Criteria Supporting Feature Remarks and Explanations (a) Telecommunications products or systems Not Applicable provide a function allowing voice communication and which do not themselves provide a TTY functionality shall provide a standard connection point for TTYs. Microphones shall be capable of being turned on and off to allow the user to intermix speech with TTY use. (b) Telecommunications products which include Not Applicable voice communication functionality shall support all commonly used cross-manufacturer standard TTY signal protocols. (c) Voice mail, auto-attendant, and interactive Not Applicable voice response telecommunications systems shall be usable by TTY users with their TTYs. (d) Voice mail, messaging, auto-attendant, and Not Applicable interactive voice response telecommunications systems that require a response from a user within a time interval, shall give an alert when the time interval is about to run out, and shall provide sufficient time for the user to indicate more time is required. (e) provided, caller identification and similar Not Applicable telecommunications functions shall also be available for users of TTYs, and for users who cannot see displays. (f) For transmitted signals, Not Applicable telecommunications products shall 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 shall be provided. (g) If the telecommunications product allows a Not Applicable user to adjust the receive volume, a function shall be provided to automatically reset the volume to the default level after every use. (h) Where a telecommunications product delivers Not Applicable output by an audio transducer which is normally held up to the ear, a means for effective magnetic wireless coupling to hearing technologies shall be provided. (i) Interference to hearing technologies (including Not Applicable hearing aids, cochlear implants, and assistive listening devices) shall be reduced to the lowest
