Provide visual information through at least one mode in auditory form.(ii) Availability of visual information for low vision users. Provide visual information through at least one mode to users with visual acuity between 20/70 and 20/200 without relying on audio.(iii) Access to moving text. Provide moving text in at least one static presentation mode at the option of the user.(iv) Availability of auditory information. Provide auditory information through at least one mode in visual form and, where appropriate, in tactile form.(v) Availability of auditory information for people who are hard of hearing. Provide audio or acoustic information, including any auditory feedback tones that are important for the use of the product, through at least one mode in enhanced auditory fashion (i.e., increased amplification, increased signal-to-noise ratio, or combination).(vi) Prevention of visually-induced seizures. Visual displays and indicators shall minimize visual flicker that might induce seizures in people with photosensitive epilepsy.(vii) Availability of audio cutoff. Where a product delivers audio output through an external speaker, provide an industry standard connector for headphones or personal listening devices (e.g., phone-like handset or earcup) which cuts off the speaker(s) when used.(viii) Non-interference with hearing technologies. Reduce interference to hearing technologies (including hearing aids, cochlear implants, and assistive listening devices) to the lowest possible level that allows a user to utilize the product.(ix) Hearing aid coupling. Where a product delivers output by an audio transducer which is normally held up to the ear, provide a means for effective wireless coupling to hearing aids.(3)Real-Time Text. Voice communication services subject to this part that are provided over wireless IP facilities and handsets and other text-capable end user devices used with such service that do not themselves provide TTY functionality, may provide TTY connectability and signal compatibility pursuant to paragraphs (b)(3) and (4) of this section, or support real-time text communications, in accordance with 47 CFR part 67.(b) The term compatibility shall mean compatible with peripheral devices and specialized customer premises equipment commonly used by individuals with disabilities to achieve accessibility to telecommunications services, and in compliance with the following provisions, as applicable: (1) External electronic access to all information and control mechanisms. Information needed for the operation of products (including output, alerts, icons, on-line help, and documentation) shall be available in a standard electronic text format on a cross-industry standard port and all input to and control of a product shall allow for real time operation by electronic text input into a cross-industry standard external port and in cross-industry standard format. The cross-industry standard port shall not require manipulation of a connector by the user.(2) Connection point for external audio processing devices. Products providing auditory output shall provide the auditory signal at a standard signal level through an industry standard connector.(3) TTY connectability. Products which provide a function allowing voice communication and which do not themselves provide a TTY functionality shall provide a standard non-acoustic connection point for TTYs. It shall also be possible for the user to easily turn any microphone on and off to allow the user to intermix speech with TTY use.(4) TTY signal compatibility. Products, including those providing voice communication functionality, shall support use of all cross-manufacturer non-proprietary standard signals used by TTYs.(5)TTY Support Exemption. Voice communication services subject to this part that are provided over wireless IP facilities and equipment used with such services are not required to provide TTY connectability and TTY signal compatibility if such services and equipment support real-time text, in accordance with 47 CFR part 67.(c)The term customer premises equipment shall mean equipment employed on the premises of a person (other than a carrier) to originate, route, or terminate telecommunications. For purposes of this part, the term customer premises equipment shall include equipment employed on the premises of a person (other than a carrier) that is specially designed to provide interconnected VoIP service and that is needed for the effective use of an interconnected VoIP service.(d) The term disability shall mean a physical or mental impairment that substantially limits one or more of the major life activities of an individual; a record of such an impairment; or being regarded as having such an impairment.(e)The term interconnected VoIP service shall have the same meaning as in § 9.3 of this chapter.(f) The term manufacturer shall mean an entity that makes or produces a product.(g) The term peripheral devices shall mean devices employed in connection with equipment covered by this part to translate, enhance, or otherwise transform telecommunications into a form accessible to individuals with disabilities.(h) The term readily achievable shall mean, in general, easily accomplishable and able to be carried out without much difficulty or expense. In determining whether an action is readily achievable, factors to be considered include:(1) The nature and cost of the action needed;(2) The overall financial resources of the manufacturer or service provider involved in the action (the covered entity); the number of persons employed by such manufacturer or service provider; the effect on expenses and resources, or the impact otherwise of such action upon the operations of the manufacturer or service provider;(3) If applicable, the overall financial resources of the parent of the entity; the overall size of the business of the parent entity with respect to the number of its employees; the number, type, and location of its facilities; and(4) If applicable, the type of operation or operations of the covered entity, including the composition, structure and functions of the workforce of such entity; and the geographic separateness, administrative or fiscal relationship of the covered entity in question to the parent entity.(i) The term specialized customer premises equipment shall mean customer premise equipment which is commonly used by individuals with disabilities to achieve access.(j)The term telecommunications equipment shall mean equipment, other than customer premises equipment, used by a carrier to provide telecommunications services, and includes software integral to such equipment (including upgrades). For purposes of this part, the term telecommunications equipment shall include equipment that is specially designed to provide interconnected VoIP service and that is needed for the effective use of an interconnected VoIP service as that term is defined in § 9.3 of this chapter.(k)The term telecommunications service shall mean the offering of telecommunications for a fee directly to the public, or to such classes of users as to be effectively available directly to the public, regardless of the facilities used.
