Title III Technical Assistance Manual (with 1994 supplement)

III−4.3420 Outgoing calls by customers, clients, patients, or participants. On the other hand, TDD's must be provided when customers, clients, patients, or participants are permitted to make outgoing calls on "more than an incidental convenience basis. " For example, TDD's must be made available on request to hospital patients or hotel guests where in-room phone service is provided. A hospital or hotel front desk should also be equipped with a TDD so that patients or guests using TDD's in their rooms have the same access to in-house services as other patients or guests.

It is the hotel's or hospital's responsibility to monitor requests for TDD's to ensure that it has a sufficient supply of such devices. The facility should acquire what it reasonably predicts will be an adequate number of TDD's, and then acquire additional TDD's if experience shows that an increase is necessary to meet actual demand.

Newly constructed hotels must have a certain number of rooms that are accessible to persons who are deaf or hard of hearing (the exact number is dependent on the number of rooms in the hotel). This number of rooms is a useful reference point for a facility attempting to gauge the number of TDD's necessary for effective communication.
