This recommended practice suggests a set of performance parameters for digital loop transmission between the user location and the serving office. In the case of ISDN the user location is defined as the T-reference point, or the U-reference point. In the case of non-ISDN, the user location is defined as the point in the transmission circuit analogous to the ISDN-defined T or U reference point. This recommended practice is limited to user information bit rates of 200 kb/s or lower.ANSI/IEEE Std 1051-1988: IEEE Recommended Practice for Parameters to Characterize Digital Loop PerformanceDigital electronicsElectric apparatus and appliancesTestingDigital electronics.Electric apparatus and appliancesTesting.621.37NjHacINjHaclDOCUMENT996279862403316ANSI2072434UNISA01114nam 2200361 450 991082138730332120201206095004.01-5231-4597-81-63081-770-8(CKB)4100000011478589(MiAaPQ)EBC6371469(EXLCZ)99410000001147858920201206d2020 uy 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierLithium-ion batteries and applicationsA practical and comprehensive guide to lithium-ion batteries and arrays, from toys to townsVolume 2 /Davide AndreaBoston ;London :Artech House,2020.1 online resource (479 pages)1-63081-769-4 Lithium ion batteriesLithium ion batteries.621.312424Andrea Davide763139MiAaPQMiAaPQMiAaPQBOOK9910821387303321Lithium-ion batteries and applications4030745UNINA
