INTRODUCTION:
Utilization of GIS technology has been extended into many different
fields. Today, automated Mapping and Facilities Management becomes the
new potential application for GIS, especially in telecomunication
area. PT. Telekomunikasi, as state own communication company in
Indonesia, acknowledged the potential of GIS technology to increase
their performance and services. For that purpose, as the initial
project, they decided to use ArcInfo and ARCVIEW to develop their GIS
application.
PT. Telekomunikasi Indonesia (PT. TELKOM) always aims to give the best services to their customers. For achieving that purpose, PT. TELKOM in conjuction with PT. Nusantara System International (PT. NSI), as the agent of Esri products in Indonesia, developed a GIS system for customer services. This system is called GIS SISKAMAYA, Siskamaya means System for Cable Administration and Service management that maintain Cabling network information.By developing this system PT.TELKOM expected to be able to give a better, faster and more accurate services for their customer. In addition, the potential information of the cable, network condition and trouble shooting, could be recognized easier by using this system.
OBJECTIVES:
The objective of the GIS Siskamaya development in PT.TELKOM was to
increase services to the customer and to maintain the network
information (cable). The detail objectives of GIS Siskamaya were:
- to give a better services to the customers, especially new potential customer - to make a better system for analizing the cable network - to perform a better network planning - to be able to do trouble tracing and shooting. - to prepare data for demand forecast - to maintain both graphical and attribute data easily - to integrate Graphical and alphanumeric data - to compute cabling administration - to handle network data problemsFor the pilot projects, two service points were selected from nine service points in Kandatel Bandung (Telecomuniation region office). They provided services for more than 30.000 telephone customers. This pilot project took four months to be completed and successfully implemented in November 1994.
SCOPE OF WORK:
Bandung Telecomunication Region Office has 9 (nine) service points that
have several stations for each service point. The 9 service points
have the same textual data base which stored in one mini computer (IBM
RS/6000). All service point linking to the same data
(textual/alphanumeric) in central database, therefore that only one
data that use by many operator in areas entire Bandung. The Share
Database concept was implies in this system.
GIS was develop for helping the operator to find the DP (Distribution Points) around the house which potentially take from. Before GIS, the operator has some mapping text that give information what DP could take from what street. But this mapping could not help if the house of new customer could not in a regular number (like most of the houses in Bandung). By GIS, the operator could identify the house easily and faster analyzing. Basically scope of work is what the operator do when the new customer come to have new telephone line, that requirement could describes into several way:
What descibes above are some scope of work of the operator, the front desk officer, that they called Front Room. Besides, there is a section that has duty to maintain the geographic data of cable network, called by Back Room. Back room should preparing data, taking a survey for updating and updated GIS data maps and textual for which will use by Front Room. After the updating process, Back room should should submit that data to Service points PC's , which has local data maps (for each Service Point) through Wide Area Network.
The another important thing of the scope are: Although the service points are spread in the city but they all access the same the Cable Network Information which store in The Central database in in INGRES format. The operator in each Service Point uses Pcs which online connecting to the Central database which placed more than 5 Km from Service Point.
To make this Workstation and PC's spread in whole Bandung area linking each other those machine should integrate in a Network and uses some telephone line to connect among them.
STRUCTURE HIERARCHI
The Cable network has hierarkhi as follows:
STO - Otomatic Telephone Central, describes as a points. This is the central of the telephone in a region.
SSP - Cable House, the place where the secondary cable was collected before distribute.
DP - Distribution Points, describes as a points. This is where line telephone distributes to customer house
DATA MODEL:
This GIS project was taken 2 (two) service points as pilot project, Centrum and Turangga. Both are plotted by 57 grid maps of 1 : 1000. The geographical data of those area devided into several layers that design will be usefull for customer application services, some of layer those are:
It is not the same as house number, DP's and SSP should appears as annotation and an attributes as well. Because this DP and SSP should linking with the DP and SSP in Central database.
Besides this regular hierarkhi data, that was some irregular hierarkhi, a DCL (Direct line area). Not like the DP which distribute in Secondary cable and SSP from Primary, DCL distributes in Primary Cable. That means the DCL function same as DP but the information store in the level of SSP. That is why this database should design very carefully to fit with the existing database.
In the Central Database, alphanumeric data stores in INGRES format in Mini Computer. This textual data was develop long time before GIS develop, then the important things that the GIS should used the existing data which has been entry and design before. This kind of work was really not the simple as if the textual data was design same time with the GIS data.
In this case the design of textual data could not change at all, and the GIS should develop follow on the textual information. To integrate between existing and new data, then some new field created in the existing database as keys for linking to the geographic data.
SYSTEM CONFIGURATION:
To design system that integrate application and data in Workstations
and PC's also in a Wide Area Network with Online connecting and the
cheapest way are really not easy. Fortunatelly, about middle of 1994,
ArcInfo - the Best solution, publish the new client server concept
packet module, ArcView 2 which any in PC's format. Therefore the system
could design to fulfill the PT.TELKOM needed, and the configuration
could describes as follows (see Software Configuration, SoftKonf.gif):
Basically the application development in this pilot is divided into 2 kinds of application.
CONCLUSION:
