4.0 QUALITY MANAGEMENT SYSTEM
General
ADTRAN has established a documented Quality Management System (QMS) to ensure control and continuous
improvement of the QMS processes. The QMS is set forth in this manual and is detailed in the reference procedures.
Referenced procedures also define the Product Life Cycle Model for all ADTRAN products, customer communication,
documentation requirements, internal auditing, manufacturing procedures, supplier evaluation and control,
performance measurements and implementing corrective and preventive action. The ADTRAN Quality Plan provides
an overview of the system.
The QMS within ADTRAN applies to interactions between, Engineering, Operations, Purchasing, Quality,
Sales/Marketing (includes Technical Support) and Training. The interaction of processes required for the QMS are
identified in Attachment 3.
The management of each functional group in the QMS is responsible for ensuring that quality consideration is an
integral part of all processes. Assuring compliance to the QMS, implementing actions necessary to achieve planned
results and continual improvement is a management responsibility.
The Purchasing organization is responsible for identifying and controlling all outsourced processes. Purchasing
ensures that these processes are identified within the QMS.

Document Q101, Revision W (Printout Uncontrolled) Page 8 of 23
contracts to assure the capability and desire to meet the requirements. Any exceptions are communicated through Sales
and Marketing, and negotiated to resolve or obtain the most favorable terms prior to contract execution; however, the
CEO or appropriate Division General Manager is authorized to finalize contract negotiations with unresolved issues if
an impasse occurs that could jeopardize the pending business relationship. Records of each contract review are
maintained by the appropriate organization. A copy of the executed contract is distributed to the cognizant departments
for reference in performing the contract. (GEN03.1, SL15)
The Sales and Marketing department communicates with our customers on product information, contracts, order
handling, amendments, customer feedback, including customer complaints. Sales and Marketing maintains a
documented customer notification process to ensure that customers are notified of any product problems or changes
that may affect them. The ADTRAN/Customer Purchase Contract and/or the latest issued Telcordia technical
publication GR-209-CORE are used as a guide for determining whether a product change warrants a customer
notification. (SL02)
Product repairs are coordinated by the Customer and Product Service group (CaPS). The warranty period and any
special handling requirements are outlined in the repair warranty agreement or customer contract. (GEN02.3)
ADTRAN maintains a dedicated Technical Service function whose responsibilities include: providing answers to
technical and application questions, assisting in resolution of problems, and Marketing for product training. Product
training is available for ADTRAN personnel and customers.

The results of an engineering product design are evidenced in successive releases, i.e., Engineering Prototype,
Production Planning, Limited Production and Full Production. A comprehensive checklist of required items to
accomplish each release includes attention to Bill of Material entries, Piece Part Drawings, PCB Artwork, Test Set and
Documentation, Design Verification Testing, Acceptance Test Procedure etc. The entire set of ADTRAN policies and
procedures is intended to influence the quality of designs, reduce the length and cost of the development cycle, and to
meet the requirements of our customers. (GEN04.4, GEN05.5, EN02, EN10, and EN11)
Software outputs include specifications, source code, executable files, and user documentation.
Design Review
Processes for conducting design reviews have been established to ensure that, at appropriate stages of design, it is
reviewed to assure that planned activities have been conducted. Participants involved are those required for the specific
stage of design and determined by the responsible engineer. Engineering holds design reviews and maintains records
of these reviews. (GEN09.3, EN02, PQ01)
Design reviews and design verification tests are conducted by Design Engineering during the development of a
product. The culmination of the design phase results in a formal documentation release meeting to facilitate first
production. (EN10 and GEN05.5)

Document Q101, Revision W (Printout Uncontrolled) Page 10 of 23
Verification
The responsible engineer develops a Design Verification Test (DVT) to ensure that the design meets the intended
requirements. The results of these tests are recorded and maintained by Document Control. (EN10)
During product qualification testing, user documentation is verified; stress testing, system testing and abnormal
conditions tests are performed. (PQ01)
Validation
In addition to design verification tests, Product Qualification/Validation is performed in accordance with planned
arrangements by the Product Qualification group, which tests the product in a user intended environment. The Product
Qualification department maintains records of the results of these tests. (PQ01)
Release Management
Product Management and Marketing review the product schedules and status. This information is communicated to
the customer in advance. This information aids the customer in planning for upcoming product hardware and software
releases. (EN06, SL02, GEN21.2)
Changes
Any changes to released documentation require approval of the Responsible Engineer, Responsible Manager,
Configuration Control, and the Quality Assurance department, as a minimum. Design Engineering ensures that fixes to
problems are incorporated into future designs. Approval by other departments is on an as-needed basis when affected
by the Engineering Change Order (ECO). Records of the results and review of changes are maintained by the
Document Control department. (GEN05.4)

contractual commitments. (EN06, GEN05.4 and SL02)
Component Engineering evaluates, per procedures, all component changes and substitutions to ensure quality product
performance. (GEN0401, PG13)
Purchasing
The quality of finished products and ultimately the customer’s satisfaction depends on procured materials and
subassemblies. Effective supplier selection, procurement, measurement, disposition of discrepant materials, supplier
rating reports, and joint ADTRAN/supplier participation are essential to providing high quality products. Documented
Purchasing procedures are in place to facilitate these activities. (GEN06.1, GEN06.2, GEN06.8, GEN06.11, PG13)
ADTRAN suppliers are evaluated, per documented procedures, by Purchasing, Component Engineering, and Supplier
Quality. Records of these reviews are maintained. (GEN06.11)
Purchase Orders (Pos) are placed using ADTRAN assigned released part numbers that are unique to the specific part.
Purchase Orders include the applicable Quality System to be applied and all contract requirements. The supplier has
the responsibility for ensuring that purchased products meet ADTRAN specifications for quality. (PG13)
All purchased material is confirmed to meet required specifications. This confirmation is by use of sampling plans
either at ADTRAN Component Inspection, Quality Assurance or by ADTRAN Source Inspection. A Dock-To-Stock
program is in place expediting material from suppliers that consistently meets ADTRAN requirements. Purchasing
documents define verification arrangements and the method of product release when product acceptance is determined
to be at the supplier’s facility.
Production and Service Provision
Control of production and service provision
ADTRAN controls the process with documented requirements and audits of the processes. Each work order and each
purchase order for subcontractors specify process requirements. A Bill of Material (BOM) is generated for each work
order. On the Bill of Material, special assembly instructions relating to specific components are written. One item on
the Bill of Material is a drawing specifying the process flow. These drawings are released and controlled by

Document Q101, Revision W (Printout Uncontrolled) Page 11 of 23
Engineering Change Order (ECO). Any deviation to this process requires an approved Process Deviation Notice.
(AM4-9-1, EN05, GEN09.1, GEN09.2, GEN09.8)
Manufacturing processes are monitored utilizing suitable process parameters and product characteristics. Operators
and inspectors record the results of inspections and tests for analysis. (AM4.20-1, AM4.9-1, AM4.10-2, QA10.15)

detection and removal from the software deliverable. (EN06, EN11)
Validation of Processes
Manufacturing processes are monitored utilizing suitable process parameters and product characteristics. Operators
and inspectors record the results of inspections and tests for analysis.
Criteria for operator qualification(s) have been established and documented, along with an employee skill list that is
utilized in determining work assignments.
Each time a significant change to a production process is made, Process Engineering ensures a critical examination of
the first unit(s) is performed.
Identification and Traceability
ADTRAN controls and documents the configuration of all its products utilizing a defined process. Product
development and changes are recorded and controlled to assure defined requirements are completed prior to further
processing. (GEN08.1)
Each assembly, subassembly, and component is assigned a unique number. Engineering creates Bills of Materials
and/or drawings for all assemblies and subassemblies. Printed circuit boards are identified with ADTRAN part
numbers. In addition, serial numbers are assigned to each unit in a work order. Serial number labels are attached

Document Q101, Revision W (Printout Uncontrolled) Page 12 of 23
during the manufacturing process. Traceability is then maintained within ADTRAN’s Management Information
System by part number for data collection purposes, trace design changes, and for product recalls.
Customer Property
Each customer-supplied product is assigned a unique ADTRAN part number. Definition of the supplied product is also
required so that Component Inspection can confirm the product meets specified requirements. The unique ADTRAN
part number allows for separation in storage and maintenance, if required. Procedures are in place to ensure that Sales
and Marketing notify the customers of product issues. (GEN07.1)
Preservation of Product
Material handling includes methods and equipment required to move or store purchased, in-process, manufactured, or
completed material. Adequate handling methods and procedures are proposed and used to prevent damage, loss,
deterioration or degradation of the product. These procedures may include the use of special boxes, containers, and
Electrostatic Discharge (ESD) controls. Manufacturing Engineering is responsible for preparing and implementing
handling procedures with Quality Engineering approval. (GEN15.1)
ADTRAN documentation defines the steps to be taken for proper handling of ESD sensitive material and assemblies,
both within ADTRAN and when transported to and from our subcontractors. (GEN09.5)

packaging quality. (QA10.5)
The Materials manager has the responsibility for technical direction of material storage to minimize the possibility of
damage, corrosion, deterioration, or contamination.
Handling and storage practices are defined in ADTRAN’s Stockroom procedure(s). A first-In, First-out (FIFO)
inventory control system is used. Items with definitive shelf life are stipulated and controlled. (GEN09.5, GEN15.1)
Control of Monitoring and Measuring Equipment
ADTRAN uses an outside service to perform equipment calibration a minimum of two times a year. Each service
results in calibration of a portion of the equipment requiring calibration. Primarily, each piece of equipment will be
calibrated once each year. The frequency may be changed for specific equipment based on history.
The Corporate Quality department maintains a listing of all equipment requiring calibration. The listing is reviewed by
Quality on a regular basis. In addition, process audits require confirmation of calibration status of equipment. All
inspection, measuring, and test equipment that do not require calibration are identified as such. (GEN11.1, GEN11.6)
8.0 MEASUREMENT, ANALYSIS AND IMPROVEMENT
General
Statistical techniques and team tools are used throughout ADTRAN processes to assure process controls and
continuous improvement, as well as verification of results. This data is reviewed regularly to determine appropriate
changes required to cause consistent improvement.

Quality Audit performs regularly scheduled internal audits to assure compliance with established processes. These
audits are conducted by trained personnel who coordinate the audits with area managers. The results of the audits are
documented; corrective actions are documented and evaluated through follow-up audits. These audit reports are
forwarded to management for review. (GEN17.1)
Processes
Corporate Quality Plans are developed to identify suitable methods of monitoring and measuring QMS processes.
Corrective action is taken when unfavorable conditions exist. (GEN01.1)
Operations Quality consistently monitors the production process, at appropriate points, through statistical process
control methods. Corrective actions and preventive actions are implemented when necessary. (AM20-1)
Product
ADTRAN has implemented inspection and test points to ensure product requirements are met. Inspectors and Test
Operators work from detailed work instructions. Records are maintained on all inspection and testing activities.
ADTRAN performs functional and final testing to engineering released Acceptance Test Procedures (ATP). The
continuous flow lines at ADTRAN utilize the concepts of all personnel as inspectors to visually detect workmanship
defects prior to packaging.
Inspection and test records are recorded by the performing function and maintained electronically on the ADTRAN
internal network. Records include, but are not limited to: product identification, quantity of product inspected,
inspection procedures followed, person performing the test and inspection, date of inspection and/or test, number, type,
and severity of defects found.
Product requalification / retesting of released product is accomplished by Quality Assurance / Operations on a periodic
basis. “Retesting” is conducted in a more robust environment than the original acceptance test. ( GEN10.3 and RE01)
All ADTRAN returned products are reworked, or repaired, and retested in accordance with the ADTRAN Engineering
Acceptance Test Procedures.
Software tests are conducted according to documented procedures and test plans. (EN10, PQ01)
Control of Non-conforming Product
Non-conforming material is reviewed and dispositioned by the Material Review Board (MRB). The chairperson of this
board is the Quality representative. Operations Engineering, Manufacturing Services, and Purchasing are also board
members. Other support personnel may be called upon as required. MRB dispositions are use-as-Is, Scrap, Repair, or
Return to Vendor. Standard rework that meets specification requires no disposition. All rework or repair is subjected to
inspection prior to continuing processing. Records of discrepancies are maintained on the ADTRAN internal network
and reviewed for trends as input for corrective and preventive action. (GEN13.1,GEN13.2 GEN13.3 and AM4.13-1)
Analysis of Data
Data and information recorded in quality records are compiled and analyzed periodically to determine trends in the
performance and effectiveness of the quality system and to identify opportunities for improvement Some data utilized
in this process comes from, but is not limited to, the following:
Customer Satisfaction Surveys Field Performance Data Internal Audit Results
Inspection Records Corrective and Preventive Action Nonconforming Material
Manufacturing and Test Records First Pass Yield and Delivery Supplier Performance
Corporate Quality is responsible for coordinating these activities, and for reporting conclusions and trends to top
management. This is usually done within the framework of management reports and reviews of the quality system.

Improvement
Continual Improvement
ADTRAN’s Quality Improvement Program has, as its nucleus, the Continuous Improvement Team (CIT) concept.
Teams provide the forum by which all employees can contribute to quality improvements proactively. Teams identify
and prioritize improvement activities. The results of the team efforts are periodically presented to upper management.
ADTRAN maintains a documented Quality Improvement and Customer Satisfaction program to promote continuous
improvement of customer satisfaction, products, services, and processes within ADTRAN. (GEN21.1)
Corrective Action
The ADTRAN corrective action procedure defines the means by which anyone with a problem can cause action to
occur for resolution of a problem. The problem may be related to product or process. The originator defines the
problem and assigns the individual responsible for resolution. Corrective Action Requests are documented in the
ADTRAN corrective action system(s), and maintained for a minimum of one year. The originator is responsible for
verifying action effectiveness and the quality organization periodically audits for the same. (GEN14.1)
All forms of customer complaints are captured and maintained within the ADTRAN corrective action process to assure
effective actions are taken and responses provided. (GEN14.1)
Preventive Action
Management reviews product and process data identifying potential problems, their causes and determining the action
required to eliminate the possibility of occurrence. Preventative actions are documented utilizing ADTRAN’s
documented corrective action system and/or action item registers.
All ADTRAN associates are encouraged to analyze the need for preventative action when implementing or changing
actions or functions. (GEN14.1)
