TTYs complying with Section 11B-704.4 shall be provided in accordance with Section 11B-217.4.
[2010 ADAS] Advisory 217.4 TTYs. Separate requirements are provided based on the number of public pay telephones provided at a bank of telephones, within a floor, a building, or on a site. In some instances one TTY can be used to satisfy more than one of these requirements. For example, a TTY required for a bank can satisfy the requirements for a building. However, the requirement for at least one TTY on an exterior site cannot be met by installing a TTY in a bank inside a building. Consideration should be given to phone systems that can accommodate both digital and analog transmissions for compatibility with digital and analog TTYs.

Where four or more public pay telephones are provided at a bank of telephones, at least one public TTY complying with Section 11B-704.4 shall be provided at that bank.
