9 APPENDIX A – ATT-TP-76450 Checklist Instructions and Process

9.2 Purpose The purpose of this appendix is to assist product suppliers with preparing and furnishing equipment documentation to the company representative for product evaluation purposes.

9.3 Scope An evaluation reviews a product against all applicable requirements based on the equipment and its intended use in the network. Unless otherwise stated, all requirements apply to equipment systems and equipment units that will be installed in network equipment buildings and equipment areas within buildings, electronic equipment enclosures such as controlled environment vaults, outside mounted electronic equipment cabinets, and at customer locations.

9.4 Instructions Manufacturer is to complete the ATT-TP-76450 Checklist in Appendix B. Mark the appropriate column in the checklist as follows:  “Yes” indicates that the equipment listed is compliant to the requirement.  “No” indicates that the equipment listed is not compliant to the requirement. Each requirements checked “No” must include an explanatory footnote.  “N/A” indicates that the requirement is not applicable to the equipment listed. Each requirements checked “N/A” must include an explanatory footnote.  If product is ATT-TP-76200 Level 3 or unknown respond to each requirement in the checklist.  If product is ATT-TP-76200 Level 1 or OSP respond only if applicable column is marked “yes”. *If equipment is evaluated by manufacturer as compliant, but deviates in some way from the stated requirement, mark “Part” (partial) in the “No” column and include an explanatory footnote. Explanatory footnotes should be placed in the matrix following the checklist and reference specific requirement numbers for each comment. Forward supporting documentation as required in Section 7.3.

Note: Any No or N/A responses require written detailed in comments and supporting documentation.

9.5 Process Requirements marked “Yes” for compliance will require no further action. Requirements marked “No” for non-compliance will trigger the AT&T SME for the requirement to contact the manufacturer in an effort to resolve the non-compliance. All issues must be resolved before the equipment is approved for use in AT&T. Footnote references for requirements marked “N/A” for not applicable or “Part” for Equipment Interconnection Standards ATT-TP-76450, Issue 17 AT&T Technology Operations June 2016 partially compliant will be reviewed by the AT&T SME for that requirement. The SME may initiate contact with the vendor for further clarification and/or resolution. When compliance/resolution to all requirements is met, the ATT-TP-76450 SPOC will notify the AT&T Product Manager for the equipment that it is compliant. The completed checklist and supporting documentation as required in Section 7.3 shall be uploaded to the AT&T ATT-TP-76200 ATT-TP-76450 Documentation Upload DropBox.

3 SYNCHRONIZATION/EXTERNAL TIMING INTERFACE STANDARDS Please read the text of section 3 completely before proceeding with this section of the questionnaire. If you have any questions about the requirements of this section and its applicability to your DUC, or have suggestions for improving the format of this section, please contact the AT&T Common Systems synchronization SME. Text of explanations to questions posed in the questionnaire should be posted in the Notes section. Rqmt* Description L1 OSP Yes No N/A 3.1.1 Will the DUC, as it will be deployed in the AT&T yes n/a network, require an external frequency timing reference sourced from the site BITS systems? Enter Yes or No. If response is No, explain why the DUC does not require an external frequency timing reference sourced from the site BITS systems (e.g.: asynchronous only applications such as metro Ethernet, asynchronous IP transport, DUC will be line or loop timed, etc.) If yes, proceed to 3.1.2. If no, skip to 3.2.1. 3.1.2 Describe the external timing signal format(s) supported yes n/a (e.g.: DS1, CC, E1, 2048 kHz) in the notes. 3.1.3 Describe the external timing input interface in the notes. yes n/a Include a description of the type of connections (e.g.: wire wrap pins, RJ45), the location of the connections, and the termination impedances supported for each signal format. 3.2.1 Will the DUC, as deployed in AT&T, require a separate yes n/a dedicated GPS antenna and receiver system to supply precision frequency, time, phase, or location synchronization? Enter Yes or No. If the response is Yes, please explain the synchronization requirements or direct the AT&T Common Systems sync SME to supplier documentation submitted in support of this review. 3.3.1 Questions 3.3.1 through 3.3.4 apply to a DUC that utilizes yes n/a a PTP client for the timing solution. Note that the use of PTP may vary depending on the location of the DUC in a CO, MTSO, vs. a remote terminal or base station. Does the DUC, as deployed in AT&T, require PTP for a timing solution? Respond Yes or No. If response is yes, please proceed to 3.3.2. If response is NO, please skip to section 3.4. Equipment Interconnection Standards ATT-TP-76450, Issue 17 AT&T Technology Operations June 2016 3.3.2 Is the PTP client in the DUC compliant to the current yes n/a version of the ITU-T PTP Telecom Profile? Respond Yes or No. 3.3.3 Please describe in the notes the level of precision yes n/a required at the PTP timed DUC in parts per million for frequency, and/or time/phase accuracy for time of day or phase requirements. 3.3.4 Is the PTP client in the DUC compatible with IPv6? yes n/a 3.4.1 Questions 3.4.1 through 3.4.3 apply to a DUC that utilizes yes n/a a NTP client for the timing solution. Does the DUC require NTP to deliver a frequency, time, and/or phase reference to the DUC or downstream connected network elements? Respond Yes or No. 3.4.2 What is the frequency, time, and/or phase accuracy yes n/a required? Please respond in the notes. 3.4.3 Is the NTP source for this DUC and associated platform yes n/a specific to the platform, meaning a dedicated GPS antenna and receiver are required as the NTP source? Respond Yes or No. If the response is Yes, please explain the NTP source requirements or direct the AT&T Common Systems sync SME to supplier documentation submitted in support of this review.
