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.621.37NjHacINjHaclDOCUMENT9910135446003321ANSI2072434UNINA00884nas 2200325- 450 991050292010332120230514213019.0(OCoLC)904427599(CKB)5300000000020131(CONSER)--2021220521(EXLCZ)99530000000002013120080619b18901891 --- aengur|||||||||||txtrdacontentcrdamediacrrdacarrierThe criticWashington, D.C. :Washington Critic Co.m1890-1891.1 online resource (1 volume)2157-2291 Washington (D.C.)NewspapersWashington (D.C.)fastNewspapers.fastPeriodicals.fast070JOURNAL9910502920103321The critic1890790UNINA
