INTERNATIONAL TELECOMMUNICATION UNION CCITT RECOMMENDATION SUMMARY Rec. No. : D.7 Title : Concept and implementation of "one-stop shopping" for international private leased telecommunication circuits Study Group : III - Tariff and Accounting Principles Version : New Date of adoption : 1992 Notes : Recommendation D.7 provides the general principles and procedures for the implementation of "one-stop shopping" (OSS) for international private leased telecommunication circuits (IPLC). OSS is an optional set of arrangements whereby an Administration (the coordinating Administration) handles coordination between a customer and other Administration(s) concerned [the participating Administration(s) in order to make it simpler for the customer leasing international private leased telecommunication circuits. Recognizing on one hand that each Administration's internal procedures and billing processes are different and on the other hand that OSS procedures should be harmonized as much as possible, Recommendation D.7 is only a guide to be used by Administrations cooperating in the provision of OSS. Details of procedures should be agreed among the Administrations concerned. The implementation of the OSS arrangement requires close coordination among the Administrations concerned at all levels, commercial and administrative, as well as technical. The Administrations concerned should endeavour to meet all the specific requirements of the customer including the choice of participating Administration(s). Recommendation D.7 encompasses the features of the OSS arrangement (single-point ordering, billing, fault reporting) the terms and conditions for the provision/cancellation of the lease, the way in which inter-Administration settlements are made, the procedure in case of allowance for service interruption.
