General The following arrangements are recommended for the drawing up@ exchange and acceptance of monthly telephone and telex accounts between Administrations. Each Administration of origin (and of transit where appropriate@ e.g.@ in the case of clause 3.1.4 below) shall prepare and forward monthly accounts. These should be drawn up separately on forms of the types shown below as specimens for: a) telephone traffic proper ?C Forms 1 or 2 (see Annex A); b) sound- and television-programme and phototelegraph transmissions ?C Forms 1 or 2 (see Annex A) suitably adapted; c) telex traffic ?C Forms 1 or 2 (see Annex B). The choice of form to be used for the accounts should be decided by the Administration which prepares the accounts@ after consultation with the other Administration concerned. It may be convenient to use separate forms for originated and transit traffic. The traffic details which must be included in the account are only those which are necessary for the purpose of international accounting. However@ by agreement between the Administrations concerned@ traffic information which is not essential for the accounts (e.g.@ the number of calls where this does not affect the accounting) may be included on the account forms. Monthly accounts should be sent as promptly as possible in time periods specified in the International Telecommunication Regulations and@ if mutually agreed@ Rec. ITU-T D.195.
