In meeting its own telecommunications requirements in AS, the US shall lease commercial circuits and pay the costs of such leases using the procedures outlined in Annex D. SIMPSON System 2. Responsibilities for operation of trunk lease charges are contained in Appendix 1 to Annex A; specifically: (a) Payment for trans-Pacific 9600 baud trunk - US (b) Payment for Paumalu/NAVCAMS EASTPAC circuit - US. (c) Payment for trans-Tasman 4800 baud trunk - AS (d) Payment for local circuit in AS - AS. Costs of trunk lease charges are apportioned in accordance with allocation of system capacity, as stated in paragraph 4. 3. Unless otherwise stated in this Agreement, spare system capacity either existing at the time this understanding becomes effective or created as a result of subsequent system expansion, equitably shall be made available on a reimbursable basis to either party as valid requirements are identified. Appendix 1 to Annex A reflects the existing spare capacity. This Appendix shall be updated on a regular basis to reflect configuration changes. 4. Each party's share of the cost of the system shall be determined by the percentage of capacity used by that party at the CODEX 980 level of multiplexing, relative to the total capacity in use at that level. Allocation of circuit capacity is outlined in Appendix 1 to Annex A. 5. In those instances where ASDOD leases equipment from the USDOD, AS shall reimburse the lease payments to the US as designated in its lease arrangement.
