1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0600010.04.2011 OPERATIONAL VIBRATION REQUIREMENTS FOR COMMUNICATIONS EQUIPMENT ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the informat

2、ion, entertainment and communications industry. More than 200 companies actively formulate standards in ATIS Committees, covering issues including: IPTV, Cloud Services, Energy Efficiency, IP-Based and Wireless Technologies, Quality of Service, Billing and Operational Support, Emergency Services, Ar

3、chitectural Platforms and Emerging Networks. In addition, numerous Incubators, Focus and Exploratory Groups address evolving industry priorities including Smart Grid, Machine-to-Machine, Connected Vehicle, IP Downloadable Security, Policy Management and Network Optimization. ATIS is the North Americ

4、an Organizational Partner for the 3rd Generation Partnership Project (3GPP), a member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications Sectors, and a member of the Inter-American Telecommunication Commission (CITEL). ATIS is accredited by the

5、 American National Standards Institute (ANSI). For more information, please visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer.

6、 Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views

7、and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing

8、, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an

9、 interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revi

10、sed or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the Ame

If testing is performed with pre-release hardware and changes occur prior to release, the changes must be analyzed to determine if they may reasonably impact the outcome of the tests. If a signific

15、ant impact is indicated, the testing shall be repeated on released hardware. 4.1 Equipment Test Categories and Configurations Equipment being subjected to operational vibration testing shall be defined into one of the following categories. Only the test method and acceptance criteria for the selecte

16、d category shall be applied throughout the testing. NOTE: These categories and configurations are taken from ATIS-0600329.2008 and can be performed in conjunction with earthquake resistance testing. 4.1.1 Indoor Equipment Category A Shelf level equipment 100 Bandwidth 5 Hz Overall grms 1 dB Sinusoid

17、al Vibration The tolerance allowed for vibration is 1 dB Frequency 1% 5 Test Matrix Random vibration is usually considered to represent a more realistic vibration characteristic compared with sinusoidal. Random vibration shall be used as the environmental parameter unless significant sinusoidal vibr

18、ation is known to be present in a particular application/installation. In this case, it may be desirable to test the equipment using these sinusoidal waveforms, especially if it cannot be determined if the resonant frequencies of the equipment are outside of the known vibration frequencies. In all c

19、ases, pole mounted equipment shall be tested to the sinusoidal vibration requirement.

Vibration Control System The vibration control system shall be capable of producing a random vibration signal with Gaussian distribution over

23、the range of 4 to 200 Hz with a tolerance of 3 dB. The resolution of the random analysis shall be no greater than 5 Hz. If using a digital analyzer, the digitizing rate shall be 200 Hz with a total storage capacity of 30 seconds, real time. The vibration control system should be capable of accepting

24、 a correction factor to accept variances in accelerometer outputs. 6.1.2 Support Equipment Support equipment should be appropriate for controlling, powering, or monitoring system performance. The equipment should be capable of monitoring degradations in performance or service as appropriate for the
