Characteristics of Special Quality International Leased Circuits with Basic Bandwidth Conditioning - Maintenance: International Leased Circuits (Study Group IV) 11 pp
This Recommendation deals with leased circuits for uses other than telephony, for example.datatransmission. The requirements of this Recommendation are intended to ensure the provision of a circuit which will meet the requirements of digital transmission rates higher than those possible on a normal telephone-type circuit2). In particular, circuits meeting the requirements of this Recommendation are intended for use with modems which contain equalizers. Circuits conforming to this Recommendation may not always support satisfactory operation of modems to Recommendation V.29. This is dependent upon the equalization capability of the particular modems used.
