guidelines require the exiting CLEC (and, when applicable, any arranged carriers) to jointly notify customers 60 days in advance of the final service termination date. The notification letter must comply with Federal Communications Commission (FCC) and Commission requirements including a listing of the service rates and terms of any arranged carrier named in the notice. Applicant and AT&T California jointly mailed a written notice to all of its affected customers on a rolling basis beginning April 2, 2007, and have met our requirement to notify customers 60 days in advance.
