Section 890.120  Equipment and Maintenance

a)         TDDs must satisfy the following specifications:

1)         Portability − must be portable to the extent that the TDD can be used at various public telephone locations within the building/terminal, if the TDD is not already located adjacent to a public telephone.

2)         Display − must have an internal printer which provides a paper printout of the conversation.

3)         Compatibility − the acoustic coupler of the TDD and the handset of the telephone must be compatible or the TDD must otherwise be compatible for use with the telephone.

b)         If an electrical outlet is not located adjacent to the available public telephones, the TDD(s) must be battery powered.

c)         A level, flat surface immediately adjacent to at least one public telephone used for TDDs must be provided, so as to accommodate the placement of the TDD, either permanently fixed or portable.  The handset cord/cable length of telephones must be sufficient to allow placement of the handset in the acoustic coupler while the TDD is on the adjacent flat surface.

d)         The operating authority is responsible for maintaining the TDD(s) in working order and for the costs of the maintenance.
