TCIL has been contributing to its business in Telecom domain through implementation of various value added services (VAS) to enhance the profitability and productivity. TCIL has been continuously working to identify new tools to add value to the existing offerings of the Telecom service providers. Some of the work undertaken by TCIL are as follows:

Billing and Customer Care Systems

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:

• Setting up of customer billing system for a Telecom operator.

• Subscriber line management system and mediation, billing and accounting system for Public Telecom Corporation.

• Setting up of integrated billing and customer care system.

• System for pre-paid services for cellular services comprising of Customer Care Management System (CCMS) and Recharge Card Management System (RCMS) modules.

E-mail over Telephone

TCIL has also commissioned the e-maii over telephone system for a leading Telecom operator of India. This innovative project is to provide e-mail over telephone for the fixed line subscribers, who do not own PC's. With e-mail over telephone service, the subscribers can access their mails and send SMS both over telephone and Internet. No computer and internet connection is required when mails are accessed over a fixed line or cellular phone. Voice commands are used to navigate through the mail menu. This is enabled by built in speaker independent telephony speech recognition software. It recognizes the commands / sentences with keywords (e.g. to open the inbox, say "In box" or "Go To Inbox" or "Open My Inbox" spoken by user and accordingly gives instructions to the application program. Voice commands like Read Mail, Next Mail, Previous Mail, Reply Mail, Delete Mail, Forward Mail, etc can be used over the phone and these commands are executed. A text to speech engine converts the mail to natural sounding synthesized speech and reads out to the user over the phone. The system is capable of reading out Text, HTML, MS Word and play voice attachments.

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.

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.
