Information technology. Telecommunications and information exchange between systems. DTE/DCE interface back-up control operation using ITU-T Recommendation V.24 interchange circuits Ingestion-build-95349 concentricity and runout are explained1 Scope This International Standard specifies the procedures for back up operation applicable to data transmission on a leased line when implemented through a single interface, controlling both the leased and the back up facilities, using ITU T Recommendation V. 24 interchange circuits in conjunction with either the 25 pole connector (ISO 2110) or the 26 pole connector (ISO IEC 11569). The method used to switch the transmission of data automatically
