First billing system was developed in COBOL for fixed line subscribers. TCIL has further implemented state of the art billing systems and OSS for all the needs of the Telcos based on robust Relational Data Base Management System (RDBMS). Billing and customer care centre, mediation, pre-paid and post-paid systems and implemented it for a GSM Network. Other billing systems that TCIL has successfully implemented for its clients in the recent past include:
E-mail over Telephone
Other Software Projects
TCIL has provided software expertise by way of providing TCIL engineers for enhancement and maintenance of RASS (Record Automation for Special Services) software. The RASS and billing for telecom special services implemented in the cities of Melbourne, Sydney and Perth is an on-line automated Management Information System designed to improve provisioning, maintenance, recording and management of special services in department of telecom.
TCIL engineers have developed Listing Information System (LIST) for BellSouth Information Services Inc., USA, and implemented it in Southern Bell and South Central Bell, the largest Bell operation company in USA having more than 20 million subscribers. The basic function of the system is to process various interfaces to facilitate updating in the Yellow Pages and White Pages (Telephone Directories) as well.
TCIL has also done re-engineering of caller-identifications (CI) and addition of new functionality of caller-identifications which authorizes the use of calling card of Bell operating company, and also does the pricing of such phone calls. It also provides the archival system for AUTO COLLECT, PAYPHONE, OPSLAN and VOXMIX services.
TCIL engineers have also worked on implementation and maintenance of Total Network Data System / Trunking (TNDS/ TK), a product of Bellcore Inc., USA for all the 13 telecom districts having over 1 million subscribers. The TNDS/TK process the measurement of the traffic in telecom network.
TCIL experts have executed projects with Unisource Business Network (UBN) BV, Netherlands, a joint venture of three PTf's, namely Netherlands, Switzerland and Sweden for National Value Added Network Services (NATVAN). The software tool was developed to verify the correctness of billing records generated in the production environment of NATVAN. It provided interactive query interface through which the operators can query the charge ticket database to obtain the usage of the various services for a given user. TCIL also developed the tool to test the implementation of Prestel Gateway (PG 2.2) protocol on Access Points (AP) in the network of NATVAN and the tool to test the implementation of Call Control Center Access Points (CCC-AP) protocol on Call Control Center (CCC) in the network.
TCIL engineers have executed the project in association with PKI, Nuremberg (Germany) for developing PHAMOS (Philips Advance Management Operations System), a Network Management System (NMS) under SDH (Synchronous Digital Hierarchy) Networks. Based on CCITT recommendations and OSI and ETSI standards. TCIL engineers have executed project with SEL, Alcatel, Stuttgant for integrated network management syste.
TCIL business analyst engineers were involved in development of comprehensive integrated database for Guineas Peat Aviation (GPA), PLC.
