Flexible NXX Code Rating. It shall be Carrier’s responsibility to designate a rating point and routing point for each assigned NXX code, which may be different from one another. For tandem interconnected calls, Carrier shall select a Rate Center for each NXX code assigned to it at either its NPOI or an Ameritech End Office located in the same LATA as the Carrier’s NPOI. Ameritech shall, within sixty (60) days of a completed request by Carrier in the proper format, implement in its switches the rate center locations initially designated by Carrier, provided however, that Carrier shall not request more than seven (7) NXX code implementations in any one (1) week. In addition, Carrier shall provide adequate termination facilities on Carrier’s switches to accommodate the traffic terminated to it. The sixty (60) day interval shall not apply to subsequent changes in the rate center location.
