The basic requirements for a test circuit that can be used to measure longitudinal balance are defined. Resistive elements are specified because they are generally considered easy to duplicate and balance. Standard test conditions and procedures are established.

455-1976 - IEEE Standard Test Procedure for Measuring Longitudinal Balance of Telephone Equipment Operating in the Voice Band
September 30, 1976 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Telephone companies and equipment manufacturers have generally agreed on a definition for longitudinal balance for many years. This agreement extends also to the basic approach followed when measuring balance. Testing a device for balance involves the application of a longitudinal voltage. Then any ...
