| (b) Telecommunications products that include voice communication functionality shall support all commonly used cross-manufacturer non-proprietary standard TTY signal protocols. |
Supported |
The SX-2000 LIGHT PBX provides analog ports used in the connection of TTY devices. |
| (c) Voice mail, auto-attendant, and interactive voice response telecommunications systems shall be usable by TTY users with their TTYs. |
Not Applicable |
|
| (d) Voice mail, messaging, auto-attendant, and 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. |
Not Applicable |
|
| (e) Where provided, caller identification and similar telecommunications functions shall also be available for users of TTYs, and for users who cannot see displays. |
Supported |
The SX-2000 LIGHT PBX provides this capability through industry-standard analog caller ID functions on dedicated analog ports or by Mitel Superset 4000 series telephones. For more information, please see the response table for the Superset 4000 Series telephones. |
| (f) For transmitted voice signals, 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. |
Not Applicable |
This is a function of the telephone connected to the SX-2000 LIGHT PBX system. For more information, please see the response table for Mitel Superset 4000 Series telephones. |
| (g) If the telecommunications product allows a user to adjust the receive volume, a function shall be provided to automatically reset the volume to the default level after every use. |
Supported |
Volume control is supported by the SX-2000 LIGHT PBX system’s class of services. |
| (h) Where a telecommunications product delivers 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. |
Not Applicable |
This is a function of the Mitel Superset 4000 series telephones connected to the SX-2000 LIGHT PBX system. For more information, please see the response table for the Superset 4000 Series telephones. |
| (i) Interference to hearing technologies (including hearing aids, cochlear implants, and assistive listening devices) shall be reduced to the lowest possible level that allows a user of hearing technologies to utilize the telecommunications product. |
Not Applicable |
This is a function of the Mitel Superset 4000 series telephones connected to the SX-2000 LIGHT PBX system. For more information, please see the response table for the Superset 4000 Series telephones. |
| (j) Products that transmit or conduct information or communication shall pass through cross-manufacturer, non-proprietary, industry-standard codes, translation protocols, formats or other information necessary to provide the information or communication in a usable format. Technologies, which use encoding, signal compression, format transformation, or similar techniques shall not remove information needed for access or shall restore it upon delivery. |
Supported |
There is no characteristic of the SX-2000 LIGHT PBX that would interfere with the transmitted and received Baudot tones used by US-standard TTYs. |
| (k)(1) Products, which have mechanically operated controls or keys, shall comply with the following: controls and keys shall be tactilely discernible without activating the controls or keys. |
Supported |
The control keys on the SX-2000 LIGHT PBX are laid out in a manner that enables visually impaired users to navigate them easily. These function keys are tactilely discernible based on uniquely shaped keys or reference points on the maintenance panel. |
| (k)(2) Products, which have mechanically operated controls or keys, shall comply with the following: controls and keys shall be operable with one hand and shall not require tight grasping, pinching, twisting of the wrist. The force required to activate controls and keys shall be 5 lbs. (22.2 N) maximum. |
Supported |
The force required to activate the SX-2000 maintenance panel switch will be 2.8 newtons (10 ounces) with a tolerance of +/- 0.7 newtons (1.9 ounces). |
