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

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

Since this document has been developed to describe maintenance
concepts and maintenance capabilities for the 5ESS switch, it is
appropriate to identify the manuals that contain the procedures
used to maintain the switch.
1. AT&T 235-105-210, Routine Operations and Maintenance
Procedures: Contains the descriptive material and
detailed procedures for routine operations and
maintenance of the 5ESS switch. The following is a
list of the sections in this document:
o Equipment Test List (ETL)
o Operations (system control functions)
o Memory Alteration Description
o Memory Alteration Procedures
o Abnormal Input Message Acknowledgments
o Fan and Alarm Tests
o Moving Head Disk (MHD) Procedures
o Miscellaneous Routine Procedures
o ROTL
o Routine Exercise Procedures.
The AT&T 235-105-210 also has a job aid for O&M
Checklist 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 235-105-210.
2. AT&T 235-105-220, Corrective Maintenance Procedures:
Contains three sections as follows:
o Hardware - Maintenance Procedures: This section
contains a series of task-oriented corrective
maintenance procedures that can be used by
personnel who are involved in maintaining various
hardware units and circuits of the 5ESS switch.
Also, some procedures are used to resolve
subscribing customer service complaints.
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.

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

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
