Description / Abstract:

This standard specifies Radio Frequency (RF) immunity performance criteria for two-wire Telephone Terminal Equipment (TTE) having an acoustic output and two-wire TTE adjunct devices with connection port for Telephone Terminal Equipment (TTE) having an acoustic output. Acoustic output requirements are only defined for TTE having a handset normally held to the ear of the user, but guidance on extending the requirements to TTE having other types of acoustic outputs, such as speakerphones, answering systems and telephones with headsets, is provided in an informative annex.

Criteria are specified for immunity to radiated RF signals over the frequency range from 150 KHz to 150 MHz and for immunity to longitudinal (common mode) conducted RF signals over the frequency range from 150 KHz to 30 MHz. Criteria for immunity to metallic (differential) conducted RF signals on signal leads are not covered.

In addition to the performance levels themselves, this standard includes recommended test procedures or references to existing standards wherein such procedures will be found.

This standard does not consider immunity performance criteria to intentional network signals (e.g. xDSL).
