2. INTRODUCTION

This document presents the remote inventory functionality. This function is available at the OMC-R

and allows for the operators to perform hardware and firmware inventories. The document does take

into account all external tools (database..) that can be developed to run with using the files available

at the OMC-R.

Section 4.1 gives the general principals of this function

Section 4.2 gives the main requested data

Section 4.3 explains the interfaces (operator, external tools)

3. ABSTRACT

The Remote Inventory feature allows the operator to get hardware and firmware information from the

OMC-R. This information is used for retrofit, deployment or maintenance. The benefit is to avoid on

site visits.

The Remote Inventory data are reported to the OMC-R by the BTS (EVOLIUM™ BTS and micro-

BTS) which are very numerous and spread out on the field.

The operator can get these data in two ways, automatic or on demand, the “on demand “ mode being

still available when the automatic mode is selected.

Among the reported data are information that are very useful in case of retrofit or maintenance

actions, for example: the site name, the board exact location, the serial number, the part number and

the variant.

Sending the data to external tools is possible thanks to an ASCII file format. This format is the same

as the one obtained using a Local Maintenance Terminal (LMT) at BTS site, which is the way to get

inventory data until release B6; existing external tools can thus be re-used.

4. FEATURE DESCRIPTION

4.1 General principles

The Remote Inventory objective is to get inventory data from the most numerous network elements

that are spread out on the field. These are the EVOLIUM™ BTS and micro-BTS that store the

inventory data in a non-volatile memory.

These data are necessary for the operators in a number of cases to prepare interventions on sites

(such as new release introduction or replacement of a faulty board). With the Remote Inventory

feature, data on equipment are collected very quickly and precisely, without the need to go on site.

The operator has then the information allowing him to determine the exact number and locations of

boards to be replaced before introduction of a new release, or the detailed characteristics (especially

the functional variant and ICS) of a faulty board needing replacement.

The inventory data retrieval can be processed in different ways, automatic or on demand, according

to the users needs and after a BTS hardware audit (following an add or remove a TRX) in order to

cover the main changes between two automatic acquisitions. With the automatic mode the inventory

is made automatically, periodically (using a defined period given in days). With the “on demand”

mode the inventory is performed on operator request who can choose the option “forced”.

When choosing the automatic mode, the operator can modify the acquisition period from one day to

30 days (7 days is the default value). The inventory data retrieval is usually made during non-busy

hours and does not disrupt the other data retrieval (alarms, performances,…). Nevertheless, the user

has the capability to stop the automatic mode at any time (lock/unlock inventory). In that case, the

operator can still retrieve the inventory data by using the “on demand” function. Lock can be useful

during long operations such as migrations.

When inventory data are requested (automatic or “on demand” mode), the BTS polls its inventory

EEPROM to get the information and sends back the remote inventory data if some change has been

performed since the last request. In the “on demand” mode with the forced option the inventory data

are systematically sent to the OMC.

In the OMC-R, inventory data are stored in files (one file per BTS) that are all located in the samedirectory and that can be exported to external inventory tools via FTP. These data can also be

displayed at the OMC-R man machine interface, on operator request.

4.2 Inventory Data

Inventory data are available in each Replaceable Item (RIT) of the EVOLIUM™ BTS (BTS Step 1

and Step 2, micro-BTS). They are saved in flash EEPROM and so protected against power failure.

When requested (automatic or on demand mode), the BTS builds a remote inventory file that

includes information coming from the RIT EEPROM and some other information coming from the

BTS itself.

The operator can get the following information with the remote inventory function (The whole remote

inventory file content is not given in this overview document):

• the site name

• the equipment commissioning date

• the board exact location (this means, its rack number, shelf number and slot number)

• the board serial number, the part number and the variant.

This information helps the operator to perform maintenance actions (such as changing a faulty

board) or retrofits.

4.3 External interfaces

• Operator interface

The views in this section are not obviously given in an exhaustive way.

Inventory data can be partially (for one failed equipment, BTS, board or RIT, for example) or fully

displayed at the OMC-R. The operator can easily navigate from (to) its equipment views to (from) its

remote inventory view and display all the data relative to a BTS or the data relative to one board just

by selecting respectively on the equipment view the appropriate BTS or board.

The Remote inventory equipment view, global management view and configuration views are

The automatic Remote Inventory administrative state (lock or unlock the automatic RI), the period

(acquisition period when in automatic mode), the activation time (time when the inventory is made

when in automatic mode) and the first activation are configurable at the OMC-R. This is made

through the configuration view (also called automatic scheduling view):

From the equipment view, the operator has the capability to request the Remote Inventory

information for all the supervised BTSs, for all BTS of the selected BSC or for all BTSs of several

selected BSCs.

• Interface with external tools

The remote inventory files available at the interface are ASCII files (using INVENTAR format), so that

they can be easily read and edited by external tools.

5. MAIN IMPROVEMENTS OVER B5 AND B6 RELEASES

The Remote Inventory feature is available with the BSS release B7. Compared to B5/B6, it brings the

following benefits:

- Reliability : inventory data are reported directly (periodically if requested) by the BTS to the

OMC-R (through the BSC which is transparent), so the operator is insured to have the right

information. In order to keep the OMC-R at a high level of performances, Alcatel recommends

the automatic mode with a seven days acquisition period.

- Saving money : it is no more necessary to go on site to get hardware and firmware information

before doing a retrofit or a maintenance action.

6. HARDWARE IMPACT

There is no hardware impact.

7. INTERACTION WITH OTHER FEATURES

There is no interaction with other features.
