with your telecommunications s ys tem and, if toll f r a ud occurs, it can
result in substantial additional charges for your telecommunications
services.

You and your sys tem manager are respons ible for the security of your
system, such as programming and configuring yo ur equipment to pr e­vent unauthorized use. The system manager is also respo nsible for
reading all installation, instruction, and system administration docu­ments provid ed w ith this product in order to fully understand the fea­tures that can introdu ce risk of toll fraud and the step s that can be t aken
to reduce that risk. Lu cent Te chn ol ogie s does not w a rrant that this
product is immune from or will pre vent unauthorized use of com­mon-carrier telecommunication services or facilities accessed th r ough

Federal Communications Commission Statement
Part 15: Class A Statement. This equi pment has been tested and

found to comply with the limit s for a Class A digita l dev ic e, pur suan t
to Part 15 of the FCC Rules. These limits are designed to provide rea­sonable prot ection against harmful interference when the equipment is
operated in a commer cial environm ent. This equipment generates,
uses, and can radiate radio-frequency energy and, if not installed and
used in accorda nce with the ins tru ctio ns, may caus e har mful in terfe r­ence to radio communications. Operation of this equipment in a resi­dential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at his own expense.

Part 68: Network Registration Number. This equipment is registered
with the FCC in accordance with Part 68 of the FCC Rules. It is identi­fied by FCC registration number AS593M-13283-MF-E.

Part 68: Answer-Supervision Signaling. Allowing this equipment to
be operated in a manner that does not provide prope r ans w er-supervi­sion signaling is in violation of Part 68 Rules. This equipment returns
answer-supervision signals to the public switched network when:

• Answered by the called station

• Answered by the attendant

• Routed to a recorded announcement that can be administer ed by
the CPE user

This equipmen t returns answer- s upervision signals on all DID calls
forwarded back t o the public swit ched telephone network. Permis s ible
exceptions ar e:

• A call is unanswered

• A busy tone is received

• A reorder tone is received

This book has the information needed to monitor, test, and maintain DEFINITY

®

Enterprise Communications Server Release 5 Systems and covers many of the
faults and troubles that can occur in the system. Most maintenance requirements
are simple procedures due to the modular, self-testing nature of the system.

This document covers information related to DEFINITY ECS Release 5, and
includes all incremental releases up to and including Release 5.4. For details
about changes for Release 5.4, refer to

Server Release 5.4.0, Change Description

DEFINITY Enterprise Communications

, 555-230-471.

Simple, traditional troubleshooting methods are sometime s sufficient to locate
and clear faults. The traditional methods include terminal substitution, visual
inspections, continuity checks, and clarification of operating procedures with
users.

The information in this book is intended for use by:

■ A maintenance technician dispatched to a DEFINITY System site in

response to a trouble alarm or a user trouble report,

■ A maintenance technician located at a remote maintenance facility, or

■ The user’s assigned maintenance technician. The technician is expected

to have a knowledge of telecommunications fundamentals and of the
DEFINITY

Maintenance Architecture

The maintenance subsystem is a part of the software that initializes and
maintains the system. The software continuously monitors system health, and
keeps a record of errors detected in the system. The maintenance subsystem
also provides a user interface for on-demand testing.

555-230-123

Issue 1

April 199 7

Page 1-1Maintenan ce O bjects

This chapter provides a brief description of the Release 5 maintenance strategy
and the bac kground information on the system’s overall functions. For detailed

descriptions of components and subsystems, refer to related topics in Chapter

10, ‘‘Maintenance Object Repair Procedures’’.

Maintenance Objects

The system is partitioned into separate entities called Maintenance Objects
(MOs). Each MO is referred to by an upper-case, mnemonic-like name that
serves as an abbreviation for the MO. For example, “CO-TRK” stands for “Central
Office TRunK”. Each MO is monitored by the system and has its own
maintenance strategy. Most MOs are individual circuit packs. Som e MOs are
hardware components that reside on part of a circuit pack. For example, the
TDM bus Clock circuits reside on the Tone/Clock circuit pack. Other MOs, such
as cabinet environmental sensors, represent larger subsystems or sets of
monitors. Finally, some MOs, such as SYNChronization, represent processes or a
combination of processes and hardware.

“Maintenance names” are recorded in the error and alarm logs. Individual copies
of an MO are assigned an address that defines the MO’s physical location in the
system. These locations disp lay a s the “PORT” fiel d in the alarm and err or lo gs
and as output of various commands such as test board, busy tdm-bus, and so
forth.

555-230-123

Alarm and Error Reporting

During normal operations, software or firmware may detect error conditions
relevant to specific MOs. The system attempts to fix or circumvent these
problems automatically. However, if a hardware component incurs too many
errors, an alarm is raised. Errors are detected in two ways:

■ For “in-line” errors, firmware on the component detects the

occurrence of an error during ongoing operations.

■ For other types of errors, a “periodic test” or a “scheduled test”

started by the software detects the error. The technician can run
these tests on demand by using the maintenance comman ds
described in Chapter 8, ‘‘

‘‘Maintenance Object Repair Proced ures ’’.

Software puts the error in the error log, and increments the error counter for that
error. When an error counter is “active,” (greater than zero), there is a
maintenance record for the MO.

busyout journal-printer’’, and Chapter 10,

Issue 1

April 199 7

Page 1-2Alarm and Error Reporting

Alarms are classified as MAJOR, MINOR, or WARNING, depending on the effect
on system operation. They are also classified as ON-BOARD or OFF-BOA R D.

— MAJOR alarms identify failures that cause a critical degradation of

service. These alarms require immediate attention.

— MINOR alarms identify failures that cause some service degradation but

that do not render a crucial portion of the system inoperable. MINOR
alarms require attention. However, typically a MINOR alarm affects only a
few trunks or stations or a single feature.

— WARNING alarms identify failures that cause no significant degradation of

service or equipment failures external to the switch. These failures are not
reported to INADS or to the attendant console.

— ON-BOARD problems originate in the circuitry on the alarmed circuit

pack.

— OFF-BOARD problems originate in a process or component that is

external to the circuit pack.

Alarms are discussed further in Chapter 10, ‘‘

Procedures’’.

Maintenance Testing

Maintenance Ob ject Repair

Most troubles are reduced to the circuit pack level and can be identified by LEDs
on the circuit packs and software reports generated by the system. The
maintenance tests in the system are divided into three groups:

■ Periodic

DEFINITY Enterprise Com munications Server Release 5
Maintenance and Test for R5vs/si

Maintenance Architecture

555-230-123

Background tests are performed by software maintenance, usually on an
hourly basis. These tests are nondestructive and can be run during high
traffic periods without interfering with calls.

■ Scheduled

Background tests performed by software maintenanc e, usually on a daily
basis, are generally more thorough than periodic testing. The tests are
considered destructive and are run only during off-hours so as not to
interfere with calls.

■ Fixed interval

Background tests performed by software maintenance at regular time
intervals (these intervals cannot be administered). These tests run
concurrently with periodic maintenance. The following table lists the MOs
that run fixed interval testing.

Maintenance Object

April 199 7

Page 1-3Protocols

Interval

(minutes)

Demand tests are also run by the system when it detects a need or by
maintenance personnel in trouble-clearing activities. Demand tests include
periodic tests plus other tests required only when trouble occurs. Some
nonperiodic demand tests may disrupt system operation. In this book,
destructive (service-disrupting) tests are identified in boldface type.

Maintenance personnel can use the management terminal to initiate the same
tests that the system initiates. The terminal screen displays the test results.

Protocols

these protocols change. Figure 1-1

that contain call-signaling and caller information. These elements conform to
ISDN level-3 protocol. In the case of BRI, the elements are created by the
terminal or data module; for the PRI, the elements are created by the system,
which inserts them into the D-channel at the DS1 port.

For ISDN transmissions, therefore, BRI terminals and data modules, and DS1
ports insert, interpret, and strip both layer-2 DCE information and layer-3
elements. Also, the DS1 port passes layer-3 elements to the system for
processing.

Layers

The Open System Interconnect (OSI) model for data communi cations cont ains
seven layers, each with a specific function. Communications to and through the
system concern themselves only with layers 1 and 2 of the model.

Issue 1

April 199 7

Page 1-4Protocols

Layer 1, or the

physical layer,

covers the physical interface between devices and
the rules by which bits are passed. Among the physical layer protocols are
RS-232, RS-449, X.21, DCP, DS1, and others.

Layer 2, or the

data-link layer

, refers to code created and interpreted by the DCE.
The originating equipment can send blocks of data with the necessary codes for
synchronization, error control, or flow control. With these codes, the destination
equipment checks the physical-link reliability, corrects any transmission errors,
and maintains the link. When a transmission reaches the destination equipment,
it strips any layer-2 information the originating equipment may have inserted. The
destination equipment only passes to the destination DTE equipment the
information sent by the originating DTE equipment. The originating DTE
equipment can also add layer-2 code to be analyzed by the destination DTE
equipment. The DCE equipment treats this layer as data and passes it along to
the destination DTE equipment as it would any other binary bits.

Layers 3 to 7 (and the DTE-created layer 2) are embedded in the transmission
stream and are meaningful only at the destination DTE equipment. Therefore,

they are shown in the figure as ‘‘user-defined,’’ with no state changes until the
transmission stream reaches its destination.

Usage

The following is a list of the protocols when data is t ransmitted to and through the
system. The list is organized by proto c ol layers. Refer to Figure 1-1

Layer-1 Protocols

Layer-1 protocols are used between the terminal or host DTE and the DCE, used
between the DCE equipment and the system port, and used inside the system.

The following layer-1 protocols are used between the DTE equipment and the
DCE equipment. DCE equipment can be data modules, modems, or Data
Service Units (DSUs). A DSU is a device that transmits digital data to a particular
digital endpoint over the public network without processing the data through any
intervening private network switches.

V.35

— A physical interface used to connect DTE to a DCE. This protocol

is typically used for transmissions at 56 or 64 kbps

The following protocols are used at layer 1 to govern communication between the
DCE equipment and the port. These protocols consist of codes inserted at the
originating DCE and stripped at the port. The DS1 protocol can be inserted at the
originating, outgoing trunk port and stripped at the destination port.

■

Digital Communications Protocol (DCP)

— A standard for a 3-channel

link. This protocol sends digitized voice and digital data in frames at 160
kbps. The channel structure consists of two information (I) channels and
one signaling (S) channel. Each I-channel provides 64 kbps of voice
and/or data communication and the S-channel provi des 8 kbps of
signaling communication between the system and DTE equipment. DCP is
similar to ISDN-BRI

■

Basic Rate Interface (BRI)

— An ISDN standard for a 3-channel link,

consisting of two 64-kbps bearer (B) channels and one 16-kbps signaling
(D) channel. For the implementation of this standard, see

Connectivity Rules

Figure 1-1 implies the following connectivity rules:

Issue 1

April 199 7

Page 1-9Protocols

■ Only the DS1 port and the analog trunk port are trunking facilities (all other

ports are line ports). For communication over these facilities, the
destination DCE equipment can be a hemisphere away from the system,
and the signal can traverse any number of intervening switching systems
before reaching the destination equipment.

■ Data originating at any type of digital device, whether DCP or BRI, can exit

the system at any type of digital port — BRI, digital-line, PRI, DS1, and
others; as long as the call destination is equipped with a data module
using the same DMI mode used at the call origin. This is because once the
data enters the system through a digital port, its representation is uniform
(raw bits at layer 1, and DMI at level 2), regardless of where it originated.

■ Although data entering the system through an EIA port has not been

processed through a data module, the port itself has a built-in data
module. In side th e system , p o r t data is i denti c a l to d igital li ne data. Dat a
entering the system at a DCP line port can exit at an EIA port. Conversely,
data entering the system at an EIA port can exit at any DCP line port. The
destination data module must be set for Mode-2 DMI communication.

■ Voice-grade data can be carried over a DS1 facility as long as the

destination equipment is a modem compatible with the originating modem

■ If a mismatch exists between the types of signals used by the endpoints in

a connection (for example, the equipment at one end is an analog
modem, and the equipment at the other end is a digital data module), a
modem-pool member must be inserted in the circuit. When the endpoints
are on different switches, it is recommended that the modem-pool
member be put on the origination or destination system. A modem-pool

DEFINITY Enterprise Com munications Server Release 5
Maintenance and Test for R5vs/si

Maintenance Architecture

555-230-123

member is always inserted automatically for calls to off-premises sites via
analog or voice-grade trunking. For internal calls, however, the systems
are capable of automatically inserting a modem-pool member.

■ Data cannot be carried over analog facilities unless inside the system it is

represented as a Pulse Code Modulation (PCM)-encoded analog signal.
To do this for data originating at a digital terminal, the signal enters the
system at a digital port and exits the system at a digital port. The signal
then reenters the system through a modem-pool connection (data-module
to modem to analog-port) and exit s the syste m again at an analo g port .

■ Although DS1 is commonly called a trunk speed, here it names the

protocol used at layer 1 for digital trunks. Some trunks use different
signaling methods but use DS1 protocol at layer 1 (for example, PRI and
24th-channel signaling trunks).

Disconnect Supervision

Disconnect supervision means the CO has the ability to release a trunk when the
party at the CO disconnects, and the system is able to recognize the release
signal. In general, a CO in the United States provides disconnect supervision for
incoming calls but not for outgoing calls. Many other countries do not provide
disconnect supervision on either incoming or outgoing calls.

Issue 1

April 199 7

Page 1-10Protocols

The system must provide the assurance that at least one party on the call can
control the dropping of the call. This avoids locking up circuits on a call where no
party is able to send a disconnect signal to the system. Internal operations must
check to be sure one party can provide disconnect supervision. An incoming
trunk that does not provide disconnect supervision is not allowed to terminate to
an outgoing trunk that does not provide disconnect supervision.

In a DCS environment, an incoming trunk without disconnect supervision can
terminate to an outgoing DCS trunk connecting two nodes. The incoming trunk is
restricted from being transferred to a party without disconnect supervision on the
terminating node.

This is because, through messaging, the terminating node knows the originating
node cannot provide disconnect supervision. This messaging is not possible with
non-DCS tie trunks, and the direct call is denied.

Some two-wire loop start trunks outside the United States provide busy tone
disconnect in place of line signals. For these trunks, an adjunct can be attached
to the trunk to listen for busy or other disconnect tone. When a tone is detected,
the adjunct sends line signals for disconnect to the system.

Administration is provided for each trunk group to indicate whether it provides
disconnect supervision for incoming calls and for outgoing calls.

Transfer on Ringing

A station or attendant may conference in a ringing station or transfer a party to a
ringing station. When a station conferences in a ringing station and then drops
the call, the ringing station is treated like a party without disconnect supervision.
However, when a station transfers a party to a ringing station, the ringing station
party is treated like a party with disconnect supervision. Two timers (Attendant
Return Call Timer and Wait Answer Supervision Timer) are provided to ensure the
call is not locked to a ringing station.

Conference, Transfer, and Call-Forwar ding Denial

If a station or attendant attempts to connect parties without disconnect
supervision together, the following is possible:

■

Digital Station or Local Attendant Transfer

transfer the two parties together, the call appearance lamp flutters,
indicating a denial. If transferring to a DCS trunk, the denial may drop the
call since the transfer is allowed and the other system is queried for
disconnect supervision.

Power

There are two basic powering options available with the Release 5si systems.
These options include AC and DC. The cabinets and their associated power
supplies can be powered by 120/208 volts AC either directly or from a Universal
Power Supply (UPS) system. Alternatively, the cabinets and their power supplies
may be powered by -48 volts DC from a battery power plant.

The Release 5vs system requires between 80 and 264 or between 90 and 132
volts AC. The system can be powered directly or from the WP-90510 power
supply. The DC power option is not available with this system.

Except for the Release 5vs system, each control cabinet in an AC-powered
system has an internal batte ry th a t provides a short term holdover to protect th e
system against short power interruptions. This method is known as the Nominal
Power Holdover Strategy. The battery is connected so that it automatically
provides power if the AC service fails. The time and extent of the holdover varies
according to the type of cabinet and to whether or not the system has a
duplicated control complex.

NOTE:

When EPN power is interrupted for greater than the cabinet holdover but
less than the control carrier holdover, calls in the control carrier are held for
the duration of the interruption but are dropped when power is restored.

Single-Carrier Cabinets

In single-carrier cabinets, there is no internal AC wiring or distribution and no
software interacti o n with th e powe r system. The power supplies themselves take
about 250 milliseconds for the voltages to drop below limits.

The control cabinet that houses the Switch Processing Element (SPE) is the only
cabinet that has an internal battery reserve. All other control cabinets and port
cabinets have the 250 millisecond power supply deca y de lay , after which all
connections and links associated with the cabinets are dropped.

DEFINITY Enterprise Com munications Server Release 5
Maintenance and Test for R5vs/si

Circuit Packs and Power

555-230-123

The SPE control cabinet has a battery that furnishes power to the processor
memory complex for a minimum of two minutes if the battery is fully charged. This
battery is recharged after power is restored, but the charging process is not
monitored by the system. The cabinet is not able to detect AC power loss, and it
notices only a DC power output failure as the power supply output decays.

The memory contents are preserved, and the processor continue s operating
during the two minute period. However, the tone-clock circuit pack is not held
over, and as a result, no connections are possible. The battery does not supply
all the voltages necessary for the internal modem circuit on the processor circuit
pack. As a result, no call is originated to INADS, and the switch cannot answer
any calls. Thus, the switch cannot report any internal or external alarms during
this period. After two minutes (depending on the condition of the battery), the
processor and memory are lost, and the system is totally inactive.

If power is restored in less than 250 milliseconds, no calls are dropped. If power
is restored between 250 milliseconds and two minutes, all calls are dropped, and
memory is maintained. However, since the tone-clock was lost, the system
undergoes a reset once the AC restoral process clears all calls and the alarm log
(in which errors are retained). The switch keeps a record of the restart in the error
log, but it might not detect a power error if the outage is between 1/4 of a second
and one minute, during which time only a loss of clock and not a loss of the
power failure that caused the loss of clock is logged. After one minute, a power
error is logged. If the outage exceeds the battery holdover interval, the error logs
and alarm logs are lost (since they cannot be saved to tape). Depending on the
size of the system, it can take up to one minute to restore service to the ports.
After a power outage of two minutes following the restoral of AC power, the
system re-initializes from the tape. It takes about 10 minutes to restore service.
Again, if the customer has frequent power outages or critical service needs, an
external UPS or DC power system should be considered.

connects to the Duplication Interface circuit pack in the PPN. In the EPN of a
standard reliabili ty system or of a high or critical reliability system, the
administration terminal connects to the Maintenance circuit pack in the EPN.

Duplication Interface circuit pack A controls and monitors the same environment
leads as the Maintenance/Tape Processor in a PPN system without high or
critical reliability. Duplication Interface circuit pack A also supports the serial
channel to the terminal in a PPN for a high or critical reliability system. The

System Login Procedure

Forced Password Aging and Administrable Logins

Release 5 and later releases provide enhanced login/passw ord security by
adding a security feature that allows users to define their own logins/passwords
and to specify a set of commands for each login. The system allows up to 11
customer logins. Each login name can be customized and m ust be made up of
from 3 to 6 alphabetic/numeric characters, or a combination of both. A password
must be from 4 to 11 characters in length and contain at least 1 alphabetic and 1
numeric symbol. Password aging is an optional feature that the super-user
administering the logins can activate.

NOTE:

If several users are logging in and out at the same time, a user may see the

message “Transient command conflict detected; please try later”. After the
“users” have completed logging in or out, the terminal is available for use.

Issue 1

April 199 7

Page 3-3System Login Procedure

The password for each login can be aged starting with the date the password
was created, or changed, and continuing for a specified number of days (1 to

99). The user is notified at the login prompt, 7 days before the password
expiration date, that the password is about to expire. When the password expires
the user is required to enter a new password into the system before logging in. If
a login is added or removed, the “Security Measurement” reports are not
updated until the next hourly poll, or a clear measurements security-violations
command is entered. Once a non-super-user has changed the password, the
user must wait 24 hours to change the password again.

Security is enhanced by providing a logoff notification screen to a system
administrator at log off while either the facilit y test call or remote access features
are still administered. The administrator can be required to acknowledge the
notification before completing the logoff process. Logoff notification is
administered on the Login Administration screen.

Release 5 and later releases are delivered to the customer with one customer
“super-user” login/password defined. The customer is required to administer
additional login/passwords as needed. The super-user login has full customer
permissions and can customize any login created.

Login permissions for a specified login can be set by the super-user to block any
object that may compromise switch security. Up to 40 administration or
maintenance objects commands can be blocked for a specified login in.

Release 5 and later releases commands are grouped into three comma nd
categories. Each of the three command categories has a group of command
subcategories listed under them, and each command subcategory has a list of
command objects that the commands acts on. A super-user can set a users

Administering Login Command Permissions

Users with super-user permissions can set the permissions of the logins they
create. The Command Permissions Categories form displays fields to which a
user with super-user permissions can give or limit access. These commands are
divided into three categories:

■ Common Command

■ Administration Commands

■ Optional Maintenance Command s

Each of the three main categories have subcategories listed under them that

when set to a “y” give permission to use the command sets associated with that
category. When the Command Permissions Categories form is displayed for a
login, the subcategories fields appear with the fields set to give the login full
permissions for that login type. The super-user administering login permissions
can set any of these field to deny access to a command category for the
specified login. If the super-user making the assignments has full super-user
permissions and would like to limit permissions for a category, the super-user
can do so by entering “y” in the Additional Restrictions field located under the
Administration Category section of the Command Permissions Categories form.

Issue 1

Refer to the Command Permissions Form Entries Tables at the end of t hi s s ection
for a list of command Objects and Actions by:

■ Display Administration and Maintenance

■ Administer Features

■ Administer Permissions

■ Administer Stations

■ Administer Trunks

The information is the tables will help you to establish command permissions for
user logins.

To administer command permissions, log in as super-user and:

1. Access the Command Permissions Categories form by entering change
permiss io ns l ogi n [ lo gi n name]. When the form is displayed for a login,
the default permissions for that “login type” are shown. The super-user
administering the login can change a “y” to “n” for each subcategory field.

2. Select a category for the login and enter “y” in each field where
permission to perform an administrative or maintenance action is needed.
The command object you select must be within the permissions for the
login type you are administering.

If the Maintenance option is set to “y” on the Customer Options form, the
super-user can enter “y” in the Maintain Switch Circuit Packs? or Maintain
Process Circuit Packs fields.

Switch-Based Bulletin Board

This feature will allow a user to leave messages in the system in order to
communicate with other system users.

NOTE:

This feature is not intended as a substitute for the existing procedures for
escalating problems, but only as an aid to the existing process.

Descrip tion

The bulletin board service provides an easy interface for the customer and
Lucent Technologies to leave messages on the system .

The bulletin board feature makes it easy for the customer to communicate with
Lucent Technologies (and vise-versa). For example, when a new load is installed
on a switch in the customer’s system, Lucent Technologies can leave the
customer messages which describe new functionality. This feature also allows
Lucent Technologies to keep the customer informed on the progress of trouble
items. In addition, the feature can be used by the customer to provide additional
information concerning problems that have already been escal ated.

Issue 1

April 199 7

Page 3-25Switch-Based Bulletin Board

Accessing the Bulletin Board

Any user with the appropriate permissions can log into the system and have

access to the bulletin board. User’s who have “Maintain System” or “Administer
Features” permissions can enter, change, display, print, or schedule to print a
message. Users who have “Display Admen” and “Maintain Data” permission can
display the bulletin board. Any user who has “Display” permission can display,
print, and schedule to print the contents of the bulletin board.

When logging onto the system, users will be notified of any messages on the
bulletin board. The notification message will indicate the last time the bulletin
board was updated, if any “High-Priority” message exists, and if the bulletin
board is 80% or more full. If a “High-Priority” message exists, the command
prompt will change to the following message:

■ High-Priority Bulletin Board Messages Entered:

After the next command is entered, the default command prompt returns to the
screen.

User Considerations

■ Only one user at a time may edit a message on the bulletin board.

■ The user must have the proper permissions to access the bulletin board.

DEFINITY Enterprise Com munications Server Release 5
Maintenance and Test for R5vs/si

Management Terminals

■ The user must maintain the information stored on the bulletin board. It is

555-230-123

the user’s responsibility to delete old messages. If the bulletin board is full,
any new messages overwrite old messages.

System Considerations

The Bulletin Board feature provides up to 3 pages of text for each message.
Each page is limited to 20 lines of text, and each line of text is limited to 40
characters per line. The first 10 lines of text on page 1 is reserved for Lucent
Technologies Service’s High-Priority messages.

System Bulletin Board Commands

The system commands “change bulletin board,” “display bulletin board,” and
existing commands in the user interface are provided for use in the Switch Based
Bulletin Board.

may be up to 40 characters per line. Each line of text has an associated date
field that is populated automatically by the system each time the line is modified.

The control keys used to edit existing feature forms must be used to edit a
message in the Switch Based Bulletin Board. The following characters are
allowed for use in the text field:

NOTE:

Tab characters are not allowed. The existing command line interface will
cause the cursor to move to the next field if a Tab character is entered.

If a user changes any lines that cause two or more consecutive blank lines, then
the bulletin board will be automatically reorganized (upon submittal). Two or
more blank lines will be consolidated into a single blank line. If a blank line is at
the top of a form, it will also be deleted. This function will help prevent holes in the
bulletin board screens as old entries are deleted.

To save a message entered into the bulletin board text field, the user must
execute the save translation comm and.

G3V3 software is required for the bulletin board feature. The bulletin board
feature, as described in this document is available in G3V4. The G3V3/G3V4
feature on the systems-parameters customers-options form need not be
enabled.

The system logoff procedure should be done any time the terminal is not being
used. This assures that system tran sl at i ons are not accidentally corrupted. The
monitor system command, when canceled, automatically causes a terminal
user to be logged off and, thus, prevents unauthorized use of the terminal. Use
the following procedure to log off the system:

Initialization and Recovery

When the system is powered up, or when it experiences a catastrophic fault that
interrupts its basic functions, the system undergoes a reboot. Besides “reboot,”

there are several less severe resets available to the system that allow it to recover
from disrupting errors. The user can initiate these resets by using the reset
system commands. These commands are used to manually restart the system at
various levels, depending on the required test activity. The reset system
commands are discussed in Chapter 8, ‘‘

Trouble-Clearing Aids’’.

Maintenance Commands and

A system is reset due to a loss of power, or via one of the following:

■ Reset commands at the administration terminal.

■ Maintenance software, from which the system can reset itself. (This

process starts when certain software and hardware errors are detected by
the softwa re.)

■ “Interchange,” which is a type of reset that can be scheduled as part of

daily maintenance in High or Critical Reliability systems.

!

WARNING:

When the system is rebooted or reset at level 2, 3, 4, or 5, all voice
terminal and attendant console features are adversely affected.
Users should be advised of services that are lost and that, as a

result, must be reactivated. See “Removing Power” in Chapter 5,

‘‘Routine Maintenance Procedures’’.

The administration terminal display and circuit pack LEDs indicate the progress
of the recovery process. LEDs are discussed in Chapter 7, ‘‘

LED Interpretation’’.

The sections that follow discuss successful system resets. For each level of
reset, a typical administration terminal display is provided. Note that any
hexadecimal numbers shown in parentheses, such as”(=8B89),” are only

examples and are subject to change. Subsequent sections discuss the recovery
process following an SPE-Down Mode and for "duplication interface-processing
element communication down."

NOTE:

If any of the diagnostic tests fail, the system may or may not function
properly, and the LMM may or may not proceed with the restart. If the LMM
does not proceed with the restart, the system goes into SPE-Down Mode. In
failure cases, the appropriate part (for example, the Processor circuit pack)
should be replaced.

NOTE:

Use and check the results of the set/get vector command found in the "Set
Commands" section in Chapter 8, ‘‘

Trouble-Clearing Aids’’, to determine how much time should be added for

the recovery levels. Also, if an update file is applied on a system reset, add
from 30 seconds to one minute to the recovery time for that reset.

Reset Sy s te m Intercha nge (High or
Critical Reliability Systems Only)

SPE-interchange (system hot start) is denoted by an "i" in the initcauses log. This
restart is used to transfer control from the Active SPE to the Standby SPE in the
least disruptive manner. Interchange (i) is the most transparent of all levels of
restart and causes no disruption of service to telephone users. This restart takes
fewer than two seconds.

NOTE:

The administration terminal is logged off. No diagnostics are performed,
and only the login prompt displays.

An interchange (i) can be performed in one of the following three ways:

a. System Technician-Demanded: using the reset system interchange

command

b. Scheduled Maintenance
c. Software-Requested: The software requests the interchange when it

determines that the Standby SPE is healthier than the current Active SPE

NOTE:

For most SPE alarms, interchange to the standby SPE is achieved using the
hot restart (i). However, there may be other alarms for which another restart
level (1 through 4) must be used to achieve a transition to the Standby SPE.

Procedure for SPE-Down Mode

Due to fatal hardware and software problems, it is possible for a syste m to go
into SPE-Down Mode. In this mode, the system invokes emergency transfer and
does not provide any other service. Moreover, while in this mode, the software
does not (or cannot) run at all. In a high or critical reliability system the system
goes into SPE-Down mode only when both SPEs go into SPE-Down mode.

There is an interface to the system by maintenance. The Processor circuit pack,
is responsible for maintenance in a standard reliability system. In a high or
critical reliability system, the maintenance is provided by the A-carrier
Duplication Interface (DUPINT-A) TN772 circuit pack with help from the
processor.

The administration terminal, which connects directly to the processor in a
standard reliability system and to DUPINT-A in a high or critical reliability system,
provides a very limited interface to the system. Technicians can display alarms or
restart the system. Only a subset of control complex alarms displays.

The first step is to determine the location of the problem. It is possible for two or
more circuit packs to have failed. It is also possible for a fatal problem with one
circuit pack to affect another circuit pack. This is especially true for the Processor
and Memory circuit packs, where a failure in one affects the other. All t hree of the
following methods should be employed to determine where the fatal fault lies.

1. Use display alarms command:
Issuing t he display alarms [a | b] command at the administration terminal

shows where maintenance thinks the problem lies. The alarms are a good
indication of why the system went down. They should be used with the
following two methods.

2. Observe red LEDs:
Observe the red LEDs on the circuit pack to determine where software or

processor firmware (LMM) had a problem.

3. Use the reset command:
In 286 system, issuing th e reset command (Standard Reliability system) or

the reset [a | b ] command (High or Critical Reliabilit y system) causes the
system to attempt a reset system 4. Observe all the diagnostics on the
screen, and note if the LMM has a problem with any of the diagnostics, as
this information should give a good indication of where the problem lies.

The procedure to get a system out of SPE-Down mode follows.

NOTE:

This is important! If you cannot complete the first step or have problems
with the maintenance interface, then the first step should be to replace the
Processor circuit pack. In a high or critical reliability system the DUPINT-A
circuit pack can also cause SPE-Down.

1. If the alarms indicate a tape failure, replace the tape or tape drive and go
to Step 3. Otherwise, verify that there is a good tape in the tape drive. If a
tape is not present or if either the tape or tape drive is defective, then
restarting the system using the reset command causes the system to go
down agai n.

2. In a High or Critical Reliabili ty system, select a carrier to repair first .
When it is possible to accurately determine the location of the problem,

use the display alarms [a | b ] command to display alarms for both SPEs
and check the red LEDs on the processor complex circuit packs. Select
the carrier where the red LEDs indicate the circuit pack alarmed. Bring up
the system on that carrier and then refer to Standby SPE Maintenance
documentation to repair the Standby SPE.

Procedure for Dup licat ion Interface —
Processing Element Communication
Down

In a High or Critical Reliabil i ty system, it is possible for bot h SPEs to stop
communicating with the A-carrier TN772 Duplication Interface (DUPINT-A) circuit
pack. Thus, the DUPINT-A, which is in charge of maintenance, prints the
following message on the administration terminal:

Duplication Interface-Processing Element Communication down

The system may continue to function on one of the SPEs. However, the system is
not able to provide any interface to the administration terminal.

If the system is still providing service, connect the administration terminal to the
Active SPE (check the amber LED on the Processor circuit pack). Then, if

software provides a login on the administration terminal, you can determine the
problems via the display alarms command.

If the system is not providing service, there is a problem with the Processor
circuit packs and/or DUPINT-A. Replace these circuit packs, one by one, until
the system starts functioning normally.
