TIA TSB-31-D PDF

This telecommunications systems bulletin (TSB) recommends test procedures, test equipment, and guidelines for determining compliance with the technical requirements of 47 C.F.R. Part 68 and the technical criteria adopted by the ACTA, most specifically TIA-968-B.

This TSB proposes at least one measurement procedure for each technical requirement and, in some cases, an alternative measurement procedure. Each test procedure in this document is referenced to the appropriate subclause of the applicable requirements document. These proposed procedures are not exclusive. Other measurement procedures and test equipment may provide equivalent results.

In the event of conflict between any of the standards outlined above and this TSB, the standard takes precedence.

These test procedures do not cover the administrative or other equipment authorization procedures that may be required to obtain product approval. Refer to the administrative requirements of the ACTA. TIA-TSB-129-B summarizes these administrative requirements.

Some of the tests or procedures specified in TSB-31-D may involve hazardous voltages and currents or other potential dangers. Some of these hazards have been identified, and appropriate warnings have been included in the text specifying such tests or procedures. Appropriate safety precautions are always recommended when performing any laboratory test or procedure.
