SECTION 14. PTCs shall provide as many points of presence as necessary to effect an efficient interconnection.

SECTION 15. The inter-exchange carrier shall provide interconnecting facilities up to the main distribution frame (MDF) of the local exchange carriers with 5000 exchange lines or less per local area.  For LECs with more than 5000 exchange lines Section 12 shall apply; provided that the pending application for local telephone service in a particular local area is less than 25% of the number of working direct exchange lines.  The international gateway operator shall provide the interconnecting trunks up to the MDF of the LEC when the IXCs cannot provide the required toll facilities.  In case an LEC also provides an IXC facility, all types of traffic shall be routed via the trunk level.

SECTION 16. Interconnection shall be for a reasonable time frame and for sufficient capacity and in sufficient number to enable messages conveyed to conveniently meet all reasonable traffic demands for conveyance of messages between the system of the parties involved in the interconnection.

SECTION 17. Pursuant to Section 4 of Executive Order 59 local exchange provider or carrier (LEC’s) shall agree with the inter-exchange carrier and/or the IGF operator interconnecting with the former to provide an exclusive fixed carrier access code with prior coordination and subject to the approval of the Commission, in order that any subscriber of the LEC may access the long distance carrier of choice.

Ultimately, as the Local Exchange Carrier (LEC) upgrades to stored-program-control (SPC) exchanges they may implement equal access preprogrammed option and still allow the subscriber at the time of his call freedom of selection of any other inter-exchange or international gateway carrier.

Article IV
Operation of an International Gateway

SECTION 18.    Interconnection among public communication carriers shall be effected in such a manner that permits rerouting of calls from an international gateway operator which is rendered inoperative whether in whole or in part in the event of strikes, lockouts disasters, calamities and similar causes to other international gateway operators.

SECTION 20.    The technical/operating rules shall whenever applicable, be in accordance with duly approved and adopted International Telecommunications Recommendations.

Article V
Charges and Settlements

SECTION 21.    Settlement shall be effected through bilateral negotiations between interconnecting parties and shall conform with the following:

21.1  The reasonable cost of interconnection shall be shared by the interconnect parties in accordance with the traffic requirements and the terms and conditions of the Interconnect Agreement or Interconnect Mandate, as the case may be; provided, however that when one of the interconnecting parties is a local exchange carrier with 5000 exchange lines or less in which case Article III Section 15 shall apply.

21.2  For networks interconnected at the local exchange level, the LEC shall charge a network access charged based on the volume of traffic either on a per minute or volume of information with appropriate day and night differentiation.

In case of store and forward facsimile, data and voice mail, paging, trunked radio and other services interconnected to the local exchange network, and where the services derived from such interconnection would generate local traffic, the settlement shall be on the basis of the equivalent monthly trunk lines charges as generally charged by the LEC to the customer owning their own PABXs.  However, where toll traffic are derived from such services, Section 21.3 shall apply for statement purposes.

21.3  For networks interconnected at the trunk exchange level, the network access charge shall be determined as follows:

Each LEC shall develop a standardized procedure, hereafter known as a “Cost Manual,” for calculating the costs of the facilities used in the provision of toll carrier interconnection service.

1.      The starting point for calculation of LEC costs shall be the total company books that conform to generally accepted accounting principles.

2.      Individual companies with more detailed accounting structures can use that information to develop their costs of service, provided that the account detail conforms to generally accepted accounting principles.

3.      Investments or expenses that can be identified as directly attributable to toll carrier interconnection service can be directly assigned to that service category.

4.      An investment or expense which is utilized in the production of toll carrier interconnection service and one or more other services (e.g., basic local exchange service) shall be allocated using a methodology which most appropriately reflects the cost-causative characteristics of the services.  To the extent feasible, LECs should use existing records/reports to allocate the investment or expense into the appropriate service categories.  If existing carrier records do not provide sufficient detail, it may become necessary to perform a “special study” (recognizing cost-causality) to allocate investments and expenses among the appropriate service categories.  If a carrier can demonstrate that allocation on the basis of cost-causation is impracticable or unreasonable for certain investments or expenses, it may allocate those costs using an explicit allocation formula subject to approval by the Commission.

5.      A portion of common “overhead” costs of the LEC, such as general administrative costs, shall be allocated to the toll carrier interconnection service category based on a specific allocation formula that will be subject to review by the Commission.

Within one hundred and eighty (180) days of the effective date of this Circular, each LEC shall furnish the Commission with a copy of its Cost Manual and a full reporting of the costs determined in accordance with the Cost Manual, for review and final approval by the Commission.

SECTION 22.    In the course of the bilateral negotiations process, each LEC shall develop network and end user access charges for toll carrier interconnection, based on the costs of providing toll interconnection service as defined by the LEC’s approved Cost Manual and associated cost study results, in the following manner:

22.1  Network access charges applicable to the toll provider on a per minute basis, that recognize the volume of traffic carried, the distance covered, and an appropriate differential between the day and night rate periods.  The access charge rates for inbound vs. outbound calls may be deaveraged as negotiated by the parties, subject to the approval of the Commission.

22.2  An operator surcharge for operator-assisted toll calls shall be collected and kept by the service provider employing the operator.

22.3  An end user access charge shall be collected monthly and kept by the LEC, which recovers a portion of the non-traffic-sensitive costs of the local exchange switching facilities used jointly in the provision of basic local service and toll carrier interconnection service.  The end user access charge shall in no case exceed ten percent (10%) of the end user’s recurring monthly charge for basic local exchange service subject to the approval of the Commission.

22.4  For each LEC, the total annual revenue generated by the network access charges, operator surcharge, and end user access charge under reasonable estimates or forecasts of associated demand shall be equal to the total costs determined for the toll carrier interconnection service category in accordance wit the LEC’s Cost Manual.

22.5  All access charges, whether end user, operator surcharge, network access charges, shall be subject to approval of the Commission.

SECTION 23.    Access charge scheme of revenue settlement shall be fully implemented not later than two (2) years from the effectivity of this Circular.

SECTION 24.    The interconnecting parties shall submit to each other monthly settlement reports and other reports needed for the settlement within ninety (90) days following the end of each month.  The party with balance after reconciling their settlement reports shall pay the other party said balance not later than thirty (30) days after the reports have been received by both parties.  Amounts due which are not paid within the said period shall bear interest at mutually agreed rate.

Article VI
Transitory Provision

SECTION 25.    Interconnecting parties may agree that existing PTCs who do not presently comply with the prescribed standards, may enter or maintain their existing Agreement whereby they shall use technical standards other than those specified in NTC MC No. 10-16-90 for a period not exceeding three (3) years from the effectivity of this circular.

SECTION 26.    Existing settlement agreement shall remain in force for a period not exceeding two (2) years from the approval of this circular.

SECTION 27.    Interim settlement agreements using the revenue sharing scheme pursuant to NTC Case No. 88-145 may be entered into by the interconnecting parties for a period not exceeding two (2) years from the approval of this circular.

Article VII
Penalties for Violations

SECTION 28.    Any violation of the order promulgated by the Commission pursuant to Executive Order 59 and its Implementing Guidelines shall, upon due notice and hearing, be subject to any combinations of the following penalties.

28.1  Imposition of such administrative fines, penalties and sanctions as may be allowed or prescribed by existing laws.

28.2  Suspension of further action on all pending and future applications for permits, licenses or authorizations of the violating carrier or operator.

28.3  Disqualification of the responsible employees, officers or directors of the violating carrier or operator from being employed in any enterprise or entity under the supervision of the Commission.

28.4  Suspension of the authorized rates for any service or services of the violating carrier or operator without disruption of its services to the public.

Article VIII
Final Provisions

SECTION 29.    Any portion or section of this circular which may be declared to be invalid or unconstitutional shall not affect the validity of the other remaining portions or sections.

SECTION 30.    All existing memoranda, circulars, rules and regulations inconsistent with the provisions of this circular are hereby repealed or amended accordingly.

SECTION 31.    This circular shall take effect fifteen (15) days after its publication in the Official Gazette or newspaper of general circulation, provided further that at least three (3) certified copies thereof shall be filed with the University of the Philippines Law Center.
