What is GIS?

A geographic information system (GIS)integrates hardware, software, and data for

capturing, managing, analyzing, and

displaying all forms of geographically

referenced information.

GIS allows us to view, understand, question, interpret, and

visualize data in many ways that reveal relationships,

patterns, and trends in the form of maps, globes, reports,

and charts.

A GIS helps you answer questions and solve problems by

looking at your data in a way that is quickly understood and

easily shared.

GIS technology can be integrated into any enterprise

information system framework.

Three Views of a GIS

A GIS is most often associated with a map. A map, however,

is only one way you can work with geographic data in a GIS,

and only one type of product generated by a GIS. A GIS can

provide a great deal more problem-solving capabilities than

using a simple mapping program or adding data to an online

mapping tool (creating a "mash-up").

A GIS can be viewed in three ways:

3/20

The Database View: A GIS is a unique kind of database ofthe worlda geographic database (geodatabase). It is an"Information System for Geography." Fundamentally, a GISis based on a structured database that describes the world in

geographic terms.

1.2. The Map View: A GIS is a set of intelligent maps and

other views that show features and feature

relationships on the earth's surface. Maps of the

underlying geographic information can be constructed

and used as "windows into the database" to support

queries, analysis, and editing of the information.

3. The Model View: A GIS is a set of information

transformation tools that derive new geographic

datasets from existing datasets. These geoprocessing

functions take information from existing datasets, applyanalytic functions, and write results into new derived

datasets.

By combining data and applying some analytic rules, you

can create a model that helps answer the question you have

posed. In the example below, GPS and GIS were used to

accurately model the expected location and distribution of

debris for the Space Shuttle Columbia, which broke up upon

re-entry over eastern Texas on February 1, 2003

GIS in TelegraphyTelegraphic GISGIS in Telecommunication

Geographical information system in telecom industry plays an

important role. GIS can be a great planning and decision-making

tool for telecom industries. GIS technology allows telecom to

enhance a variety of application ranging from engineering

application, customer relationship management, workforce

management and location based services. GIS helps telecom tocreate competitive advantage by optimizing installation,

maintenance and tracking of network assets.

Telecom companies typically operate in maze of location-specific

data. To manage and solve their operating issues smoothly, telecom

companies require information on current and future needs of their

customers, customer locations and assets deployed at various

locations. GIS helps to analyze location-specific information for

network infrastructure management, wireless coverage and assets

management.

Telecommunication networks are characterized by vast

geographical expanse and large number of features. Continuously

evolving telecom technology and tremendous competition has

necessitated very tight financial and inventory controls,

maximization of utilization of installed physical inventory and high

quality of uninterrupted service to the customers. Telecomcompanies succeeding in meeting these challenges continue to

grow, thereby further increasing these challenges. GIS based

Telecom applications are ideally suited to meet all of these

requirements

Finally the paper emphasises that GIS systems within Telecom

utilities can provide facilities for fault tracking, customer care,

Planning and efficient management of a large distributive network

and more importantly provide a framework for better integration and

analysis of relevant facility information derived from several sourcesin graphics environment.

History of Telecommunications

The history of telecommunications is a story of networks.

Alexander Graham Bell on his honeymoon wrote of a "grand

system" that would provide "direct communication between anytwo places in [a] city" and, by connecting cities, provide a true

network throughout the country and eventually the world

(Winston, Media Technology, p. 244). From the telegraph to the

telephone to e-mail, electronic communication has extended farther

and reached more people with increasing speed. The advent of the

Internet in combination with a satellite system that covers the

entire surface of the earth has brought us closer to the "global

village" envisioned by Marshall McLuhan in the 1960s.

The variety of media included under the umbrella of

"telecommunications" has expanded since the early twentieth

century. The term was adopted in 1932 by the Convention

Internationale des Telecommunications held in Madrid (OED). At

this point, the telegraph, the telephone, and the radio were the only

widely used telecommunications media. The United States, the

point of origin for only one of these three (Bell's telephone), soon

came to dominate the telecommunications industries. The RadioCorporation of America (RCA) was created in 1919, three years

before Britain's British Broadcasting Corporation (BBC). By 1950,

the American Telephone and Telegraph Company (AT&T)

provided the best telephone service in the world. American

television led the way after World War II (19391945). Then, in

the early 1980s, a new device was introduced: the personal

computer.

At the outset of the vast telecomm infrastructure project, Reliancemanagement recognised the importance of providing high quality ofuninterrupted service to the customers. Continuously evolvingtechnology and tremendous competition has necessitatedmaximisation of utilization of telecom inventory and tight inventorycontrols.

GIS platform with a dedicated telecommunication application is theoptimum solution since it can store the network inventory in ageographical manner. Interfacing with network, O & M and customerfacing systems enables to meet the business requirementssuccessfully. Some of the main requirements expected to be met bythe GIS / Telecom application are:

Plan, design and engineer Network and expansion Modeling of (OutSide Plant) OSP and (InSide Plant) ISP items

up to port level Placement of Trenches, Cables, Structures and facilities in the

OSP Facility layouts, equipment placement and port-to-port

connectivity Inventory management including equipment assignment Repository of As Built and survey data Provide network data to OSS / BSS systems Answer service activation / provisioning queries Cable fault localisation Several Sales, Marketing and Service fulfillment related

functions

Selection of GIS Platform & Telecom Application

13/20

Technical evaluation of all existing out-of-box packages was done

with one week hands-on experience wherein ease of learning and

operation, efficiency of CAD functionalities etc. were tested by

operators.

Detailed technical discussions involving client functional

capabilities, RDBMS, version management of the GIS platform

were carried out.

Ease of data conversion, telecom feature modeling and other

functions were evaluated. Efforts in customisation, after sales

support etc. were also considered.

GIS Use in Telecommunications

To be competitive, telecommunications providers depend on a

smoothly functioning work flow process that integrates

information for marketing, demand forecasting, engineering,

customer management, operations support, and fleet management.

Although telecommunications providers generally have the same

needs for information, how the work flow is organized can vary

significantly from company to company.

Historically telecommunications companies have used an

assortment of information systems-some developed in-house, some

purchased-that were never designed to work together. When these

systems were implemented, there was no perceived requirement

for information sharing. Today telecommunications companies

operate networks that have equipment from multiple vendors andlease bandwidth and antenna sites from other companies. Mergers

with, or acquisition of, other companies require the incorporation

of, or at least interaction with, completely foreign networks.

13


14/20

The need for information sharing within companies and

interoperability between systems has been recognized by the

telecommunications industry for a long time. Originally founded in1865 as International Telegraph Union, the International

Telecommunications Union (ITU) promotes standards in

equipment that guarantee generalized interconnection between

communication systems. To improve interoperability, ITU has

developed the Telecommunications Management Network (TMN),

a method of standardizing business organization. This hierarchy of

support systems specifies interoperability through the use of

industry-standard protocols. Geospatial applications need to

support this same level of interoperability if GIS is to work wellwithin this TMN-structured environment.

Many current applications of GIS in the telecommunications

industry began as departmental tools that worked within a well-

defined scope. These GIS-based tools have helped automate

business processes and increase the efficiency of operations. The

following sections describe how telecommunications companies

have integrated GIS into the overall work flow.

Business driver

GIS based telecom application requires large investment, manpowerand time in data creation and deployment. Full benefits of suchsystems can only be realised when the Telecom GIS systembecomes an integral part of the OSS / BSS solution and theorganisational work processes are designed with GIS as an essentialpart of such integrated OSS / BSS solution. Based on automatic flow-

through business processes, such integration provides maximumvalue addition in terms of

Single point data entry and elimination of redundant databases, Minimal human intervention in data creation, Improved response to network events, Improved response to customers,

resulting in improved overall efficiency of the enterprise.

Integration with OSS

Telco application on GIS platform is the data master for all networkinventory and network infrastructure data as well as network relatedreference data.

Network inventory data includes equipment, cards and physicalports.

15


16/20

Physical configuration data includes physical circuits and crossconnections.

Infrastructure includes facilities & other OSP data like trenchesand cables.

The logical configuration is created in OSS based on information fromTelco GIS and customer data entered in CRM.

The data volume of physical network inventory, connections andfacilities runs in to a few million records for a large network. Singlepoint data creation with automatic uploading in OSS ensuringsynchronising of the two databases saves several thousand man-hours.

As a result of this, permanent link is automatically establishedbetween OSS and GIS through primary keys, allowing on-the-flyspatial queries to be handled between the two systems. Questions byOSS and field staff requiring information of nearest active electronicsfacility or nearest manhole based on visual or textual address inputare answered in seconds.

Detailed requirement assessment and data mapping is performedjointly by OSS and Telco application team. At this stage, followingdetails are frozen

All network element and facility naming conventions Modeling details for both physical and logical configurations Overall integration scheme and middleware API signatures on either side Error handling and database synchronisation issues Test plans & test cases with expected results

We have successfully implemented an application for uploading the

network inventory and physical links data to OSS. Enclosed Figure 1indicates Flowchart of Data Upload to OSS. Following are theimportant steps involved:

Inventory changed since last upload is transferred to interfacetables using a difference cursor with 'ADD', 'DELETE' or

16


17/20

'MODIFY' flags. Middleware adapters are triggered to starttransfer to OSS.

Inventory data is validated against of reference data in OSS. A'SUCCESS' or an error code is returned to interface table.

The 'SUCCESS' is also posted to the versioned tables to avoidretransfer of the data during the next dump.

Due to the difference in representation of links in OSS compared toGIS / Telco application, transfer of links is more complicated. TheLinks are populated in the interface tables as follows:

Every connected port is scanned and a network trace made.

17


18/20

Each complete trace is given a 'Set ID' and each piece of cablewithin a set is given a 'Sequence Number'.

A table is populated where every 'Set ID' is mapped to theOTDR port, which monitors that link.

From the first table, OSS picks up 'FROM' port from the firstrecord and 'TO' port from the last record of the set.

From the second table, OSS picks up information of which Linkis monitored by which OTDR port.

The task of error checking, corrections and transferring the dataagain to OSS is manual and tedious. GIS / Telco application operatormay need to check 3,000 records after each dump. This task isfacilitated by specially developed GUI, which displays the errormessage for each inventory item, allows user to zoom to the feature

as well as select and start editing the same version, which createdthe inventory.

OSS integration for Fault localisation is one of the most important andhighly integrated applications that has been developed. The link toOTDR port mapping table loaded from GIS database forms a key tothis automatic flow through process. Refer enclosed Figure 2indicating the Flowchart of Automatic Fault Localisation. Following arethe important steps involved:

OSS commands the OTDR to provide optical distance to fault.The OTDR returns the optical distance of fault via OTDR serverto OSS.

OSS passes the same along with OTDR port and a Fault ID toTelco application on GIS platform for locating the fault on map.

GIS / Telco application places the fault marker, calculates all thenecessary attributes and publishes the fault location to Intranet.Simultaneously, the information is returned to OSS for furtheruse like trouble ticketing, history etc.
