Each Party agrees to provide the necessary Traffic data in conjunction with any such audit in a timely manner. 4.2 Nothing in this Agreement shall be construed to limit either Party’s ability to designate the areas within which that Party’s Customers may make calls which that Party rates as “local” in its Customer Tariffs. 4.3 MCIm and NPTC will each provide the other with an auditable Percent Local Usage (“PLU”) factors to be applied to their own originating traffic by the terminating Party. The Parties will provide an initial PLU prior to the first exchange of traffic, and then on a quarterly basis thereafter. After the initial PLU, the Parties agree that the originating quarterly PLU factor, which they develop, will be based on the previous three months’ originating traffic delivered to the other Party, and applicable to the following three months. The PLU provided by the originating Party will be utilized by the terminating Party to allocate traffic to the proper jurisdictional uses, as set forth below. If either Party does not provide an updated PLU, the previous PLU will be utilized until such time as a new PLU is furnished, subject to the audit procedures set forth in this Agreement. PLU changes will be utilized on a going-forward basis. 4.4 If the originating Party also chooses to combine Interstate and Intrastate Toll Traffic on the Interconnection Trunk group, such Party will supply an auditable Percent Interstate Use (PIU) factor quarterly, based its previous three months’ originating traffic, and applicable to the following three months. If either Party does not provide an updated PIU factor, the previous PIU factor will be utilized until such time as a new PIU is furnished, subject to the audit procedures set forth in this Agreement. PLU changes will be utilized on a going-forward basis. 4.5 To the extent technically feasible, each Party shall pass Calling Party Number (CPN) information on at least ninety-five percent (95%) of calls carried over each call.

The Parties agree that they will not populate the CPN field in the call detail record with a wholesale Customer's billing or local routing number but will utilize the final end user Customer's CPN or billing number. 6.1.1 As 4.6 Where possible, actual call detail records including the CPN, will be used in this Section 6, “Traffic Rate” means by the terminating Party to determine the applicable jurisdiction of terminating traffic for billing and compensation. Where a terminating Party has the capability, it will use the actual call detail records including the CPN information associated with each specific call to identify, on an automated basis, traffic delivered by the originating Party as either Reciprocal Compensation Traffic rate, Measured Internet or Toll Traffic rate, intrastate Switched Exchange Access Service rate, interstate Switched Exchange Access Service rate, or intrastate/interstate Tandem Transit Traffic rate, as provided in the Pricing Attachment, an applicable Tariff, or, for Measured Internet Traffic, the FCC Internet Order. 6.1.2 If the originating Party passes CPN on ninety-five percent (95%) or more of its calls, the receiving Party and shall xxxx the originating Party the Traffic Rate applicable to jurisdictional rates for each relevant minute of traffic for based on the jurisdiction of the call as determined from the actual call detail records including the CPN. Where a terminating Party does not have the capability to identify the applicable jurisdiction of a call by utilizing the CPN information associated with that call, the terminating Party will utilize the PLU factor to allocate by jurisdiction that traffic which it cannot determine the jurisdiction using the CPN. 4.7 When a terminating Party receives insufficient call detail associated with a call or the CPN is passed. For any remaining (up to 5%missing or masked, and therefore cannot determine the jurisdiction of a call, the terminating Party will allocate such traffic that it cannot identify by jurisdiction utilizing the following procedures: 1.) If the percentage of traffic delivered with CPN is greater than 90% the calls delivered without CPN information, the receiving Party shall xxxx the originating Party for such traffic at the Traffic Rate applicable to each relevant minute of traffic, in direct proportion to the minutes of use of calls passed with CPN information. 6.1.3 If the originating Party passes CPN on less than ninety-five percent (95%) of its calls will be allocated and the originating Party chooses to combine billed as Reciprocal Compensation Traffic and or Toll Traffic using the PLU factor. If a Party's originated traffic has CPN on fewer than 90% of the same trunk groupcalls, the receiving other Party may provide written notice of a billing dispute to the Originating Party. Upon such notice, the Party originating the traffic (the "Originating Party) shall have 30 days to investigate and correct the lack of CPN and report the date the problem was corrected to the other Party (the Terminating Party). If the problem cannot be repaired within 30 days of the written notice to bring the originated traffic without CPN to fewer than 10% of total traffic, the Terminating Party will xxxx the higher of its interstate Switched Exchange Access Service rates or its intrastate Switched Exchange Access Services rates for all traffic that without CPN as Access traffic juridictionalized using the PIU until such time as the traffic without CPN is passed without CPN, unless the Parties agree that other rates should apply to such fewer than 10% of total traffic. 6.2 At such time 4.8 Where the Interconnection Trunk group is provisioned as a receiving two-way trunk group and each Party has delivers its originating traffic over that same trunk group to the capabilityother Party, each Party shall pay its proportionate share of the recurring charges for the transport facilities that are located within the NPTC service area between the IP and the NPTC boundary with Verizon Pennsylvania Inc. The prorated share of facility costs between the Parties for the use of the two-way Interconnection Trunk facilities will be based on an automated basisthe percentage of the total traffic originated by each Party, excluding Transit Traffic and ISP-Bound Traffic. The initial proportionate share factors, for the Interconnection Trunk facilities, will be 50% assigned to use such CPN MCIm and 50% assigned to classify NPTC. These initial proportionate share factors will be updated three (3) months after the Effective Date of this Agreement, based upon the actual percentage of traffic delivered as set forth above in this Section. Beginning six months after the initial factors are determined, and at either Party’s request, but no more than twice a year, the Parties shall determine the applicable proportionate share factors based upon the previous six (6) months’ originating traffic sent by each Party over the Interconnection Trunks Trunk group as set forth above in this Section. When updating the proportionate share factors, the Parties will share the data and results of their measured traffic usage which forms the basis of their proposed proportionate share calculation and will work cooperatively on a mutually agreeable percentage. 4.9 The proportionate share factors will be utilized by NPTC in developing the invoice for the Interconnection facilities, which MCIm will order from NPTC for the Interconnection Trunk group. NPTC will xxxx MCIm the applicable Interconnection (flat rated) transport charges for the Interconnection Trunk group. The Interconnection charges billed by NPTC to MCIm, for the DS1 and/or DS3 Interconnection services that are ordered by MCIm for the Interconnection Trunk group, will be reduced by the other Party NPTC proportionate share of the facility as calculated and set forth above. 4.10 MCIm agrees that it is responsible for all the Interconnection facility charges due NPTC for the Transit Trunk group facilities within the NPTC service area and that no prorate of those Interconnection facility charges will be applied by Traffic Rate type (e.g., Reciprocal Compensation Traffic/Measured Internet Traffic, intrastate Switched Exchange Access Service, interstate Switched Exchange Access Service, or intrastate/interstate Tandem Transit Traffic), such receiving Party shall xxxx NPTC to that portion of the originating Party the Traffic Rate applicable NPTC invoice to each relevant minute of traffic for which CPN is passed. If the receiving Party lacks the capability, on an automated basis, to use CPN information on an automated basis to classify traffic delivered by the other Party by Traffic Rate type, the originating Party will supply Traffic Factor 1 and Traffic FactorMCIm.
