Appendix 7A

Telecommunications Products Accessibility Checklist

Use this as a tool for high–level guidance in determining if a telecommunications product is compliant or accessible.


Requirement Number

Requirement Summary

Yes, No, or N/A



TTY Connections and Microphones. Telecommunications products or systems that provide telephone functions (i.e., 2–way voice communication) and which do not themselves provide TTY functionality must provide a standard non–acoustic connection point for TTYs. Microphones must be capable of being turned on and off to allow the user to intermix speech with TTY use (§1194.23, Provision a).




TTY Signal Protocols. Telecommunications products that provide telephone functions (i.e., 2–way voice communication) must support all commonly used cross–manufacturer nonproprietary standard TTY signal protocols (§1194.23, Provision b).




Voice Mail, AutoAttendant, and Interactive Voice Response (IVR) Systems. Voice mail, auto–attendant, and interactive voice response telecommunications systems must be usable by TTY users with their TTYs. (§1194.23, Provision c).




Time Interval Alerts for IVR Systems. Voice mail, messaging, auto–attendant, and interactive voice response telecommunications systems that require a response from a user within a time interval must give an alert when the time interval is about to run out and must provide sufficient time for the user to indicate more time is required (§1194.23, Provision d).




Caller ID and Similar Functions. Where provided, Caller ID and other telephone function information that is available to other users of the same system must be provided to TTY users of that system as well. Such users may not be able to see the display of that information (§1194.23, Provision e).




Volume Control. For transmitted voice signals, telecommunications products that provide telephone functions must provide a gain adjustable up to a minimum of 20 dB. For incremental volume control, at least one intermediate step of 12 dB of gain must be provided (§1194.23, Provision f).




Automatic Volume Reset. If a telecommunications product that provides telephone functions allows a user to adjust the receive volume, a function must be provided to automatically reset the volume to the default level after every use (§1194.23, Provision g).




HearingAid Compatibility. Where a telecommunications product delivers output by an audio transducer that is normally held up to the ear, a means for effective magnetic wireless coupling to hearing technologies must be provided (§1194.23, Provision h).




Minimized Interference. Interference with hearing technologies (including hearing aids, cochlear implants, and assistive listening devices) must be reduced to the lowest possible level that allows a user of hearing technologies to use the telecommunications product (§1194.23, Provision i).




Transmission/Conducting Information. Products that transmit or conduct information or communication must pass through cross–manufacturer, nonproprietary, industry–standard codes, translation protocols, formats, or other information necessary to provide the information or communication in a usable format. Technologies that use encoding, signal compression, format transformation, or similar techniques must not remove information needed for access or must restore it upon delivery (§1194.23, Provision j).




Controls and Keys. Products which have mechanically operated controls or keys, must comply with the following four requirements (§1194.23, Provision j): (1) Controls and keys must be tactilely discernible without activating the controls or keys. (2) Controls and keys must be operable with one hand and must not require tight grasping, pinching, or twisting of the wrist. The force required to activate controls and keys must be 5 lbs. (22.2 N) maximum. (3) If key repeat is supported, the delay before repeat must be adjustable to at least 2 seconds. Key repeat rate must be adjustable to 2 seconds per character. (4) The status of all locking or toggle controls or keys must be visually discernible, and discernible either through touch or sound.
