INTRODUCTION

1. General AT&T is issuing this document to assist OEM and Product Suppliers in there effort to bring new products to market at AT&T.

1.1. Requirements and Objectives The objective of this AT&T TP76205 is to provide the basic standards for product suppliers to follow for the configuration and construction of EEE / Cs. The following Telcordia documents are considered the basic standards: Telcordia GR3108 issue 2, GR487 issue 3, GR950 issue 1 GR-3142 Issue 1. In addition to the Telcordia standards mentioned above, the electronics equipment, Network Elements, and hardware contained within such EEE / Cs must also meet AT&T TP76200 and/or other applicable AT&T TP documents.

1.2. Purpose The purpose of this document is to provide product suppliers with the Telcordia documents, standards, and AT&T requirements that may differ from or exceed Telcordia Generic Requirements (GR). A product's compliance with the requirements and objectives of this document will not be the sole basis for the acceptance of the product. However, noncompliance with one or more of the requirements or objectives of this document may be the basis for a product's denial of approval for use.

1.3. Scope Unless otherwise stated, the requirements contained herein apply to EEE / C systems, and their supporting equipment intended for installation in all of AT&T network outside of the Telecom Central Office (CO) and not within the customers building. This includes AT&T mobility. Requirements for network electronics that may be deployed within the EEE/C are covered by ATT-TP-76200 and are excluded from this document. This excludes equipment buildings, equipment areas within buildings, controlled environmental vaults and customer locations.

1.4. Definitions A. The term product supplier / vendor / OEM as used throughout this document refers to the equipment manufacturer or agent of the equipment manufacturer, whichever is appropriate for the product being considered. B. The term company representative / AT&T as used throughout this document refers to the AT&T OPERATIONS, employee representing AT&T OPERATIONS. C. The term Electronic Equipment Enclosures / Cabinet (EEE/C) as used throughout this document refers to the AT&T metallic or non metallic containers suitable for use outside the four walls of a telecommunication building that may contain Network and/or Mobility electronic elements that provide but are not limited to Voice, Data, and Entertainment services. D. Requirements are those product features that must be provided by the equipment manufacturer. The words "shall" and "must" are used throughout this document to identify requirements. E. Objectives are product features that are desired for the long term use or application. The word should is used throughout this document to identify objectives. F. The term Network as used throughout this document refers to the AT&T Telecom network that provides but is not limited to Voice, Data, and Entertainment. G. The term Mobility as used throughout this document refers to the AT&T wireless network or cellular equipment that provides but is not limited to Voice, Data, and Entertainment.

H. The term Radio Frequency (RF) Backhaul as used throughout this document refers to the AT&T wireless network backhaul equipment that provides but is not limited to Voice, and Data.

1.5. AT&T-TP76205 Internet Web Site Copies of this document and general information about AT&T OPERATIONSs environmental equipment standards may be found at. https://ebiznet.sbc.com/sbcnebs/

1.6. Product Evaluation Process AT&T requires GR test reports be forwarded to AT&T OPERATIONS for review before the product will be approved for use. To meet the needs of the business, AT&T may authorize an exception, with the submission of a Letter Of Attestation from the OEM for incomplete test results. Completed test reports are still required to be submitted in a time frame negotiated with the AT&T SME, see list in item 8.

1.7. Requirement Levels Equipment must demonstrate conformance to subsets of requirements contained in AT&T TP76205 depending on the intended application and deployment environments of the equipment. The Product Supplier shall provide GR3108 or GR950 test results for the electronics and service effecting components intended for use within GR487 or GR950 structure and or any requirements that exceed GR3108. Equipment must conform to requirements (R) for each location and/or application for which it is intended. OUTSIDE PLANT (OSP) Typically OSP network locations are between the outside of the four walls of the COs, Non-CO buildings and Customer Premises. There are four levels of OSP environments: OSP Class One refers to Controlled protected environments typically OSP Huts, CEVs, and other OSP enclosures with active HVAC environment per Telcordia GR-3108-CORE ISSUE 2. OSP Class Two refers to Protected equipment in outside environment, per Telcordia GR-3108-CORE ISSUE 2. OSP Class Three refers to Protected equipment in outside severe environment per Telcordia GR-3108-CORE ISSUE 2. OSP Class Four refers to Unprotected environment directly exposed to the weather, per Telcordia GR-3108-CORE ISSUE 2.

1.8. Product Change Notices (PCNs) Reference GR-209-CORE Issue 5, February 2006. PCNs must be evaluated for their effect on the equipments AT&TTP-76205 compliance.

1.8.1. Letter of Attestation. When it is determined by the manufacturer, using sound engineering judgment that a hardware or software change does not impact the equipments AT&T-TP-76205 compliance, the manufacturer may submit a letter of attestation to this effect.

NOTE: Except when it is obvious that the PCN will not affect the equipments compliance. AT&T OPERATIONS recommends that an accredited, third party, independent laboratory evaluate whether testing is required to verify compliance.

1.8.2. Retesting Requirement.

When the manufacturer, a test lab or AT&T OPERATIONS determines that the PCN may affect the equipments AT&TTP- 76205 compliance, the modified equipment must be tested per AT&T-TP-76205

NOTE: Depending on engineering judgment, not all requirements may need to be tested.

2. AT&T OPERATIONS Requirements 2.1. Basic Test Lab safety requirements The equipment under test shall provide for the safety of personnel and property. However, due to needs of the business and the fact that the lab is staffed by personnel trained to work with prototype equipment, there are times when it may be necessary for equipment to be placed into labs that has not been verified

in compliance to safety standards. In those cases, it is incumbent upon the manufacturer to assure the equipment is safe to operate. If equipment does not meet the above objective, the manufacturer shall submit a notarized Letter of Attestation (LOA) that the equipment meets industry electrical safety, electromagnetic emissions and fire safety standards.

NOTE: All applicable AT&T-TP-76205, TP76200 and AT&T-TP-76450 requirements must be evaluated as in conformance prior to deployment into the network.

2.2. Controlled Environmental Remote Terminal Structures (CEVs, Huts, CECs, CUEs, etc) and Customer Premise. This document does not cover technical requirements for RT structures (CEVs, Huts, CECs, CUEs, etc) or network equipment installed at customer premise locations.

6. APPENDIX B: AT&T-TP-76205 PRODUCT CHANGE TEST GUIDELINES 6.1. Purpose The purpose of this appendix is to provide product suppliers a guide to help determine what tests may not need to be performed on a product enhancement to verify conformance to AT&T-TP-76205 Ancillary requirements.

6.2. 5.2. General Some product enhancements are so minor that a complete retest of the product may not be necessary. Typically, when a product supplier requests a re-test waiver to run tests on product enhancements, data comparing the new product to the existing product is submitted to the company representative for evaluation by AT&T Operations. Depending on the product under review, this data may include pictures, descriptions of electrical components, etc. Each AT&T Operations product evaluation subject matter expert (SME) then reviews this data and responds with an assessment of what tests are required. This Appendix is a guideline only. It is the product suppliers responsibility to satisfactorily document that the new product conforms to applicable requirements.
