Proposal for 5F -Video support

Current text:
Telecommunications products or systems which have the capacity to transmit
video, text, and voice communications must support internet protocol text
and voice communications in X format, and they must have sufficient
transmission bandwidth capacity to support video communication such as video
relay and point to point video communications.

Problems:
1. The experienced quality level should be defined, not the bandwidth.
2. It is products supporting video that shall meet these requirements.
Support for text and audio is a follow-on requirement.
3. The purpose for the quality requirement should be stated.

These considerations lead to new proposed text:

Telecommunications products or systems which have the capacity to transmit
video, real-time text, and voice communications must support
interoperability with internet protocol text, video and voice communications
in X format, and they must have sufficient quality and fluency to support
video communication for sign language. lip reading and other personal
communication such as video relay and point to point video communications.

See if this summarizes what we've been discussing:

Base requirement - E&IT that provides a function allowing voice
communication via audio transducer typically held to the ear (except those
exempted below) must provide a gain adjustable from the normal unamplified
level to at least 15-16 dB above the normal unamplified level as measured in
accordance with the provisions of the FCC regulation §68.317 for volume
control. The volume at the normal unamplified level setting must also meet
the requirement in FCC regulation 68.317.

Exception 1 - Analog line-powered E&IT and battery powered cordless
telephones must comply with FCC regulation §68.317 for volume control.

Exception 2 - Cellular phones

Gentlepeople: -


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 §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
§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
