Scope
Scope and Limitations. 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 (1) the T-reference point@ or (2) 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 ISDNdefined T or U reference point. This recommended practice is limited to user information bit rates of 200 kb / s or lower. Purpose. The purpose of this recommended practice is to suggest a set of transmission performance parameters to be used in the development of standards for low bit-rate digital channels between the user's location and an appropriate test point at the serving office.
