IEEE Standard Test Procedure for Measuring Longitudinal Balance of Telephone Equipment Operating in the Voice Band
| Published By | Publication Date | Number of Pages |
| IEEE | 1985 | 25 |
Revision Standard – Inactive-Withdrawn. 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.
