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. 517 $aANSI/IEEE Std 1051-1988: IEEE Recommended Practice for Parameters to Characterize Digital Loop Performance 606 $aDigital electronics 606 $aElectric apparatus and appliances$xTesting 615 0$aDigital electronics. 615 0$aElectric apparatus and appliances$xTesting. 676 $a621.37 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910135446003321 996 $aANSI$92072434 997 $aUNINA
