• A. Indirect access
• B. Interoperable access
• C. Relay access
• D. Direct access

Answer: (D)

Direct access means PSAPs have a direct connection to receive TTY calls, without going through an outside relay service or third-party. This ensures real-time, unbroken text communication between the caller and the dispatcher, reducing delays and the risk of miscommunication that can happen when a relay operator handles the call. It also improves reliability and accountability in documenting the interaction.

Indirect access would rely on a relay or third party to connect the call, which can introduce delays and potential errors. Interoperable access focuses more on compatibility between systems or agencies rather than the direct routing of a TTY call. Relay access explicitly involves routing the call through a relay service, which contrasts with direct access.
