Cellular through remote control switch implies control of devices at a remote location via circuit interfaced to the remote telephone line/device by dialing specific DTMF (dual tune multi frequency) digits from a local telephone. This project Cellular through remote control switch has the following features

1. It can control multiple load (on/off/status each load)
2. It provides you feedback when the circuit is in energized state and also sends an acknowledgement indicating action with respect to the switching on of each load ....etc

Switch Architecture Guaranteeing QoS Provision and HOL Blocking Elimination

Abstract

QoS support and congestion management techniques become essential to achieve good network performance in current high-speed interconnection networks.
The most effective techniques traditionally considered for both issues, however, require too many resources for being implemented.
In this paper we propose new cost-effective switch architecture able to face the challenges of congestion management and, at the same time, to provide QoS.
The efficiency of o ....etc

Space switch fabric architecture is shown in figure. The switch consists of N incoming and N out going fiber links, with n wavelengths running on each fiber link. The switch is slotted, and the length of the slot is such that an optical packet can be transmitted and propagated from an input port to an out put optical buffer.

The switch fabric consists of three parts; optical packet encoder, space switch, and optical packet buffer. The optical packet buffer works as follows. For each incoming fiber link, three is an optical demu ....etc

It is a protocol that supports the delivery of POTS over the loop emulation service which helps to convey analog supervisory signaling states is commonly used by IWFs (interworking functions to support CCS ( Common Chanel Signalling). To avoid the signaling analog line states this protocol uses the simiar message set as the V5-PSTN (ETSI EN 300/324-1) thus covering the risk due to the variations seen in individual national implementation of analog POTS. ....etc

Membrane switch technology is a highly reliable interface solution with many advantages. The sealed nature of the overlays makes membrane switch technology an excellent front panel solution where environmental concerns are an issue. The success of any membrane switch design effort is facilitated by effective communication between the design engineers and the vendor. This design guide is intended as an outline for communicating the requirements of our customers to Nelson Nameplate Company. A mutual understanding of the technology is very benefic ....etc

1. INTRODUCTION

The growth -of existing and new services will create a large increase of traffic flow in telecommunication network in the coming years .The demand for bandwidth in a communication network increase continuously .The world wide web alone Ëœfor example require a yearly 8 fold increase in bandwidth per user . All optical networks may be the only solution to cope with such increasing bandwidth .In these network transmitter signals remain in optical format on the way from source to destination

ABSTRACT
The current fast growing internet traffic is demanding more and more network capacity everyday. As telecommunication and computer communications continue to converge, data traffic is gradually exceeding telephony traffic. This means that many of the existing connection-oriented or circuit-switched networks will need to be upgraded to support packet-switched data traffic. The concept of wavelength division multiplexing has provided us an opportunity to multiply network capacity. Current pho ....etc

BATTERY CHARGERS & BATTERY BANKS
INTRODUCTION
NEED OF BATTERY CHARGERS & BATTERY BANKS
Station battery charger is used to supply the control power to the electrical switchgear like breakers etc which need the DC supply for it’s operation and in case of failure of electrical power the control power is continued to be fed by the battery.
Battery Charger consists of
1) Float Charger
2) Boost Charger
Schemes for Battery Chargers
1) FC & FCBC scheme
