The document to which this cover statement is attached is submitted to a Formulating Group or
sub-element thereof of the Telecommunications Industry Association (TIA) in accordance with the
provisions of Sections 6.4.1–6.4.6 inclusive of the TIA Engineering Manual dated October 2009, all
of which provisions are hereby incorporated by reference.
Abstract
This contribution proposes adding a new sub-clause to TIA-968-B, sub-clause 5.1.9 conditions for
requirements for testing wideband and narrowband analog telephones for out-of-band tests in sub-clauses
5.1.7 and 5.1.8.
There is no clause in the out-of-band section of TIA-968-B that mentions TE with an acoustic input (i.e.
handsets) to have a stimulus applied to them for the out-of-band signal level tests.

Add the following to the NORMATIVE REFERENCES in TIA-968-B:
6. IEEE Std 269-2010, IEEE Standard Methods for Measuring Transmission Performance of
Analog and Digital Telephone Sets, Handsets, and Headsets
Add the following new sub-clause to TIA-968-B 5.1.9 “Conditions for requirements in sub-clauses 5.1.7
and 5.1.8”:
5.1.9.4 Voice terminal equipment containing electroacoustic transducers for live voice input,
including recording devices, shall comply with the limitations with a real male speech
as specified in IEEE Std 269 set to a level of -4.7 dBPa acoustic signal applied to the
electroacoustic transducers.
