After the 1991 economic policy made a shift from a closed economic model to a market-oriented model. The government invited private sector to participate in reforming its telecom sector. However, the government took a half-hearted approach in overhauling the legal and regulatory regime, suitable for competitive regime or in framing the 1994 Telecom Policy. Competition was allowed in cellular an...

The fiber laser concept is proven technology for telecom applications where its single mode performance and reliability is essential. Newer generation diode-pumped fiber lasers are using pump diodes especially developed for telecom applications and therefore offer excellent controllability of the laser pulse length and pulse frequency. In recent years the output power of fiber lasers has increa...

Even though ICT convergence is a well-established and adopted concept, there is no consensus about the underlying software engineering approach to convergent ICT systems. Telecom engineers and software engineers traditionally use different approaches when developing services and applications. A main question is whether or not the differences are justified and should be maintained in the context...

This paper presents an overview of WADE (Workflows and Agents Development Environment), an open-source platform for agentbased BPM (Business Process Management) that has been adopted in Telecom Italia for mission-critical systems since the early 2000s. First, we sketch the main features of WADE and outline its internal architecture. Then, we describe WANTS (Workflows and AgeNTS), an industrial ...

A reliable SMPP implementation in Erlang Mikael Laaksonen Software failure is one of the main problems in computer systems. Especially in systems with demand for high availability, such as telecom systems. SMPP is a protocol for sending short messages between entities in the telecom network. This thesis describes the design and implementation of a highly fault tolerant and reliable SMPP server ...

We propose a hybrid plasmonic device consisting of a planar dielectric waveguide covering a gold nanostripe array fabricated on a gold film and investigate its guiding properties at telecom wavelengths. The fundamental modes of a hybrid device and their dependence on the key geometric parameters are studied. A communication length of 250 μm was achieved for both the TM and TE guided modes at te...

We demonstrate a client-server quantum key distribution (QKD) scheme. Large resources such as laser and detectors are situated at the server side, which is accessible via telecom fiber to a client requiring only an on-chip polarization rotator, which may be integrated into a handheld device. The detrimental effects of unstable fiber birefringence are overcome by employing the reference-frame-in...

This paper discusses the possibilities for broad-based IT-led economic growth in India, including increasing value-added, using better telecom links to capture more benefits domestically through offshore development for developed country firms, greater spillovers to the local economy, broadening the IT industry with production of telecom access devices, improving the functioning of the economy ...

An interpreting telephone system, or a speech translation system, will solve this problem which has been annoying human-being from the beginning of their history. The first effort was made by NEC; they demonstrated a system in Telecom'83 held in Geneva. In 1987, British Telecom Research Laboratories implemented an experimental system which was based on fixed phrase translation [Stentiford]. At ...

We present a methodology for Data Warehouse design and its application within the TELECOM ITALIA information system. The methodology is based on a conceptual representation of the Enterprise, which is exploited both in the integration phase of the Warehouse information sources and during the knowledge discovery activity on the information stored in the Warehouse. The application of the methodol...
