Version : Revised
Date of adoption : 1992
Notes :
Recommendation D.4 details the provisions applicable to leased
international (continental and intercontinental) sound- and
television-programme circuits and associated control circuits for
private service. The provisions of Recommendation D.4 should be
applied in conjunction with Recommendation D.1, except where
specifically stated otherwise.
Sound- and television-programme circuits provided on an occasional
basis are subject to the provisions of Recommendation D.180.
Provisions governing the technical aspects and maintenance of
sound- and television-programme circuits are contained in the
J-, M-, and N- Series Recommendations.
The general principles as stated in º 1 of Recommendations D.1 and
D.180, where applicable for leased international sound- and
television-programme circuits, shall serve for Recommendation D.4.
The Administrations concerned may agree upon additional principles, if
desired.
Recommendation D.4 is intended to cover the use of circuits for
sound- and television-programme transmission purposes only, unless
otherwise agreed upon by the Administrations providing the circuits.
Recommendation D.4 includes an example of an international
sound-programme connection and of an international television-programme
connection involving a satellite circuit, precises the principles
applicable to duration of the lease charging and cancellation,
particularly in case of allowance for interruption. It also states
the special conditions applicable to leased sound- and/or
television-programme circuits (two-way circuits, interconnection,
offered bandwidths, use of the vertical blanking interval).
