5ESS (Electronic Switching System) Manual #1








       Note:   The 235-XXX-XXX manuals do not provide maintenance

               procedures for the repair of equipment (for

               example, tape drives or disk drives) manufactured

               by vendors other than AT&T.  To identify the

               appropriate maintenance manual for each unit of

               such vendor equipment, refer to Section 3 of AT&T

               235-001-001, Documentation Description and Ordering

               Guide.  This guide only provides the vendor's

               address associated to the unit in question, not the

               procedures used to repair the faulty equipment.



     This document describes the maintenance concepts and built-in

     maintenance capabilities of the 5ESS(R) switch.  The information

     is necessary to perform system evaluation and maintenance.  To

     be adequately prepared to maintain the 5ESS switch, the

     following prerequisites are recommended for maintenance

     personnel:



       a. Must be familiar with telephone equipment and terminology.



       b. Must complete maintenance training on the 5ESS switch.



       c. Must be familiar with the information in the following

          manual(s):



            o  AT&T 235-100-125, System Description 5E6 and Later



            o  AT&T 235-900-106, Product Specification 5E6



            o  AT&T 235-900-107, Product Specification 5E7



            o  AT&T 235-900-108, Product Specification 5E8.



            o  AT&T 235-900-109, Product Specification 5E9(1).



            Note:   These manuals also contain a section

                    concerning Environmental Specifications

                    (physical specifications) that can be useful

                    to maintenance personnel.



     Product rating for the 5E2(2), 5E3, 5E4, and 5E5 software

     releases has been changed to Discontinued Availability (DA).

     Effective with Issue 7.00, all information on the DA rated

     software releases is being removed from this document.



     This document is updated to provide coverage for the 5E7 (Issue

     5.00), 5E8 (Issues 6.00 and 6.01), and 5E9(1) (Issue 7.00)

                 o  Office Dependent Data - Maintenance Procedures:

                    This section contains a series of task-oriented

                    corrective maintenance procedures that can be

                    used to maintain and repair office dependent data

                    (ODD) associated with the switch.



                 o  Supporting Information: This section contains a

                    tabular list that describes all the diagnostic

                    phase descriptions and a Basic Rate Interface

                    (BRI) trouble-shooting diagram.



               The AT&T 235-105-220 also has a group of job aids for

               the TLWS poke commands which must be ordered

               separately (see AT&T 235-001-001, Documentation

               Description and Ordering Guide).



                 Note:   Refer to Table .AW TA/ for a complete list of

                         the operation and maintenance procedures

                         included in AT&T 235-105-220.



          3.   AT&T 235-105-250, System Recovery: Contains the

               descriptive material and detailed procedures of the

               software and hardware recovery capabilities of the

               5ESS switch.  Both automatic and manual recovery

               capabilities are covered.  The following is a list

               identifying what is covered in this manual:



                 o  System Recovery Description: In the 5ESS switch,

                    system recovery uses the concept of a network of

                    independent processors to localize recovery

                    actions.  The major processors involved are the

                    administrative module (AM), communication module

                    processor (CMP) (added in the 5E6 software

                    release), and the individual SMs. When a fault

                    exists, fault recovery attempts to reconfigure

                    the system to provide full system service

                    (primarily by excluding the faulty unit).

                    Several levels of recovery are available, and the

                    system can automatically escalate to higher and

                    broader levels if initial attempts fail.  The

                    higher recovery levels often include processor

                    initializations.



                    This section describes the various recovery

                    levels (and their impact) when used in the

                    different processors.  The strategy of

                    reconfiguration and escalation to higher recovery

                    levels is also covered, as is the mapping between

                    manual commands and internal recovery levels.



                 o  System Recovery Procedures: The procedures

                    provided in this section are used to clear system

                    failures which prevent the 5ESS switch from

                    restoring itself automatically. Also, procedures

                    are provided for analyzing the AM and SM

                    initializations.



                      Note:   Refer to Table .AW TA/ for a complete list

                              of the operation and maintenance

                              procedures included in AT&T 235-

                              105-250.



          4.   AT&T 235-105-119, Maintenance Guide Utilizing OMS5:

               This document provides information related to

               utilization of the OMS5 program.  The OMS5 program

               summarizes the receive-only printer (ROP) output into

               a readable format.  This program provides the

               maintenance personnel with an easy way to analyze how

               the office is performing.  After analyzing the OMS5

               program summary, the maintenance personnel should use

               the Corrective and Routine Maintenance Manuals (listed

               previously) with this manual to correct faults that

               occur in the switch.



               The OMS5 program runs on the switching control center

               (SCC) minicomputer.  The tape that contains the OMS5

               program can be obtained via the order number AT&T

               235-105-120.  This maintenance guide and the OMS5

               program can only be used via the SCC.



     The producers of this manual are constantly striving to improve

     quality and usability.  Please use the enclosed user feedback

     form [REF. .RM 1.9/] for your comments and to advise us of any

     errors.  If the form is missing or your comments will not fit, you

     This manual is distributed by the AT&T Customer Information

     Center in Indianapolis, Indiana. Most operating telephone

     companies should place orders through their documentation

     coordinator. Some companies may allow customers to order

     directly from the Customer Information Center; however, the

     majority do not. Companies that use documentation coordinators

     to manage their orders receive a significant discount. If you do

     not know the name/number of the documentation coordinator for

     your company, you may call 1-800-432-6600 to obtain the name and

     telephone number.



     Customers not represented by a documentation coordinator and

     AT&T employees can order the documentation for the 5ESS switch

     directly from the AT&T Customer Information Center.  Proper

     billing information must be provided.  These orders may be

     mailed to:



                       AT&T Customer Information Center

                       Order Entry

                       2855 N. Franklin Road

                       Indianapolis, IN 46219



     Orders may also be called in on 1-800-432-6600 or faxed in on

     1-317-322-6484.

     Technical assistance for the 5ESS switch can be obtained by

     calling the Regional Technical Assistance Center (RTAC) at

     1-800-225-RTAC.  This telephone number is monitored 24

     hours a day, 7 days a week.  During regular business hours,

     your call will be answered by your local RTAC.  Outside of

     normal business hours, all calls will be answered at a

     centralized technical assistance center where service-affecting

     problems will be dispatched immediately to your local RTAC.

     All other problems will be referred to your local RTAC on the

     next regular business day.
