I have done a bit of drafting to improve our discussions. There is still a lot to work out but take a look at this. The underlined text is new wording, the [x] text would be deletions from current text.
See you at 2 pm.
.2-E - Volume (Gain)
For incoming voice signals:
1 Users must be able to adjust the audio output level.
2. Analog line-powered telecommunications products, wireline, and all wireline or VoIP cordless telephones [wireline or VoIP] must comply with FCC regulation Â§68.317 for volume control
3. All cellular phones - TBD
4. Digital [All other telecommunications]products or systems that provide a function allowing voice communication via an audio transducer typically held to the ear with a hand must provide a gain adjustable from the normal unamplified level to at least 18 dB above the normal unamplified level as measured in accordance with the provisions of the FCC regulation Â§68.317 for volume control. The volume at the normal unamplified level setting must also meet the requirement in FCC regulation 68.317.
5. Other products or system that provide a function allowing voice communications should provide adjustable volume up to 18dB.
6. Where additional volume is needed, ...
Advisory Note 1 Volume (gain) on cellular and PCS handsets is currently the focus of review and study in ATIS Incubator. It is recommended that no recommendation at this time be made by the TEITAC, but rather, the recommendations from the study can be given to the Access Board at a later time.
Advisory Note 2 There are other digital products and systems such as digital telephones and systems that draw from Ethernet, as well as laptop telephone emulators which use a headset. None of these choices can be measured using FCC regulation 68.317 for volume control. In the case of laptop telephone emulators, they are typically used with a headset which is an accessory.
Discussion or Rationale:
* Language for cellular phones pending outcome of ATIS Study Group 11 work
* Further research needed for 20 dB requirement
* Review telecoms/communications to be sure requirement is inclusive
