17、dated creation of the Administrative Council for Terminal Attachments (ACTA). In 47 CFR 68.7(b) ACTA was charged to adopt and publish technical criteria to prevent harms to the telephone network submitted to it by standards development organizations accredited by the American National Standards Inst
18、itute (ANSI). This document was created for submission to ACTA in accordance with 47 CFR 68.604. The latest requirements adopted by ACTA may be found at www.part68.org. This document is an addendum to TIA-968-A, Telecommunications Telephone Terminal Equipment - Technical Requirements for Connection
19、of Terminal Equipment to the Telephone Network. This addendum adds requirements for VDSL2 (very high speed digital subscriber line 2) terminal equipment . This addendum was produced by working group TR-41.9.1 of subcommittee TR-41.9, Technical and Administrative Regulatory Considerations. It was dev
20、eloped in accordance with ANSI and TIA/EIA procedural guidelines and represents the consensus position of the Working Group and its parent subcommittee, which served as the formulating group. It has also received the concurrence of Engineering Committee TR-41, User Premises Telecommunications Requir
21、ements. Committee approval of this standard does not necessarily imply that all members voted for its approval.
