Telecommunications Relay Services and Speech-to-Speech Services - E911 Requirements

Final Rule SUMMARY: In this document, the Commission adopts a system for assigning users of Internet-based Telecommunications Relay Services (TRS), specifically Video Relay Service (VRS) and Internet Protocol (IP) Relay, ten-digit telephone numbers linked to the North American Numbering Plan (NANP). This numbering system will further the TRS functional equivalency mandate by ensuring that Internet-based TRS users can be reached by voice telephone users in the same way that voice telephone users are called. The measures the Commission adopts also are intended to ensure that emergency calls placed by Internet-based TRS users will be routed directly and automatically to the appropriate emergency services authorities by Internet-based TRS providers.
