TR VoIP and PCM Terminal Transmission Performance: Chair: Allen Woo, Plantronics TR Chair s Report for February 2014 Working Group TR met on Monday, February 10, IEEE STIT joined the meeting in the afternoon session. The following people were in attendance: Attendee Company / Representing Bress, James AST Technology Labs Lawler, Tim Cisco Systems, Inc. Young, Bob Bob Young & Associates Nixon, Jason Industry Canada Woo, Allen Plantronics Bareham, John Consultant in Electroacoustics Whitesell, Stephen Whitesell Consulting LLC Hess, Glenn Harman International Industries Nixon, Jason Industry Canada Graham, Steve Plantronics Selling, Dan Plantronics The following people also participated in the meeting but apparently failed to sign in: Jasionowski, Tony, Al Baum. Project Status: The following is a summary of the status of each Project assigned to TR ANSI/TIA-PN B, Transmission Requirements for Digital Telephones with Handsets Current Status: The TIA B draft was reviewed by the editor, Steve Whitesell (Whitesell Consulting). Several issues were discussed including: 1. Which reference field to use for acoustic measurements: Ear Reference Point (ERP), Free- Field, Diffuse Field. Various industry standards specify these fields and it is not clear which is the best one to use for this standard. In addition, IEEE-STIT is working on defining another reference Natural Field which may be a better technical solution, bit it is not clear if this reference will be adopted globally. 2. How to specify conformance to the standard that includes narrowband and wideband requirements if a product does not include both transmission modes, or only passes the requirements for one mode. 3. Allow to use both L and G.722 codec for wideband testing. 4. The editor will make the changes to the draft recommended during the meeting. 3

9 c. TR Telephone Accessibility Performance Chair: James Bress, AST Technology Labs TR Chair s Report for November 2013 Working Group TR met on Wednesday, February 12, The following people were in attendance: Attendee Bress, James Lawler, Tim Nixon, Jason Rondon, Magdoly Jasionowski, Tony Kramarikova, Marianna Ivans, Randy Whitesell, Stephen Company / Representing AST Technology Labs Cisco Systems, Inc. Industry Canada Industry Canada Panasonic Corp. of North America TIA UL LLC Whitesell Consulting LLC Project Status: The following is a summary of the status of each Project assigned to TR ANSI/TIA-PN-1083-B, Handset Magnetic Measurement Procedures and Performance Requirements Current Status: AST Technology Labs submitted a contribution that provided information and measurements for testing HAC performance with speech Vs. testing with tones. The results showed that there will be a need to change performance requirements for SNR when testing with speech. This contribution also revealed the need to perform similar comparison tests for distortion with tones and with a pulsed 1/3 rd octave stimulus signal. Editor (James Bress, AST Technology Labs) will revise draft per the recommendations made during the meeting. New business: How to state TIA-1083 wideband compliance. Agreed to use the same statements as developed for TIA-920 which require meeting wideband if a wideband capability exists, and also provides for specific wording that can be used in a test report if only narrowband is tested or only narrowband is compliant. TIA-1083-A hearing aid buzz reports from people in the field. Steve Whitesell will report back on further investigation into the details and issues. PSAPs (Personal Sound Amplification Products) are a potential product for which the concepts developed in the TIA-4953 standard for amplified telephones could be applied to PSAP devices. 8

10 The working group expressed interest in the possibility of developing such a standard but also agreed there will be a need to have the involvement of some PSAP manufacturers. Chair, James Bress will inform Brian Scarpelli that the working group concurs on the need for PSAP manufacturer involvement to ask Brian to try to obtain interested PSAP parties. There was also a discussion on including in-line amplifiers in an amplified products standard. There was a consensus that this was a good idea and also a consensus that this effort will need to have manufacturer involvement. The working group reviewed the HLAA website and revealed the need to have the HLAA website reference TIA standards such as TIA-1083, TIA-4953, and TIA The FCC accessibility clearinghouse website was also reviewed. There was a discussion regarding a potential project to list wireline products on the FCC clearinghouse website. This effort would likely require developing a list of features that define accessibility for the product types listed SUMMARY OF TR during TR41.3 meeting: No votes or motions recorded. 9

11 d. TR-41 AD-HOC: TR-41 Outreach Chair: James Bress, AST Technology Labs No new progress on this effort was reported or discussed. 10

13 TSB-31-D-Addendum-3: Test methods for the TIA-968-B2. b. Industry Canada Jason Nixon (See separate report in TR IndustryCanadaActivityReport.DOC) TAPAC (Terminal Attachment Programme Advisory Committee) o On January 16, 2014 Industry Canada (IC) and TAPAC members agreed to adopt a forward-looking approach of pointing CS-03 technical requirements to the equivalent sections of ANSI/TIA-968 and other applicable U.S. standards on an as required basis. o A TAPAC ad-hoc committee was established to develop guidelines (already posted on the IC website) on how to make amendments to the CS-03 standard as they arise. Below the criteria approved: For modifying existing requirements: 1. changes to wording/numerical references only if changes are minor editorial/technical (e.g., 50 to 100W), or 2. use pointers (i.e., TIA-968 or other applicable standard) to minimize editorial efforts, or 3. use Canadian text where TIA-968 or other applicable standards do not apply. New activities: o For creating new requirements: 1. use pointers (i.e., TIA-968 or other applicable standard) or 2. add Canadian text where TIA-968 or other applicable standards do not apply. Amendment to DC-01. DC-01 (Declaration of Conformity and Registration of Terminal Equipment) describes the procedure to be followed by telecom terminal equipment suppliers when making their declaration of conformity and registering their equipment with IC. On January 16, 2014 IC sought comments from the TAPAC members on draft amendment to DC-01. Main changes include: 1. Section 6.3 Technical Brief (Modified): reflects CB Notice requirements to submit compliance folder at the time of registration 2. Annex II: Test Report Cover Sheet (modified): re-located from Annex I, it includes CS-03 specification details and attestation 3. Annex IV: Test Report Requirements (New): it includes listing of test report requirements. The deadline for receiving comments on DC-01 from TAPAC members has passed (January 31, 2014). IC is in the process of reviewing comments received. DC-01 is planned to be published in March New Publications: o CB Notice ; November 26, 2013: Implementation of Canada-Israel MRA Phase I.
