This document is an addendum to

27、TIA TSB-31-D, Telecommunications Telephone Terminal Equipment Rationale and Measurement Guidelines for U.S. Network Protection. It was developed to revise a number of incorrect cross references to TIA-968-B, clarify grounding requirements for longitudinal voltage measurements, remove the test proced

28、ures and REN calculation information for Type B ringing in conjunction with the changes being made by Addendum 3 to ANSI/TIA-968-B, and add DSL FAST measurement procedures. There is also a correction to TIA TSB-31-D-2 contained within this addendum. It has been clearly identified when this addendum

29、is modifying the text of TSB-31-D-2. This addendum was produced by Subcommittee TR-41.9, Technical and Administrative Regulatory Considerations. It was developed in accordance with TIA procedural guidelines, and represents the consensus position of the Subcommittee, which served as the formulating g

30、roup. It also received the concurrence of Engineering Committee TR-41, Performance and Accessibility for Communications Products. The leadership of the TR-41.9 Technical and Administrative Regulatory Considerations Subcommittee (Interim Chair: Jason Nixon, Innovation, Science and Economic Developmen

31、t Canada) acknowledges the written contributions provided by the following individuals in the development of this addendum.

32、ell Suggestions for improvement of this standard are welcome. They should be sent to: Telecommunications Industry Association Technology and Standards Department Suite 200 1320 North Courthouse Road Arlington, VA 22201 ( http:/www.tiaonline.org ) TSB-31-D-4 1 1. SCOPE This addendum provides changes

33、to TSB-31-D, Telecommunications Telephone Terminal Equipment Rationale and Measurement Guidelines for U.S. Network Protection and to its addendum TSB-31-D-2. Where the text of TSB-31-D-2 is modified in clause 2 it is clearly identified. Clause 2 of this document provides the corrections to numerous

34、clauses within TSB-31-D and TSB-31-D-2. Clause 3 of this document provides revised text for the grounding requirements of sub-clause 9.15.8 and 9.17.8 of TSB-31-D to clarify that any metal components of a device not normally connected to ground should not come in contact with the ground plane during

35、 testing. Clause 4 of this document provides changes to sub-clause 5.5, Suggested Equipment List (SEL) of TSB-31-D and provides changes to the following ringing-signal-related sub-clauses under Clause 11, ON HOOK IMPEDANCE LIMITATIONS of TSB-31-D: Sub-clause 11.2, DC Current During Ringing Sub-claus

36、e 11.3, AC Impedance During Ringing Sub-clause 11.4, REN Calculation. Clause 5 of this document provides completely new sub-clauses to add the test methods for assessing DSL FAST technology to TSB-31-D. The other clauses and sub-clauses in TSB-31-D are not affected. For the changes provided in Claus

37、e 2, 3 and 4, additions to the text are shown underlined and deletions are shown using strikeout. The completely new sub-clause text in Clause 5 is not otherwise marked. Words that appear in underlined italics are intended as instructions to the reader. 2. MODIFICATIONS TO EXISTING TSB-31-D TEXT 2.1

38、 Changes to clause 3, REFERENCES Modify the following reference in Section 3: 24. TIA/TSB-168-B (2008)TIA-168-C (October 2015), Telecommunications Telephone Terminal Equipment Labeling Requirements 2.2 Changes to sub-clause 6.5, Telephone Line Surge - Type B, Metallic Modify sub-clause 6.5.8 as foll

39、ows: (4) The surge generator waveform parameters specified are based on an analysis of the surge generator circuit of ITU Recommendation K.21. This recommendation specifies a nominal open circuit voltage waveform of 10 microseconds (s) x 700 microseconds (s). Commercial surge generators are generall

40、y built to the ITU Recommendation and the 10 microseconds (s) x 700 microseconds (s) waveform provided is within TSB-31-D-4 2 the tolerances of the 9 microseconds (s) x 720 microseconds (s) open circuit waveform specified in TIA-968-B subclauses 4.1.2.1.1 4.1.2.2.14.1.3.1 and 4.1.3.2. Surge generato

41、rs conforming to the ITU Recommendation also meet TIA-968-B subclauses 4.1.2.1.1 4.1.2.2.14.1.3.1 and 4.1.3.2. 2.3 Changes to sub-clause 8, Hazardous Voltage Limitations Modify sub-clause 8.4 as follows: 8.4 Hazardous Voltage Limitations, DID TIA-968-B, 5.1.17.35.1.17.6 Modify sub-clause 8.9 as foll

42、ows: 8.9 Intentional Operational Paths to Ground TIA-968-B, 4.3.5.14.3.4.1 2.4 Changes to sub-clause 9, Signal Power Limitations Modify sub-clause 9 as follows: 9 SIGNAL POWER LIMITATIONS TIA-968-B, 4.5 Modify sub-clause 9.1 as follows: 9.1.4 Equipment States Subject to Test Test any off-hook state

43、of the EUT that transmits signals to the network that are not intended for network control. For an EUT that does not normally transmit signals toward the network interface in the off-hook state, the idle (nontransmitting) state is to be tested. For data signals, the EUT is tested in accordance with

44、subclause 8.49.4. 9.1.8 Comments (3) As mentioned in subclause 9.1.1, the level of live-voice signals areis not covered regulated under 47 C.F.R. Part 68by TIA-968-B. Recorded or synthesized signals are not live-voice signals and, as such, are coveredregulated by 47 C.F.R. Part 68TIA-968-B. Typicall

45、y there are three types of signals to consider: Modify sub-clause 9.4 as follows: 9.4.1 Background EUT with through-transmission paths that may be connected to data equipment are not to use the fixed loss loop or programmed data jack configurations unless they are approved in accordance with Section

46、 4.4.2.25.1.2.7 of TIA-968-B. The rule restricts the use of the fixed loss loop and programmed data jack configurations. These jack configurations are to be used only on equipment specifically designed for data signals with power levels that comply with Section 4.4.2.25.1.2.7 of TIA-968-B. Modify sub-clause 9.5 as follows: 9.5 Voiceband Signal Power - Data TIA-968-B, 4.4.2.25.1.2.7
