IEEE Recommended Practice for Parameters to Characterize Digital Loop Performance
New IEEE Standard - Inactive-Withdrawn.
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.
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.
