I. INTRODUCTION
Modern networking technologies are dramatically making major contributions to our Information Technology industry. Remote systems are acknowledged as a standout amongst the most climbing innovations in today's reality. The cheapest known stand-alone device used for communication is Intercom. Nearly all of your workplaces in addition to houses contain these kinds of convenient products. These plans are mounted for safety purposes so authenticated person easily identified. Nevertheless, very much development is necessary inside these types of technologies along with devices. Most of the exploration, pattern along with setup has been in procedure to the simulation from the automation devices.
In any communication technology, mobile devices are very common these days and their network is based on special method and systems. In Remote Intercom Access,
1.1 Project Objective
Objectives of the project are given below:
• To design a scheme for automatic door intercom system.

1.2 Design Challenges
Layout regarding a really process involves the overall performance regarding other functions.
Design of such a system requires the performance of following tasks concurrently.
• The circuit really should have a new centralized command model which can admittance just about all remote nodes which enable it by using DTMF decoding.
• In an ideal system the separation between speakers and microphones should be maximized to optimize the performance.
• It should possess some kind of intelligence built from it..
• It should generate alerts in the critical application or real time operations.

Communication can be done using the microphone and speaker and after communicating, if the owner presses 1 on the keypad, the decoder decodes the tone into a 4 bit number and main controller will unlock the door as shown in Figure 15.
If button 2 is pressed on the keypad, hook off circuit will be activated to disconnect the call as shown in Figure 16. Then the microcontrollers need to be reset by changing logic at their RST pins, to make them ready for next turn.
If button 2 is pressed on the keypad, hook off circuit will be activated to disconnect the call as shown in Figure 16.
Some of the important features for development and designing of this system are mentioned in this thesis to make the “remote intercom access” to be able to work in the desired/specific environment.
The Unistep IRP Elexol EtherIO 24 Module is a network board that enables multiple devices to connect to an Ethernet network, communicate with each other, and relay information when changes occur. The IRP module is a micro-controller, integrated with many features for interacting with devices connected on a generic local area network; this module was designed to be used in conjunction with other network devices or modules. Some of the applications for the device include industrial automation, digital input and output functions, system monitoring, remote data accessing, controlled machinery, and remote power control.
If they are in a grid or other format, button 1 is the top left one. Button 2 is the one directly to the right of that, and so on.
Captioned Telephone is a new product of Ultratec, being tested in several states. CapTel is an innovative service in which the operators repeat the words of the hearing party into an automatic speech recognition system for rapid transcription. Voice and data are carried on one line so that the hard of hearing or deaf user can monitor the speech as well as see the transcription. The CapTel phone is set up for “dial through” so that the user does not need to dial the relay service first.

Polycom's vision and strategy is to enable UC Everywhere—allowing people to communicate and collaborate anywhere on multiple devices” (Polycom Corporate, 2011).
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
The hospital needs to find a way to improve the tracking of Voice Over IP (VOIP) calls within the hospital and also wants to have a program to improve response time of medical personnel by using the GPS to locate the closes vehicle to the emergency. A design will need to be made of the Requires and Provides interfaces of two components that might be used in the VOIP system. A design of the interface is needed for two components that may be used in the vehicle discovery component to find the nearest vehicle to the incident with the Requires and Provides interfaces.
Condenser microphones are a lot more sensitive than dynamic microphones and are used for high frequency instruments like flutes, vocals etc… for this reason the group used the microphones to record all the instruments together. we positioned the microphones roughly 3 metres apart (Fig. 2). Below is a diagram illustrating the positioning of the microphones: Fig. 1 Fig. 2 Mixdown: After our recording was complete we were set the task of "mixing down" our project.

For this task the brief was to design the construction, soundproofing and acoustic treatment of a recording studio complex within a series of set constraints. The complex had to include a control room, living room, reception and bathroom, within an overall floor space of 15m x 15m. The main focus was to be on acoustic design with the use of scale drawings to make the studio clear and easy to understand. For this studio the idea was to design a space suitable for recording large ensemble groups such as orchestras and so the space was designed with this in mind when regarding the size, shape and layout of the space. Arguably two of the most important aspects when designing a studio complex are that the live and control rooms include a lot of natural light and that the communication between the artists and the studio team is free and easy. In the studio this has achieved this by creating a design similar to and inspired by ‘The Big Room’ at Real World Studios (Realworldstudios.com, 2013), where the ‘control room’ and ‘live room’ are actually all within the one space utilising the live end/dead end theory.
Teleconferencing gives a team the convenience of sharing information in real time. When meeting in this manner, team members are able to receive instant feedback. Other members can also listen to the tone and inflection of the member speaking. Telephone conferencing involves minimal cost but requires that team members be avail...
With the modern technological world today, the hotel industry has come up with room keys, which are distributed at the electronic check-in terminals, where patrons are able to see the hotel’s resident robot keep their valise. Soundproofed rooms have powered, portable bed to save space and they can activate the air conditioning by motion sensors. Besides that, the hotel industry has no longer room numbers at their room door. Patrons are able to pinpoint and open their rooms with their mobile device that uses digital recognition technology to open up their doors.

Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
In addressing the problem, the proposed research will use the case study method to examine the plan, design, and implementation of WLAN technologies at Berean. At present, the non-wireless local area network (LAN) technologies employed by Berean include 10/100BaseT Ethernet at each desktop. Ethernet ports at the desktop are switch connected to an Asynchronous Transfer Mode (ATM) T1 backbone. Berean¡¦s one remote facility connects to the network using switched Frame Relay services along with Internet Virtual Private Network (VPN) connections.
Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened.
