Equipment Evaluation Types
New Product (ESR-003 and/or ESR-001)
New Product requirements refer to a subset of requirements that apply to all new
equipment systems proposed for use in the AT&T communications network. New
Products shall be evaluated for compliance to all applicable Level 3 and/or Level 1 testing
and requirements.
Ancillary (ESR-ANC) (Level 1 or 3). Ancillary requirements refer to a subset of
requirements that apply to additions to or changes to equipment previously approved for
use in AT&T.If a change to an existing product, or sub-system of the product, results in
the assignment of a new CLEI code, the product shall be evaluated for compliance to
Ancillary requirements. See Appendix B for guidelines applicable to special
considerations for testing of enhanced products.
Product Change Notices (PCN). PCNs indicate a change to existing equipment that has
been previously evaluated for compliance to this document. PCNs must be evaluated for
their effect on the equipment’s ATT-TP-76200 compliance.
•
When the manufacturer, a test lab or AT&T Services determine that the PCN may
affect the equipment’s ATT-TP-76200 compliance, the modified equipment must be
tested per ATT-TP-76200, Ancillary Requirements (ESR-ANC).
NOTE: Depending on engineering judgment, not all requirements may need to be
tested.
•
When it is determined by the manufacturer, using sound engineering judgment, that
a hardware or software change does not impact the equipment’s ATT-TP-76200
compliance, the manufacturer may submit a letter of attestation to this effect. See
Appendix A, paragraph 16.8.
NOTE: Except when it is obvious that the PCN will not affect the equipment’s
compliance, AT&T Services recommends that an accredited, third party,
independent laboratory evaluate whether testing is required to verify compliance.
Equipment Requirement Levels
Level-One (ESR-001-XXX). Level One refers to a subset of ATT-TP-76200 requirements that
forms the minimum acceptable safety requirements necessary to protect personnel and
the network. Level One is applicable for Collocator’s equipment and may be applicable
for AT&T equipment that is not critical to the network or otherwise specified by AT&T
(e.g. monitoring and test equipment).
Level-Three - (ESR-003-XXX). Level Three refers to the maximum applicable ATT-TP-76200
safety and environmental reliability requirements for equipment deployed in the network.

Outside Plant (OSP/CELL-SITE) – Outside plant part of the network. Typically network
locations between the inside of Network Equipment Space buildings and Customer
Premises Antenna locations. OSP/CELL-SITE equipment shall be Carrier Grade.
Most of World (MoW) - Equipment Deployed Outside the United States:
Equipment Deployed Outside the United States will require verification of compliance to
ATT-TP-76200/ATT-TP76450 per Appendix A and completed MoW Letter of Attestation
per Section 16 Form 16.12.
AT&T Test Laboratory – the primary purposes of lab entry requirements for equipment
under test are to ensure the safety of personnel and property. It is the objective of this
requirement that verification of compliance to industry safety standards be provided for
equipment prior to lab entry. 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 AT&T to allow equipment into its lab 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. AT&T labs will assess
acceptance and test protocols for this equipment on a case-by-case basis.
1) Objective: Prior to entry into AT&T labs, equipment should be compliant to ATT-TP76200 Carrier Grade Level 1 requirements, or Non- Carrier Grade Level 1 requirements,
or be Listed (e.g. UL 60950)
2) Requirement: 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: The above requirements are applicable only for AT&T laboratory testing. All
applicable ATT-TP-76200 and ATT-TP-76450 requirements must be evaluated as in
conformance prior deployment into the network.

Heat Dissipation
A. General Information
AT&T utilizes both the nominal (normal operating) and maximum heat values
(use Watts vs. BTU) for equipment when designing equipment space
infrastructures. The nominal heat value is the primary driver of cooling
requirements. Heat values are documented on the ESP form and, where
required, on the ATIS charts.
ATIS heat reporting charts provide five (5) points of heat. This information
provides a more detailed understanding of the overall equipment cooling
demand.
• Values entered into ESP and ATIS forms may be measured and/or
calculated values.
The configuration of equipment deployed in OSP/CELL-SITE cabinets must be
approved by OSP/CELL-SITE staff prior to approval for use.

PB-free Solder Joint Reliability
This section is intended to identify Solder Joint Reliability (SJR) requirements for equipment
manufactured with PB solder per ATIS-0600019 and ATIS-0600020 standards. These
standards apply to electrical and electronics products, including, but not limited to
telecommunications equipment, sold to AT&T.
Manufacturer shall complete Pb-Free Solder Declaration (PbF Form) paragraph 15.16, and
forward to AT&T.
Per Telcordia Notice to the Industry, November 2006, Reliability Concerns with the use of
Lead (Pb) Free Solder in Telecommunications Products and other sources there is
continuing concern regarding the use of RoHS 6 compliant equipment for
telecommunications applications that require long life and high reliability. RoHS compliant
equipment and equipment components proposed for deployment in AT&T network shall
need to demonstrate reliability of solder joints equal to or greater than that of RoHS 5
equipment.
Demonstration of reliability shall include:
1. Pb free sub-assembly modules (e.g., hard drives, PCI cards, transceivers, etc.) shall
demonstrate compliance to ATIS standard Test Requirements for Pb-Free
Subassembly Modules ATIS-0600019.
Vendor shall complete and return the checklist contained in Section 4.3 of the
ATIS document.
Note: Pb-free SFP/XFP type modules are considered compliant to requirement and do
not need to be submitted for review.
2. Pb free assemblies (e.g., circuit boards, etc.) shall demonstrate compliance to the
ANSI standard Guideline for Pb-Free Assembly Qualification and Test Requirements for

Printed Wiring Board Assemblies, ATIS-0600020. Vendor shall complete and return the
checklist contained in Section 4.3 of the ATIS document 1.
3. Copies of test reports for ATIS standards,
4. All reliability and failure rate information (e.g. FIT data) for the product for all previous
and existing deployments regardless of service provider or geography.
5. Pb-free soldered equipment will be evaluated for approval by AT&T on a case-bycase basis weighing compliance to the above requirements and other risk factors. For
example, deployment in an OSP/CELL-SITE environment, use of large high strain
components (e.g. ceramic BGAs), etc. indicate a higher risk of solder joint failure for
RoHS 6 equipment, while small plug-in sub-assembly components may pose lower
reliability risks.
6. A Solder Joint Reliability Letter of Attestation verifying compliance to ATIS
standards may be submitted in lieu of the above information. See Appendix A, 16.11.
NOTE: The PCN process shall be used for all transitions of existing lead/tin soldered
equipment to Pb-free.
13. Energy Efficiency Testing Requirements
Purpose
The purpose of this Section is to establish energy efficiency testing and reporting

laboratory. The supplier may also provide additional data for configurations different from
those tested by the third party test laboratory.
Telecommunications Energy Efficiency Ratio
The following guidelines will be followed when defining TEER for equipment:
• The scale will be fully defined in the supplemental standards such that typical TEER
values range from 1 to 1000.
• The higher the TEER value, the more energy efficient the equipment is compared to
other like equipment.
• The supplemental standard will define the TEER calculation details.
TEER is the ratio of useful work over energy consumed,
TEER =
UsefulWork
PTEER
.
Application
The standards will be used to establish baselines for minimum acceptable energy efficiency
of network elements. In addition to the General Requirements, the supplemental standards
shall be used to create Telecommunication Energy Efficiency Ratios (TEER) by equipment
type.
The equipment types are currently categorized as Core, Transport, Access, CPE, and Power
Systems based on application and location in the network.
Standards Development
At the time of this issue, ATIS has several standards at various stages of development
ranging from final editing, draft for review, to draft preparation. As ATIS publishes these
and subsequent supplemental energy efficiency standards they shall be adopted first as
objectives and finally as requirements in revisions of this Technical Publication.
Energy Efficiency Report
An Energy Efficiency Report shall be included in any new product evaluation for Carrier
Grade Level 3. A sample TEER reporting form is available from ATIS-0600015.2009. In
addition to this form, data as required for the specific equipment types covered by ATIS0600015.01-.04 shall also be reported.

AT&T Services Documentation Package Evaluation Process
The AT&T Services Common Systems Equipment Evaluation group will review the
equipment Documentation Package. If the equipment cannot be evaluated as compliant
to all applicable requirements, an Initial Letter will be sent to the company representative
specifying the areas that are not evaluated in conformance and what further action is
required of the equipment supplier.
Upon receipt of the Initial Letter, the equipment supplier may forward supplemental data
to or contact the company representative, the AT&T Services Equipment Evaluation
Group Coordinator or a specific SME regarding non-compliance resolution. Contact
information for the Group Coordinator and SMEs is contained in the Initial Letter.
Documentation, electronic, forwarded to AT&T Services containing supplemental data in
response to an Initial Letter should identify the contents of documentation and reference
the Evaluation Log number assigned to the product, the SME who requested the data
and the non-compliance requirement the data is addressing.
The SME(s) who requested the documentation will evaluate supplemental data forwarded
to AT&T Services by the product supplier. If the supplemental data is sufficient to allow
all open areas to be evaluated as in conformance to applicable requirements, a
Notification of Conformance to ATT-TP76200 Report will be sent to the company
representative notifying them that the equipment conforms to requirements. If there are
still open items after supplemental data has been reviewed an Evaluation Status letter
will be sent to the company representative giving the status of the product and what
further action the product supplier needs to take.
AT&T Services Product Evaluation Fast Track Process
AT&T Services has established a fast track process it will use for certain business
opportunities to streamline equipment evaluations and shorten time-to-market intervals.
The process consists of AT&T Services accepting ATT-TP-76200 compliance Letters of
Attestation and minimal product information from equipment suppliers in lieu of the Test
Report Documentation Package described above.
A. ATT-TP-76200 Fast Track General guidelines:
1) The process is an optionally agreed upon business arrangement between AT&T
Services and an equipment supplier.
2) A supplier must have successfully participated in the Test Report Documentation

17. APPENDIX B:
ATT-TP-76200 EQUIPMENT CHANGE TEST GUIDELINES
Purpose
The purpose of this appendix is to provide equipment suppliers a guide to help determine
what tests may not need to be performed on a product enhancement to verify conformance
to ATT-TP-76200 Ancillary requirements.
General
Some equipment enhancements are so minor that a complete retest of the equipment may
not be necessary. Typically, when a equipment supplier requests a re-test waiver to run tests
on equipment enhancements, data comparing the new equipment to the existing equipment
is submitted to the company representative for evaluation by AT&T Services. Depending on
the equipment under review, this data may include pictures, fire load data, descriptions of
electrical components, etc. Each AT&T Services equipment 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 equipment suppliers’ responsibility to satisfactorily
document that the new equipment conforms to applicable requirements. This Appendix only
applies to equipment enhancements to equipment previously evaluated as in conformance
to applicable ATT-TP-76200 requirements and approved for use in AT&T.
Software upgrades/changes shall be evaluated if it involves:
• Additional or revised hardware
• Activation of previously unused hardware
• An increase in the amount of power supplied to the hardware
Retest Guidelines by ATT-TP-76200 Sections
A. Section 2, Electromagnetic Compatibility
Electromagnetic Interference – Emission & Immunity (ATT-TP-76200 Req. 2.4 – 2.5)
•
Equipment suppliers should reassess or retest their equipment’s Emissions and
Immunity performance in accordance with GR-1089 CORE, Section 3.4.7. As part of
their reassessment, equipment supplier shall consider the effects of software changes
on the Emissions and Immunity performance of their equipment.
Lightning, AC Power Faults, Steady State Power Induction, Electrical Safety & DC Potential
Difference (ATT-TP-76200 Req. 2.6 – 2.9).
Copyright ©2014, AT&T . All Rights Reserved.
77
Equipment Physical Design Standards
AT&T Services, Inc.
•
ATT-TP-76200, Issue 19
June 2014
Equipment supplier’s should reassess or retest their equipment’s performance for
Lightning, AC Power Faults, Steady State Power Induction, and Electrical Safety & DC
Potential Difference whenever materials, components, circuit layout or accessibility is
changed. .Equipment should be reassessed or retested when changes in software
activate hardware not previously active or affect the equipment’s ability to the EMC
requirements of ATT-TP-76200 (Req. 2.6 – 9). The equipment’s reassessment or
retesting may include all of the technical requirements in these sections of ATT-TP76200. However, the reassessment or retesting is usually limited to only those
technical requirements effected by the change in the equipment.
B. Section 3, Acoustic Noise (ATT-TP-76200 Section. 3.)
•
Equipment suppliers should reassess or retest their equipment’s Acoustic Noise
performance when a change is made to the equipment’s fan design, fan control system
or a change in the number of fans within the equipment.
C. Section 4, ESD
•
Subsystems should be tested whenever changes are introduced that may alter ESD
susceptibility. Such changes may include a modified printed wiring board, new/or
additional components additional components, changes to the power supply, additional
telecommunications ports, and changes in chassis design, software activation of
existing hardware or increased clock speed.
D. Section 5, Grounding
•
The only Grounding requirements for Ancillary equipment are the short circuit tests.
Embedded ac or dc power supplies should be tested whenever changes are introduced
that could alter these. Such changes may include a modified printed wiring board, new
components or additional components, changes to the power supply, additional
telecommunications ports, changes in chassis design, software activation of existing
hardware or increased clock speed.
E. Section 6, Thermal
F. Temperature and Humidity
If the new equipment is significantly different from existing compliant equipment (e.g.,
different sub components, wiring, spacing, etc.) the previous test data may not be
applicable to the new equipment. In order to be allowed to forego temperature and
humidity testing on a new equipment, the equipment supplier needs to demonstrate to
AT&T Services that the new equipment is physically almost identical to the existing
compliant equipment. This may be done via photographs, written descriptions,
statements, etc.
Heat Dissipation
Copyright ©2014, AT&T . All Rights Reserved.
78
Equipment Physical Design Standards
AT&T Services, Inc.
ATT-TP-76200, Issue 19
June 2014
Heat dissipation should be recalculated whenever a change is introduced that changes
the power usage of the unit.
Airflow Path
Airflow path(s) should be updated whenever a change is introduced that changes the
documented airflow(s) of the unit.
Direction and Velocity (Effective 1/1/2012)
Direction and velocity(ies) of the designated airflow paths should be updated whenever
a change is introduced that changes the documented airflow(s) of the unit.
G. Section 7, DC Power
The equipment supplier may perform an analysis, using good engineering based on
similarities to the existing equipment, predicting the probable conformance of the new
equipment to Ancillary DC Power requirements. This analysis should consider similarities
and differences of electric components, wiring, and power levels. The analysis shall be
submitted to the company representative for review and approval by AT&T Services.
H. Section 8, Airborne Contaminants
In reference to Airborne Contaminants testing, Telcordia GR-1274-CORE, states that “The
qualification test shall be passed once for each new family of printed wiring assemblies.”
Based on Telcordia’s assessment, new assemblies for enhanced equipment need not be
tested for airborne contaminants if they meet the criteria for the same design family of
printed boards, defined as follows:
• A design family consists of printed wiring boards from the same manufacturer; using the
same design rules for minimum line spacing and maximum electric field, and using
components that require the same bias voltages. Within the same design family,
boards shall have the same finish, i.e. they shall all be bare or all be coated with the
same overcoat.
If the equipment supplier does not test some or all of the printed wiring boards in
enhanced equipment, they shall supply a statement affirming that the board(s) not
tested meets the definition for being in the same design family of a equipment
previously approved for use in AT&T. Documentation verifying the conformance of the
tested card must be submitted for review.
I. Section 9, Shock and Vibration
Equipment should be tested whenever changes are introduced that could alter the physical
integrity of the unit.

Section 10, Fire Resistance:
Reasons for Reassessment
Generally, equipment that have been determined to be acceptable for purchase from a fire
resistance perspective do not have to be re-evaluated or retested unless subsequent changes
to the equipment include one or more of the following:
1) A change in the manufacturer's unique equipment identifier.
2) A modification to an equipment assembly's enclosure that increases ambient air
circulation.

Acceptance of new Equipment by “similarity” as compared with a previously Approved
Equipment.
Generally ,if a pizza box type equipment having the same size, weight, physical and electrical
properties as well as possessing the same material components to that of a equipment that
has been previously tested and passed for fire propagation characteristics, need not be tested
again.
A statement is required from an approved testing lab stating:
1) Equipment “A” contains same material as Equipment “B”
2) Equipment “A” has the same physical and electrical characteristics as equipment “B”
3) Equipment “A” has same fire propagation characteristics as Equipment “B”
Submit:
4) A test report with date and test results for Equipment “B”
5) Any exception taken during the test of Equipment “B”
