Three variants have been developed:

•APT 210 12/1 R1 for France.

•APT 210 12/2 R1 for Norway and Spain.

•APT 210 12/3 R1 for the Netherlands and Switzerland.

Note that the countries referred to above were the first to implement the

system. Numerous other countries have subsequently selected AXE local

exchanges.

APT 210 12/1

APT 210 12/1 was originally developed for the French market. It is used

when installing new local AXE exchanges or when upgrading existing

local AXE switches requiring ISDN functionality integrated with POTS.

APT 210 12/2

APT 210 12/2 is a general application, developed initially for the Norwe-

gian and Spanish markets. It is used when installing new local AXE

exchanges or when upgrading existing local AXE exchanges requiring

ISDN functionality integrated with POTS.

In terms of ISDN, both basic rate access (BA) and primary rate access

(PRA) are provided.

2.2 Description of Operational Activities

Operation is the normal, everyday running of the exchange when every-

thing is working as it should. The purpose of the tasks included in the

operational activities is to adapt the exchange to the continuously chang-

ing demands placed on it.

AXE 10 Basic Operation and Maintenance Activities

603802-EN/LZM 112 17 R1

Operational activities, (see figure 2.3), are normally initiated by work

orders. Work orders may be the result of operator or subscriber demands.

In either case, a work order instructs the AXE staff to carry out modifica-

tions to the exchange, that are required for its adaption to the newly arisen

needs.

Work orders are executed in accordance with the procedures defined in the

AXE B-Module exchange documentation.

Operation staff communicate with the exchange by means of the AXE

Input/Output system.

The following are a number of examples of operational activities:

•Changing subscriber data, e.g. activating a new subscriber line, provid-

ing a new service or changing the subscriber class of an existing sub-

scriber

•Changing routing data, e.g. initiating a new route

•Recording statistics, e.g. traffic recording, such as monitoring of traffic

measurements for a period and reporting or, in some cases, evaluating

the result.

2.2.1 Maintenance Activities

The purpose of maintenance activities is essentially the prevention and

correction of faults.

One can subdivide maintenance activities into two types:

1. Preventive Maintenance entails the performance of a set of routine

tasks that involves checking for suspected fault sources of faults and

their neutralization before such sources give rise to serious system

consequences.

2. Corrective Maintenance involves responding to actual faults by

removing or repairing their immediate causes. Upon the occurrence

of a fault, the system will notify the staff by generating an alarm and

alarm printouts.

Staff may also be notified of the exsistence of a fault as a result of sub-

scriber complaints. Information relating to faults external to the exchange

may also be received from subscribers.

The Ericsson Maintenance Philosophy, Controlled Corrective Mainte-

nance (CCM), seeks to achieve a balance between these two types of

maintenance.

Whatever the source of information, once the existence of a fault is

known, action must be taken to eliminate it. Maintenance Staff use the B-

Module of the exchange documentation to interpret fault information.The

B-Module also contains the procedures, Operational Instructions (OPIs),

required when dealing with faults, (see figure 2.4).

Figure 2.4

Maintenance Activities

When performing the tasks outlined by an OPI, Maintenance Staff com-

municate with the exchange using the AXE command language, often

referred to as the Man-Machine Language (MML).

AXE 10 Basic Operation and Maintenance Activities

803802-EN/LZM 112 17 R1

The following are a number of examples of various maintenance tasks:

•Fault-finding, testing and repair of subscriber lines

•Fault- finding, testing and repair of trunks

•Fault-finding, testing and repair of the GSS and SSS units

•Maintenance of the AXE power supply and power distribution system

•APZ Maintenance.

3.1 Overview of the Exchange Library

3.1.1 AXE 10 Documentation Principles

Before proceeding with the description of the exchange library and its con-

tents, a summary of the main principles employed in AXE 10 documenta-

tion are provided below.

The system employed for document identification is built on a close rela-

tion between the products found in the system and the documents associ-

ated with each product.

The system hierarchy defines the products found at the different levels.

From the point of view of documentation identification, all products from

the system level to the individual printed circuit board level are treated

equally, (see figure 3.2).

Chapter Objectives

After completing this chapter the participant will be able to:

• Describe the general structure of the Exchange Library and main-

tain the library through the use of the OPI “Handling of the

Exchange Library”

• Describe the layout and contents of the B-Module and its use

• Understand AXE 10 document numbering

• Understand the basic principles of AXEUSE, FIOL and DocView

• Describe the AXE 10 command structure

• Identify the operational activities that are to be performed based on

information that is supplied in a specific work order and the con-

tents of the associated B-module.

Book Title

Figure 3.2

System Structure

A product is identified by a unique Article Code. An individual Article

Code or individual identity consists of a number of letters and digits that

are combined in accordance with the numbering system rules. The num-

bering system classifies and groups the products and documents in accord-

ance with their use, system association, their location in the product

hierarchy and their factual contents. Pre-defined basic numbers and classes

are registered in a database which is continuously updated to include new

items.

Figure 3.2 illustrates the hierarchial construction of the system and dis-

plays some examples of the logical construction of the identification sys-

tem:

•The AXE system has article codes including APT and APZ codes.

•All APT subsystems have article codes including ANT prefixes and all

APZ subsystems have article codes including ANZ prefixes.

•The Function Block Group represents a recent addition to the product

level structure in which Function blocks having related functionality

are grouped together, (CRT and CRZ). The Function Block Group level

does not exist in APT 210 08/R5.

•All APT function blocks have article codes including CNT prefixes and

all function blocks in APZ have article codes including CNZ prefixes.

•All function blocks in subsystem ANT 216 xx have article codes

CNT 216 yy zz.

Different versions of the same product are distinguished by the Revision

State. Revision states are advanced in accordace with a given set of rules

and is related to an important product, namely interchangeability, e.g. Arti-

cle Code: CNT 216 1012, Rev. State: R3.

A document is identified by a prefix and an unique number. Different ver-

sions of the same document are distinguished by a revision letter. Docu-

ment numbers for documentation relating to products usually consist of

the decimal class and the article code.

The decimal class indicates the type of document, and the article code

indicates the product associated with the document , (see figure 3.4).

A document structure exists for each product category which specifically

states the documentation required by the different product handling

phases, i.e. design, manufacturing, etc.

Certain document types are mandatory for every product. Others are

drafted when necessary, depending on the product’s functions, design and

characteristics. Figure 3.5 shows an example of document structure for a

function block.

3.2 The Structure of the Exchange Library

All documents relating to the exchange are gathered together to form the

exchange library. The contents range from descriptions of the layout of the

building and floor plans for the exchange equipment to instructions on

how to trace and eliminate software faults. Such a wide range of material

obviously requires some sort of structure so that the information is easily

accessible by AXE staff.

The documents are distributed throughout a set of functionally defined

modules, each of them being contained in one or more binders. Some of

the longer, less frequently used modules may be stored in microfiche for-

mat to save space. Today, it is all stored on CD-ROM.

With reference to the basic operation and maintenance of the exchange,

the modules vary a great deal in terms of importance; some will be con-

sulted daily, others never. With this in mind, we will now describe the

modules to a degree of detail corresponding to their importance as regards

the O&M job:

Four of the modules, likely to be used by AXE staff on daily basis, will be

are fully described. They are:

A-Module Library Survey.

B-Module Operation and Maintenance Manuals (Operational

Instructions, Command Descriptions, Printout Descrip-

tions and Application Information).

C-Module Exchange Description (hardware, cabling etc.).

Another three modules are used occasionally by the O&M staff and hence

are dealt with more briefly. They are:

D-Module Functional Product Documents (software descriptions and

flowcharts).

E-Module Software Documents (source and assembly codes).

F-Module Hardware Documents (magazine and circuit layouts).

I-Module Exchange Data (MML commands configurating an

exchange), also known as the Data Transcript.

Finally, there remain six modules which are practically never needed by

the staff dealing with basic O&M. They are listed below:

G-Module Mounting Details.

H-Module Installation Test Instructions.

K-Module Power Supply Documents.

M-Module Signalling Inter-work Information.

S-Module Software Fault Location.

T-Module Correction of Central Software.

3.3 Handling the Exchange Library

The OPI “Handling of the Exchange Library” found in sub-module B01,

deals with the procedures for:

•Checking documents received

•Inserting and replacing documents

•Filing delivery notes

•Borrowing documents from the exchange library.

Library maintenance may at first glance appear to be a trivial task. Reality

is however quite the contrary. The complexity of the information coupled

with the need for its frequent updating would quickly lead to complete

chaos without the existence of and compliance with strict document main-

tenance procedures.

Electronically stored information, (e.g. DocView, AXEUSE) allows the

saving of countless hours of work each time the documentation requires

updating. Instead of thumbing through reams of paper you simply load a

new CD- ROM disk into your PC.

3.4 B-Module Overview

The B-Module (OPERATION AND MAINTENANCE MANUALS).

The B-Module is the most frequently consulted module in the library. It

consists of instructions for administrative routines, product handling, man-

machine communication, supervision, fault reporting, fault location and

elimination, exchange data modification, spare-part handling, operational

reporting, etc.

The information contained in this module is used both by O&M staff in

their daily work and by the operator when, for example, modifying

exchange data.

The major portion of the B-Module concerns the Operational Instructions

(OPIs) which guide the staff in carrying out their various tasks.

Operational instructions generally refer the staff-member to Command and

Printout Descriptions. Although the experienced user usually manages

with the Operational Instructions alone, others require the help of the

Command and Printout Descriptions.

Because the instructions and descriptions are of a comprehensive nature

and handle a variety of different functions, the B-Module is subdivided

into seven sub-modules. These are listed below:

B01 General Operational Instructions.

B02 Operations Instructions.

B03 Maintenance Instructions.

B04 Test Instructions.

AXE 10 Basic Operation and Maintenance Activities

16 03802-EN/LZM 112 17 R1

B11 Command Descriptions.

B13 Printout Descriptions.

B14 Adaptation Directions, Application Information.

Note: In certain instances the B-Module is subdivided as follows:

•B03 contains B01 - B03

•B14 contains Adaptation Directions

•B15 contains Application Information.

3.5 Using the B-Module

3.5.1 O&M Documentation Structure

We have mentioned earlier that the B-Module is divided into seven sub-

modules, B01 to B04, B11, B13 and B14. The major portion of these sub-

modules is made up of Operational Instructions (OPIs). With the help of

flow charts provided in the OPIs, the operator is guided through the opera-

tion and maintenance tasks in a step-by-step fashion. The information

included in each submodule is summarized as follows:

Submodule B01 (General Operational Instructions):

•Administrative routines

•Product-handling instructions for magazines, printed board assemblies,

cables, I/O devices and spare parts

•Man-machine Communications including operating instructions for

panels, I/O devices and alarm system and command language rules.

Submodule B02 (Operations Instructions):

•Subscriber-associated changes

•Changes in the exchange data

•Collection of statistics

•Output of charging data

•Size alteration

•Functional changes.

Submodule B03 (Maintenance Instructions):

•Time schedule for inspection

•Instructions for performing inspection of panels, I/O devices, sub-

Exchange Handling Basics

03802-EN/LZM 112 17 R1 17

scriber line test-equipment

•Procedure in event of alarm

•Procedure in event of fault-observation

•Instructions for fault-localization and repair.

Submodule B04 (Test Instructions):

•Testing the APT, APZ, and power equipment in an in-service exchange.

Submodule B11 (Command Descriptions):

•Functional descriptions of commands

•Brief descriptions of parameters

•Parameter combinations and formats

•Examples

•Expected types of printout after command input

•Fault codes and their interpretations

•Command category numbers.

The commands are listed in alphabetical order.

Submodule B13 (Printout Descriptions):

•Functional descriptions of printouts

•Print headings

•Interpretations of abbreviations

•Procedure to be followed upon the receipt of a printout

•Printout groups.

The printouts are listed in alphabetical order.

Submodule B14 (Adaptation Directions):

•Adaptation Directions

•Application Information

•Command Tables

•Various lists including parameter lists, subscriber categories, alarm cat-

egories, size alteration events, end-of-selection codes (in both alpha-

betic and numerical order).

Adaptation Directions contain detailed functional descriptions of the com-

mands and their parameters.

Application Information consists of documents which provide detailed

information, for each function block, as to the allowable value ranges that

may be assigned to parameters.

Command tables are rarely used.

3.5.2 Locating the Documentation

As we know now, the B-Module fills a big part of the exchange library.

Each B-submodule consists of one or several binders. They are divided

into sections (grey dividers). Each section is divided into subsections

(green dividers) and sometimes the subsections are divided into parts

(orange dividers). The dividers are numbered from 0 to 9.

The first binder of each sub-module contains a document list. This list pro-

vides the contents of all the binders contained in the particular submodule.

3.5.3 Accessing Information in the B-Module

The steps involved in accessing information in the B-Module are as fol-

lows:

1. Finding the Title of the Operational Instruction

There are two ways in which the operator is assigned a task and each way

contains the relevant Operational Instruction.

•If the task is a response to an alarm, the operational personnel is to

access the OPI containing the same title as that found on the Alarm

Printout.

•All other tasks are initiated as the result of Work Orders, the contents of

which will indicate the name of the necessary OPI.

Whatever the origin of the task, the OPI will be found in submodules B01

to B04:

Type of Task Submodule

Administrative activities B01

Handling I/O devices B01

Operational tasks B02

Maintenance B03

Testing B04

2. Finding Additional Information

Operational Instructions direct the staff to Command Descriptions

(CODs), found in B11, by listing the commands that may be needed. The

Command Description usually suffices, but if more details are required,

they are to be found in the Application Information document identified by

the Command Receiving Block named in the COD.

This course includes a number of operational activity related exercises

which will provide practice in the use of the B-Module.

3.6 Using FIOL / DocView

DocView is a document retrieval tool for EDML-based Ericsson docu-

mentation, such as the Operation and Maintenance (O&M) documents.

EDML stands for Ericsson Document Mark-up Language. EDML was

developed by Ericsson and is an internal documentation standard.

DocView replaces the printed document binders and offers features for

browsing, searching and printing. The application is intended for any user

(designer, test and maintenance personnel) requiring flexible access to the

documents stored in the DocView databases.

The information stored in this document databases is easily accessed.

There are several hierarchical levels and a possibility to use context sensi-

tive searches. Hypertext and Find features are provided to speed up access

to requested document. Any portion of the information may be accessed at

speeds that far surpass manual look-ups in printed binders. AXEUSE /

Dynatex will replace DocView and FIOL in the future.

Chapter 4 describes in detatailed the handling of DocView.

3.7 Using AXEUSE / Dynatext

Up to now, Ericsson has provided FIOL as the only standard communica-

tion program for local AXE Operation and Maintenance. FIOL was origi-

nally designed as a test tool for internal usage within Ericsson, no focus

was originally placed on the needs of AXE 10 end-users.

AXEUSE (AXE USer Environment) is a Microsoft Windows application

that provides multi-channel communication with target systems. It is a

successor to FIOL and is a communication program combined with a

“Browser” for an On-screen Operation and Maintenance manual, running

under the MS Windows Graphical User Interface, GUI.

The AXEUSE package includes a copy of the Dynatext Browser, an appli-

cation which enables the user to view “electronic books”. Using the Dyna-

text Browser, the user can read documentation pertaining to the

application system.

The approach used when designing AXEUSE was to create an environ-

ment which would increase the productivity of the Operation and Mainte-

nance personnel. This is achieved by a graphical user interface designed in

accordance with current standards that meet known customer needs. The

environment also includes on-line documentation retrieval , Dynatext,

which provides context-linked information retrieval removing the tedious

task of browsing through the pile of binders just to perform a maintenance

task.

AXEUSE is described in more detail in chapter 4.4 of this document.

AXE 10 Basic Operation and Maintenance Activities

20 03802-EN/LZM 112 17 R1

3.8 The Exchange Log Book

AXE Operation and Maintenance Staff use the Exchange Log Book to

record all important events.

The following are examples of occurrences that should always be

recorded:

•High-priority alarms

•Operational disturbances

•Intervention and fault-repair performed on the APZ and common units

of APT, e.g. the GSS

•Output of call-charging records and statistics

•Activation of new lines and extensions

•Activation of new traffic cases and routes

•Addition of new functions, programs or data.

Some occurrences and actions, such as the repair of faults - especially

those which were traced to the exchange itself - need to be entered into the

log book after the exchange is returned to service.

The log book should always contain information concerning the latest

dump, together with details of any changes made in connection with the

dump, and any other information that could be useful in restoring the

exchange after a breakdown.

The OPI for using the Exchange Log Book is entitled ”Keeping a Journal”

and is located in submodule B01 of the B-Module.

3.9 The Command Language and Printouts

Communication between the AXE system and the AXE staff is carried out

by means of commands and printouts.

The staff members enter commands to perform O&M tasks in the

exchange and the exchange responds with printouts. In addition, the

exchange will automatically generate printouts to indicate faults or other

important events within the system.

The dialogue between the staff members and the AXE system requires a

language. This language is called MML (Man-Machine Language) and is

written in accordance with ITU-T recommendations.

Exchange Handling Basics

03802-EN/LZM 112 17 R1 21

3.9.1 Command Structure

In general, commands are structured in the following manner:

COMMAND CODE:PARAMETER NAME=PARAMETER VALUE;

Command Code

The command code defines the task to be executed. This code normally

consists of 5 characters:

XXYYZ

XX indicates the function group, YY specifies the function, and Z is an

abbreviation of the verb indicating which action will be taken, e.g. I for

Initiate, P for Print etc.

Parameters

Parameters are supplied following the command code in order to specify

how and where the order defined by the command code should be exe-

cuted.

If more than one parameter is necessary, the parameters are separated by

commas. The order in which different parameters within the same block

are arranged is not significant.

Commands may be written:

•Without parameters IOROP;

•With parameters (see below).

Commands requiring parameters may be written as follows:

•Without a value IODAC:ATT;

•With a single value EXRPP:RP=1;

STDEP:DEV=LI2-5;

•With several values EXRPP:RP=1&3&5;

STDEP:DEV=LI2-1&-3&-5;

•With a range of values EXRPP:RP=1&&5;

STDEP:DEV=LI2-1&&-5;

Square brackets [ ] denote optional parameters.

Braces { } enclose alternative parameters and indicate that one of the

parameters must be entered when using the command.

Square brackets which enclose braces imply that it is not necessary to indi-

cate any of the alternative parameters.

Command Descriptions (CODs), found in B11, are used to describe the

parameter combinations that may be used in conjuction with a particular

command.

AXE 10 Basic Operation and Maintenance Activities

22 03802-EN/LZM 112 17 R1

Printouts

There AXE system incorporates two types of printouts:

Automatically initiated printouts and command-initiated printouts:

1. Automatically Initiated Printouts

•Alarm Printouts

These are initiated either by a fault in the system or by supervision limits

having been exceeded due to disturbances. The printout usually follows

visual, or visual and audible alarms, depending on the alarm level.

•Alarm List Printouts

An alarm list printout is received automatically at intervals specified by

command ALLTC. The alarm list output contains a list of all active alarms.

The alarm list can be printed manually at any time by entering the com-

mand ALLIP.

•System Restart Printouts

A system restart printout is received after each system restart. The mes-

sage SYSTEM RESTART will be printed on all terminals.

2. Command-Initiated Printouts

This type of printouts can be divided into:

•Check Printouts

Check printouts repeat the command exactly as it is entered by the techni-

cian. The technician is required to confirm or inhibit the execution of the

command. To confirm the command, a semi-colon (;) is entered. If any

other characters are entered, the command will be inhibited. A check print-

out is given primarily by commands that could affect the traffic and by

commands that have been corrected by the technician.

Example:

<SYREI:RANK=rank;

SYREI:RANK=rank;

<; (to confirm the command)

Exchange Handling Basics

03802-EN/LZM 112 17 R1 23

•Procedure Printouts

A procedure printout is received immediately after entering a command.

Examples:

EXECUTED

ORDERED (F1 to release and wait for execution)

NOT ACCEPTED (followed by the reason)

The procedure output acknowledges a command input or a cancellation. A

command is always acknowledged by a procedure output or by a result or

answer printout.

•Answer printouts

Answer printouts are received directly after a print command.

Example:

EXEMP:RP=40,EM=0; (Print command)

EM DATA (Answer printout)

RP TYPE EM EQM TWIN CNTRL PP STATE

40 RPM6A 0 ET7-0&&-31 41 PRIM WO

END

•Result Printouts

Result printouts are given as a result of a command but normally at a later

time and always on a new page. The result printout is always preceded by

the procedure printout “ORDERED”.

Example:

ORDERED (F1 to release)

SIZE ALTERATION RESULT

SAE BLOCK NI FCODE UCODE

504 BT2 6

END

The title of the result printout is provided for interpretation purposes, see

binder B13.

3.10 Chapter Summary

•A product within the AXE system is identified by a unique article code

e.g. ANT, CNT, CRZ etc.

•The decimal class indicates the type of document, and the article code

indicates the the product associated with the document

•The function group CRZ is a new addition to the product level structure

in AXE Local 12.4.

•A, B and C-modules are normally used by the AXE- staff on daily

basis.

•D, E, F and J modules are used occasionally.

•G, H, K, M, S, and the T modules are practically never used by the O &

M staff..

•If the task is a response to an alarm the operational staff is to access the

OPI with the same title as that found on the alarm printout

•The log book should always contain the latest activities within the

exchange and any other information that could be useful in restoring the

exchange after a breakdown

•The command code defines the task to be executed. This code normally

consists of 5 characters in accordance with the ITU-T standards.

4.1.2 Seizure and Release of Terminal

When not in use, the terminal is normally in an idle state and data can nei-

ther be sent to nor received from the exchange.

The process of establishing a link between the terminal and the AXE sys-

tem is called seizure.

The process of disconnecting the link between a seized terminal and the

AXE system is called release.

Seizure and release can be performed manually or automatically. Manual

seizure and release are performed either by using special keys or charac-

ters. Figure 4.2 illustrates a number of examples:

Figure 4.2

Examples of Seizure and Release

4.1.3 The Label Printout

Immediately after manual seizure of a terminal, the system transmits a

standard printout called Label Printout (also called the Header). As seen

in figure 4.3, this Label Printout contains:

•The operational state of the processor, in the figure: WO means the cen-

tral processors are working in parallel

•The exchange identity, in the figure: TRX A, i.e. Training Exchange A.

•The terminal identity, in the figure: AT-4

•The current date and time, in the figure: 951106 1545.

Communication with the System

Figure 4.3

Label Printout

4.1.4 Ready Indicator

Immediately after the Label, the left bracket which is called Ready Indica-

tor (also called Cursor or Prompt) is transmitted by the system to indicate

that it is ready to receive a command.

4.1.5 End of Text Character

The end of a block of characters, i.e. the command, is indicated by the

semicolon “;” which is called End of Text Character.

4.1.6 The Check Printout

When the AXE system receives a critical command, it sends the command

back to the terminal where it is presented as a Check Printout. The staff

member who entered the command can then confirm or inhibit it. The

command is confirmed by a semi-colon.

4.1.7 Authority Check

Sometimes access is allowed to the system only by authorized persons.

This is performed via the use of Passwords.

If an authority check is required, the system will automatically order the

operator to enter a password.

Even if the check is not required, it may not be possible for everybody to

use all existing commands. Each terminal can be given a key which limits

the number of possible commands to certain groups. Only authorized per-

sons will be allowed to change the key. An attempted execution of a

restricted command results in the message “COMMAND RESTRICTED”.

4.1.8 The Time-Out Printout

When a seized terminal is not used for a certain time (typically five min-

utes), the system releases the terminal automatically and transmits a Time-

Out Printout.

4.1.9 Blocking and De-blocking of the Terminal

If the AXE system detects a fault in the I/O path, the terminal is automati-

cally blocked, and an alarm is issued. The system will normally de-block

the terminal when the fault is cleared.

Manual removal of the block is also possible from the blocked terminal by

entering a character and then pressing ENTER. The character may be dif-

ferent for different terminals. For example, for the HP264 terminal, the

character is a question mark “?”.

Blocking may also be performed manually, via command. This is done e.g.

before testing a terminal. After the test, the terminal has to be manually de-

blocked.

4.1.10 Queue System

Some requested printouts are not generated immediately. In such cases, the

system compiles the information and puts it in a queue for later output.

Output of a queue starts automatically when the I/O device is released.

Output may also be ordered when in command mode by sending a special

character. Printouts may be sent to more than one terminal if needed.

4.2 Communication Program FIOL/DocView

4.2.1 Basic Functions of FIOL/DocView

FIOL is a program which makes it possible to use a personal computer as a

terminal for communication with the AXE system. The main advantage of

FIOL is that it simplifies command handling.

FIOL is an abbreviation of the program name, “FIle transfer and online

editor”.

DocView replaces the printed document binders and offers features for

browsing, searching and printing the documents. This application is

intended for any user needing a flexible access to the documents stored in

DocView databases (CD-ROM).

4.2.2 Window Screen

A window appears on the screen when the program is started. Three lines

are found at the bottom of the screen (see figure 4.4).

•The status line

•The command line

•The pre-defined main menu function-keys line.

Communication with the System

Figure 4.4

The FIOL Window

The window consists of a maximum of 22 lines which can be divided into

two windows when the user is communicating with two channels at the

same time.

4.2.3 The Status Line

The status line consists of the following information:

•Active channel CH0/CH1

•Text mode INSERT(i)/

OVERWRITE(o)

•Printer status ON/OFF

•Name of the log file

•Name of the transmit-file

•Communication mode BUF/TTY

Communication may either be performed in BUFFER mode (BUF) or in

ONLINE mode (TTY). In BUF mode it is possible to edit the command on

the command line before it is sent into the system. In the TTY mode the

characters are sent immediately to the system when entered.

4.2.4 The Command Line

The command line is a combined command and error-message line. All

commands are entered from this line. The twenty latest commands sent are

stored in a circular buffer. The commands can be reached with the up and

down keys, and will be presented on the command line when they are

stepped.

The function “END OF TEXT” is implemented in FIOL for entering com-

mands by just pressing the ENTER key.

4.2.5 The Function Keys

The function keys are pre-defined in the main menu as follows:

F1: Release. This is the “END OF TRANSMISSION” function when

it is implemented in FIOL. This function releases the terminal, i.e.

marks a seized terminal as idle.

F2: This function key works as a switch between channel window 0

and window 1. The STATUS LINE displays the active channel.

FIOL allows concurrent communication with two connected

systems.

F3: Entrance to the VIEW MENU.

−Scroll up/down on the screen

−Page up/down

Communication with the System

4.3 Using the Communication Program FIOL /

DocView

The DocView application is designed to replace the paper document bind-

ers in much the same way as does AXEUSE .

Any documentation available in EDML (Ericsson Document Markup Lan-

guage) format can be handled electronically with DocView.

The DocView Browser allows one to easily browse through and search for

information contained in Operation and Maintenance documents (B-Mod-

ules). Savings in time and effort are remarkable when using DocView in

comparison with the handling of paper documents.

Figure 4.5 shows the hierarchy of the document information levels that are

used in the DocView databases for an Application System, AS.

DocView Information Levels

Recent configuration changes make it possible to run DocView in a Win-

dows environment. This way, you can have other tools (PlexView, FIOL

etc.) running at the same time and maintain the adequate speed of operat-

ing. CD-ROM drives enable it to change the database beeing used quickly.

4.3.1 The User Interface

The following image is displayed when DocView is started,

(figure 4.6):

Figure 4.6

DocView User Interface

The DOS view only allows keyboard control. Help is available through the

Help key <F1>. Pressing the <Alt> or the <Ctrl> keys will display the

code executed by the function keys.

There are several pop-up windows that provide DocView operational

information such as document information, previous documents, book-

marks and printing options.

4.3.2 Loading a Document from a Database

All documents are loaded for view directly or indirectly through an index

(document list). The background is changed on a colour monitor when

viewing the main (Content List) or another index for easy identification.

A document index is handled by DocView as an ordinary document except

when a line containing a valid document or database reference is recog-

nized. The line contents are then highlighted (Inverted) and act as a cursor.

Communication with the System

03802-EN/LZM 112 17 R1 35

Pressing the <Enter> key when the cursor is positioned to a requested doc-

ument will cause the document to be loaded for viewing. If a database is

selected, the corresponding index file is loaded. Any number of document

databases can easily be accessed from DocView. The database files can be

updated independently of each other. The maximum number of simultane-

ously loaded document files is set to 10.

<Shift> - Displays index of previously viewed documents

Pressing the <shift F10> keys will cause a pop-up menu to be displayed

which contains references to previously viewed documents. The menu will

display document title (as given in the document index), page reference

and document type. Document type usually consists of two to three char-

acters, e.g. COD=Command Description.

The display below is an example of the contents of the pop-up menu fol-

lowing the load of five database documents:

Figure 4.7

List of Previously Opened Documents

Enter the number of a document or use the arrow keys <↑↓> to make a

selections from the menu. Then press the <Enter> key and the selected

document is loaded and displayed.

<Shift-Home/End> - Switch to previously viewed documents

Pressing the <Shift-Home> or the <Shift-End> key-combinations will

switch the currently displayed document to a previously viewed document,

found in the list of currently loaded documents, i.e. previous/next docu-

ment in the list. The current position in the document is retained when

switching from document to document.

However, this function does not switch back to a directly accessible docu-

ment index. These indexes are always easily accessed through function

keys <F5...F10>.

<F10> - Return to main document index for the databases

Pressing the <F10> function key will cause DocView to return directly to

the main index, displaying the content list of the accessible document data-

bases. As an option, FIOLSYSTEM features may optionally be listed in

the main index and may be executed directly from that index.

4.3.3 Searching Functions

Page Search Using the Content List

When viewing a document with a content list, the list is recognized by

DocView and can be used as a fast way of jumping to the correct page in a

document. A cursor (inverted line), see figure 4.8, is visible on a line with

a page reference. A direct jump to the page is launched with the <Enter>

key.

Figure 4.8

Page Search

Search for a String in a Document

A search is started by pressing <F3> and typing the search string into the

search text field. Pressing the <Enter> key will initiate the search.

Note: a search for a string can only be performed inside one document at a

time.

Remember the following rules when searching for document strings:

•The Search feature is not case sensitive

•The Search is started from the line following the current cursor position

on the viewed page and continued until the end of the document is

reached

•Search direction may be changed. Press the <Shift> key before press-

Linked to

page 3

Communication with the System

03802-EN/LZM 112 17 R1 37

ing the <Enter> key to change search direction.

•The last ten strings searched are kept in a circular buffer and can be

used again with the arrow keys <↑↓>

•The Search can also be started from the beginning of any directly acces-

sible document index by selecting the appropriate index using the <F5>

- <F10> function keys.

Find a Document from a Document Index

This feature is used for finding a specific document from one of the

directly accessible document indexes. When a requested document title is

known, the document title can be rapidly searched for in a selected docu-

ment index.

The Search is performed as follows:

First press <F4> and type the searched title into the search text field. Then

press <Enter> to search inside the current index or select the appropriate

index using the <F5> - <F10> function keys.

When using the Search feature, keep in mind that:

•The search is started in a selected document index from the page fol-

lowing the Content List and continues until the end of the document is

encountered

•The Find feature differs from the Search feature in that the Find feature

skips the Content List and only the beginning of the line is matched

with the string in the search text field.

<A...Z> - Find line in content list

The alphanumeric keys (A...Z) can be used in the content list as a fast

search forward on a line starting with the same character(s) as pressed.

Also the numeric keys (0...9) can be used when the find feature is acti-

vated.

The character find is not case sensitive and the entire content list is

searched regardlessof the length of the list. When viewing the document

index for a COD (Command Description), extra database options have

been added to speed up COD document load time regardless of its position

in the document index.

4.4 Using the Communication Program AXEUSE

4.4.1 General

AXEUSE is a Microsoft Windows application that provides multi-

exchange communication to target systems, such as the Ericsson AXE 10

exchange. It offers the following communication features:

•Interactive communication through the use of command line, command

history buffer and quick command files

•A facility for the recording and transmission of command files

•On-screen and printer logging of communications, and a communica-

tion log file recording facility.

In addition, AXEUSE provides the following range of support services:

•Access to on screen documentation using the included DynaText

Browser application

•Access to TBT (Technology Based Training) sessions from within the

application

•Online help and online tutorial.

4.4.2 The DynaText Browser

The AXEUSE package includes a copy of the DynaText Browser, an

application which enables you to view “electronic books”. If requested,

the Browser is loaded on to your PC as part of the AXEUSE installation

process. If installed, the Browser application will be loaded whenever you

start AXEUSE. It runs in background mode until you select it.

Using the DynaText Browser, you can read documentation regarding your

application systems, which is stored on the On-Screen Documentation

CD-ROM.

4.4.3 The AXE Application Window

After you have started AXEUSE (double-clicked on AXEUSE ), the appli-

cation window will open and occupy part of your Windows desktop (see

figure 4.9.).

The menu bar is located along the top of the application window and pro-

vides access to the AXEUSE command set. Many of these commands can

also be activated by function keys.

Communication with the System

03802-EN/LZM 112 17 R1 39

Figure 4.9

The AXEUSE Application Window

Beneath the Menu bar is the Toolbar, a series of icons providing fast

access to the most commonly used AXEUSE functions.

The Quick Commands icon is used to display the current quick command

file.

Pressing the Connect/Release icon will cause the application to transmit

the connect character to the AXE 10 system. Pressing the same icon while

the exchange is connected will release the connection.

Along the bottom of the application window is the Status Line, which dis-

plays a range of information regarding the currently active exchange win-

dow.

The Command Line may be used for direct entery of commands to the

AXE 10 system.

The Command History List button recalls commands previously entered

on the command line. Up to 40 commands may be stored in the history list.

4.4.4 Interactive Communication

Interactive communication with the AXE 10 system is performed via

Exchange Windows (see figure 4.10). You may have up to nine exchange

windows opened at the same time, one window for each of the ports COM

1-9.

After opening an exchange window you can then connect that window to

the AXE 10 system, so that commands may be sent to that exchange port.

When finished, you may release and close the relevant exchange windows

individually.

Exchange windows can be re-sized, re-positioned and minimized to icons

if required.

4.4.5 The Active Window

Although multiple exchange windows are opened and simultaneously con-

nected to the AXE system, only one of them can be the active window,

(see figure 4.10). The active exchange window is the one which may initi-

ate exchange-related commands or actions.

Figure 4.10

The Exchange Windows

You activate an exchange window by clicking on any part of it. The title

bar with the exchange name will then be highlighted.

4.4.6 The Command Line

AXEUSE allows you to type in commands and parameters, and send them

directly to the AXE 10 system. You input these on the command line of the

active exchange window, (see figure 4.11). Press the ENTER key to trans-

mit them. Command-line editing features are provided. The most recently

entered command is highlighted and can be copied to the command line.

4.4.7 The Command History List

A Command History List is associated with a command line. The list is

made up of a buffer which contains the last 40 commands you have

entered on the command line.(see figure 4.12).

To open the command history list, click on the Command History List But-

ton (see figure 4.9) at the bottom right hand corner of the exchange win-

dow. You can access the history list at any stage, and recall and re-transmit

any previously entered command.

Figure 4.12

The Command History List

4.4.8 Quick Commands

The Quick Commands function enables you to store the most commonly

used commands and parameters in one or a number of files. To access the

quick commands function, click on the Quick Commands Icon

(see figure 4.9).

Each file could represent a different task or job. While performing that job,

you can pre-load the appropriate file into the quick commands dialog box.

The file may be edited within the quick command dialog window.

AXE 10 Basic Operation and Maintenance Activities

42 03802-EN/LZM 112 17 R1

4.4.9 Command Files - Recording and Transmission

AXEUSE enables you to record command files - ASCII files containing

one or a sequence of AXE commands and any associated parameters - for

transmission to the AXE 10 system.

Transmitting a command file to the AXE 10 system is faster and more con-

venient than typing the relevant commands and their parameters a second

time on the command line of an exchange window.

You can create and edit command files within AXEUSE, or you can use a

word processor or text editor which offers the option to save files in ASCII

format code.

A command file is always transmitted from a connected exchange win-

dow, and the window responds to the transmission in the same way as it

would had the contents of the command file been typed on the command

line.

If the situation so requires, you can temporarily interrupt command file

transmission to the AXE 10 system.

To facilitate automatic testing, command files can be created and sent to

the AXE 10 system.

4.4.10 Logging Communication

AXEUSE offers three different options when logging communication with

the AXE 10 system. In each case it is irrelevant how the communication

takes place. Whether a command is entered on the command line, recalled

from the command history list, selected from the quick commands file or

transmitted from a command file, the full details of the communication are

logged by AXEUSE.

Options for logging communications are briefly described below.

The Exchange Window

All commands sent from AXEUSE to AXE 10 pass via an open and con-

nected exchange window, and that window always displays full details of

the communication. (see figure 4.13).

Figure 4.13.

Exchange Window

Entered command

Feedback from

target system

Communication with the System

03802-EN/LZM 112 17 R1 43

Vertical and horizontal scroll bars are provided with the exchange window

to enable you to move through a list of communication details, particulary

useful when the entire area of text does not fit within the window.

Printer Logging

At any stage of communication between an exchange and the AXE sys-

tem, you can log details of the communication to a print spool. The infor-

mation may then be printed directly.

Communication Logs

You can create a communication log file for recording the commands sent

to the AXE system and the feedback generated by the system in response.

The log file will record all commands and feedback, regardless of whether

the commands are entered directly on the command line, recalled from the

command history list, sent as quick commands, or transmitted within com-

mand files.

You can temporarily interrupt the recording at any stage and resume it

again when appropriate (see figure 4.14 ).

It is recommended that you add the file extension .log to the name of

your log file when saving it.

Once you have recorded and saved a communication log, you can display

the log on the screen or output it to a printer.

Figure 4.14

Open a Log File Dialog Box

4.4.11 On Screen Documentation

Whenever you start AXEUSE on your PC, the browser application is also

started. It runs in the background until you select it.

Using the DynaText Browser, you can read documentation regarding your

AXE 10 Basic Operation and Maintenance Activities

44 03802-EN/LZM 112 17 R1

application system. This is stored on the CD-ROM which you will have

received from your supplier. Of course, the on-screen documentation CD-

ROM must be loaded via your PC’s CD-ROM drive in order to enable

AXEUSE to access the information that it contains.

You can access the Browser from within AXEUSE, or you can simply

switch between AXEUSE and the Browser using the Windows task-

switching facility.

4.4.12 Interactive Access

AXEUSE provides the user with interactive access to the DynaText

Browser.

Whenever feedback containing a command-related fault code is displayed

in the exchange window, the program can automatically retrieve and dis-

play the relevant Command Description.

4.4.13 Access to Technology Based Training (TBT) Sessions

TBT sessions may be accessed from within AXEUSE, there is therefor no

need to terminate the current application when entering a training session.

AXEUSE is, at the moment, supplied with three TBT courses: C7 Signal-

ling in AXE, C7 in the Telecommunications Network and IOG11 Hard-

ware.

Future additions on TBT will include operator aids applicable to the han-

dling of emergency situations.

4.4.14 Online Help and Tutorial

In addition to printed documentation, AXEUSE offers on-line help for all

commands and commonly performed functions. You can access this mate-

rial at any stage by pressing the standard Windows help key, F1.

The online tutorial enables you to learn the basics of AXEUSE by practis-

ing interactively with a copy of the real application.

Communication with the System

4.5 Connection to TMOS

Communication with TMOS, (Telecommunication Management and

Operation Support) presupposes a standard for the sending and receiving

of information. TMOS uses several different standard communication pro-

tocols to communicate with AXE 10.

•X.25 for the link communication (Layer 3)

•MTP for application communication (Layer 4 - 7).

The physical connection to TMOS is performed via one of the physical

ports in the IOEXT magazine located in the IOG11 (Input / Output Sys-

tem).

Communication between the AXE 10 and TMOS, (see figure 4.15), can be

divided into the following five traffic cases:

•MML- Commands

•Delayed Responses

•Spontaneous Reports

•File output from the AXE 10 Exchange

•File information from TMOS to the AXE 10 Exchange.

4.5.1 MML Commands

The MML language used for normal handling of AXE 10 Exchanges can

also be used for communication via TMOS.

Immediate Response

All MML commands result in some sort of immediate response from the

AXE 10 Exchange. Immediate responses are received as ASCII characters

and may therefore be displayed via character terminals.

TMOS designates immediate output as an immediate response.

There are four types of immediate responses:

•Procedure Printouts

•Interactive Printouts

•Answer Printouts

•Check Printouts.

4.5.2 Delayed Responses

A response is often delayed due to the fact that the action requested

requires the AXE system to collect data (traffic recording etc.), which

takes a varying amount of time.

4.5.3 Spontaneous Reports

This report category represents reports produced by the AXE system that

were not solicited by the TMOS system. Alarm situations are examples of

situations resulting in such reports.

4.5.4 File Output from the AXE 10 Exchange

File outputs from AXE 10 are binary ASCII files and are converted by the

TMOS system (statistic measurement etc.).

4.5.5 File Information from TMOS to the AXE 10 Exchange

Any files that are similar in syntax to the file output from the AXE 10 sys-

tem can be sent from TMOS to the AXE 10 Exchange.

Chapter Objectives

5.1 Mechanical Structure

5.1.1 Introduction

The mechanical organization of the AXE system is based on a concept

called the Packaging System or the BYB-Structure. This system offers a

high degree of flexibility which is well suited to the AXE system’s overall

modularity. Packaging system size standardization contributes to the sim-

plification of the handling required during the variousd phases of design,

manufacture, documentation, installation, and operation and maintenance

activities related to the AXE system.

The AXE equipment is delivered in Magazines equipped with Printed

Board Assemblies. These magazines are the basic building blocks of the

packaging system.

The magazines are installed on Shelves housed in Racks or Cabinets. The

racks or cabinets are arranged in Rows in the exchange room.

Chapter Objectives

After completing this chapter the participant will be able to:

• Locate Hardware units in the exchange through the use of com-

mands

• Identify the operational activities that are to be performed based on

information in a specific work order and the contents of the associ-

ated B-Module.

AXE 10 Basic Operation and Maintenance Activities

50 03802-EN/LZM 112 17 R1

5.2 Development of the Packaging System

5.2.1 BYB 101 and BYB 102

The first packaging structure developed was called BYB 101. Certain

objectives were particularly considered during the design of this package:

•The structure was to be suited to electronic equipment units made up of

integrated circuits, miniaturized electromechanical components and

power supply units.

•It was to be possible to use computerized aids to facilitate the design,

production and documentation of the system.

•The processing time and cost were to be kept as low as possible.

•The structure should not to restrict the use of existing and future com-

ponents.

•Cooling was to be achived by natural air circulation (selfconvection)

for most of the cabinets, (With the exeption of the IOG and CP).

Basically, the BYB 102 has retained the basic structure of its predecessor,

the BYB 101. Its primary objective was to simplify installation methods

and operations, thereby reducing installation time.

Modified elements of the BYB 102 structure may be applied when exist-

ing BYB 101 installatons are expanded.

Both BYB 101 and BYB 102 structures use racks to house the shelves car-

rying the magazines.

5.2.2 BYB 202

The BYB 202 is designed to meet the requirements for a flexible cabinet-

type structure. The designers of this system seized the opportunity, while

maintaining the basic design of the BYB structure, to make a number of

improvements:

Screening

The BYB 202 cabinet structure ensures effective protection against ESD

(Electrostatic Discharge) and EMI (Electromagnetic Interference). The

cabinets are electrically screened to comply with international standards.

The front doors have special features to optimize both EMI and air ventila-

tion(see figure 5.2).

Hardware Orientation

Figure 5.2

Screening

Heat Dissipation

The main objective in the thermal dimensioning of the cabinets was to

keep component temperature as low as possible. An efficient combination

of series and parallel natural convection, with its known advantages (no

noise, no fan maintenance, etc.), was used to achieve greater heat dissipa-

tion than that achieved with earlier designs (see figure 5.3).

Cabinets requiring extreme heat dissipation make use of fans that support

natural convection.

AXE 10 Basic Operation and Maintenance Activities

52 03802-EN/LZM 112 17 R1

Figure 5.3

Heat Dissipation

Earthing

The combination of the material and the excellent mechanical design of

the contact points employed in the earthing system of each cabinet, cou-

pled with the inter-cabinet earth connection scheme, ensures good zero-

level stability.

Cable Running

As in the case of rack design, the exchange cables can be run in screened

cable chutes mounted on top of the cabinets or between a raised deck and

the actual floor of the switching room (see figure 5.4).

Cable Chutes

Interior cabinet cabling is distributed so that it is run in both the horizontal

cable chutes and in the vertical space at the left side of the cabinet.

AXE 10 Basic Operation and Maintenance Activities

54 03802-EN/LZM 112 17 R1

Earthquake Resistance

Anchoring arrangements and the design of the cabinet ensure resistance to

earthquakes, in line with international requirements.

5.2.3 The Building Module

Instead of inches or centimetres, Ericsson uses a standard unit of length

which is called a “Module”, designated (M) in mechanical structures.

1 M = 0.1 Inch = 2.54 mm

This unit is a bit too small for practical use, so another unit which is called

a “Building Module”, designated (BM), is used.

1 BM = 16 M = 1.6 Inches = 40.64 mm

5.3 The Cabinet

Cabinets are manufactured in two different widths. The narrower of them

is 720 mm wide, has only one door, and is used for magazines of up to 12

BM. The broader version is 1200 mm wide, has two doors and is used for

magazines up to 24 BM ( See Fig. 5.5).

Figure 5.5

Cabinets for magazines of 12 BM and 24 BM

The cabinets can be delivered in two heights; 2135 mm or 1810 mm.

The depth of the cabinets is 400 mm.

There is a maximum of 6 shelves in BYB 202 cabinets.

Required ceiling height is, on a raised floor, a minimum of 2697 mm, and

with overhead cabling a minimum 3100 mm.

The cabinets may be mounted in double-sided rows (back-to-back), in sin-

gle sided rows, or single against a wall. The required maintenance aisle is

minimum 800 mm.

The rows, cabinets and shelf numbering are shown in figure 5.6. The row

numbering (3-digit) is marked on the end of the cabinet at the beginning of

each row. The first digit is normally the floor number, the second and third

digits indicate the actual row number. In this example, this particular row

is located on the first floor in row no. 21.

Figure 5.6

Row, Cabinet and Shelf Numbering

Each cabinet has its own number at the front upper corner which indicates

its position within the row. Numbering starts at the beginning of each row,

which is always indicated on the layout by a line.

The shelves are labelled alphabetically, with the top shelf as A, the second

as B, and so forth, down to the letter F as we use a maximum of 6 shelves.

5.3.1 Magazines

A magazine consists of two main components:

•The board frame including slots that hold and guide the printed boards

•The backplane which contains the magazine’s internal wiring and cir-

cuit board connectors.

The magazines with circuit boards are placed on the shelves. The maga-

zines correspond to function units and therefore vary in size, (see figure

5.7).

Figure 5.7

Magazines in BYB System

The packaging structure permits flexible positioning of the magazines, i.e.

they can be placed side by side or on top of each other, or on a combina-

tion of the two arrangements, (see figure 5.8). This permits the cabinets to

be equipped in the easiest and most economical way.

Positioning of Magazines

The magazines are interconnected by means of front connections and can

thus be moved or replaced without necessitating any change of the cabinet

layout.

The magazines are assigned type-codes BFD XYZ, in which:

X denotes magazine type,

= 1 for magazine with PCBs or

= 2 for magazine devices such as power units.

Y denotes board spacing,

= 1 for 6M or

= 2 for 8M.

Z denotes magazine width,

= 2 for 3BM,

= 3 for 6BM,

= 4 for 9BM, etc.

Looking at figure 5.9 we see how the magazines are differentiated by their

width, and thus the number and type of printed circuit boards (PCBs) they

can contain.

Each magazine is equipped with the PCBs that are required by the particu-

lar function unit in which the magazine is included. Each PCB has its pre-

defined position in the magazine. All magazines are equipped with one or

more power boards to supply power to the individual magazine. These

power boards have a toggle switch for turning power on and off. Some

boards are equipped with a fuse mounted on the power plug.

5.3.2 Magazine Devices

These are units which require a space-equivalent of an entire magazine

and are placed on shelves in the same way as magazines containing PCBs.

Examples of these units are the DC/DC converter unit, the ringing genera-

tor, the distribution unit, etc.

5.3.3 Printed Circuit Boards (PCBs)

The Printed Circuit Boards are installed in slots in the magazines. Each

board has room for two connectors at the back side and two connectors at

its front, (see figure 5.10). When the boards are put into place in the maga-

zine, they are plugged into the backplane by means of the back connectors.

Figure 5.10

The front connector positions on the printed boards in a magazine are allo-

cated in two rows (A and B), (see figure 5.11).

The standard PCBs are assigned type-code ROF 13 ... except for CP

boards which are assigned ROF 16 ....

Depending on the size of the components mounted on a board, boards

require magazine space amounting to 6M or 8M. Components are

mounted only on one side of the board.

5.4 Localization of hardware units

In order to locate the physical position of a Magazine, RP, EM, DEV etc,

in an exchange, an operator can use the command EXPOP and study the

printout for localization of the suspected unit.

Example:

EXPOP: TSM=TSM-B-2;

Time Switch Module number 2 in the digital group switch, plane B, is

pointed out.

New equipment added to an exchange must be initiated via the command

EXPOI.

Example:

EXPOI:DEV=KR-0&&-15,POS=CITY-24B-6-C;

For KR individuals 0-15 the following position is defined: Building CITY,

row 34B, section 6 and shelf C.

Position information defined in the system can be removed by command

EXPOE.

Example:

EXPOE:DEV=KR-0&&-15;

Position information for the Hardware entity KR 0-15 is removed.
