Telecommunication systems allow transmission of information over distances. A basic system includes a transmitter that converts information to signals, a transmission medium like free space to carry the signals, and a receiver to convert signals back to information. Wired telephone connections involve telephone lines connecting to exchanges, distribution points, and homes. Wireless systems use base stations connected to exchanges to transmit radio signals to customer premises equipment like phones. Private branch exchange systems allow internal calling between phone sets and public switched telephone network access, while digital subscriber line systems use existing copper phone lines more efficiently to provide both phone and high-speed internet services.

Technical report on Transistor Based Intercom SystemSourav Rakshit
The intercom circuit will let us talk with another person in a distant room. The kit will be in one room and speaker will be in other room. When a person speaks, his voice signals will be changed into electrical signal by a condenser microphone and then the electrical signals generated will be transmitted through the circuit. The electrical signals at the other end will be converted into analog or voice signals by the speaker used and hence the person at the other end can hear the message. The unit having all components is called master unit and the unit having only the speaker is called slave unit.
In data communication,
Transmission media is a pathway that carries the information from sender to receiver.
We use different types of cables or waves to transmit data.
Data is transmitted normally through electrical or electromagnetic signals.
Synchronous optical networking (SONET) is a standardized digital communication protocol that is used to transmit a large volume of data over relatively long distances using a fiber optic medium. With SONET, multiple digital data streams are transferred at the same time over optical fiber using LEDs and laser beams.

Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

Cracking the Workplace Discipline Code Main.pptxWorkforce Group
Cultivating and maintaining discipline within teams is a critical differentiator for successful organisations.
Forward-thinking leaders and business managers understand the impact that discipline has on organisational success. A disciplined workforce operates with clarity, focus, and a shared understanding of expectations, ultimately driving better results, optimising productivity, and facilitating seamless collaboration.
Although discipline is not a one-size-fits-all approach, it can help create a work environment that encourages personal growth and accountability rather than solely relying on punitive measures.
In this deck, you will learn the significance of workplace discipline for organisational success. You’ll also learn
• Four (4) workplace discipline methods you should consider
• The best and most practical approach to implementing workplace discipline.
• Three (3) key tips to maintain a disciplined workplace.

2. Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags,
6. A basic telecommunication system consists of three primary units that are always present in some form A transmitter that takes information and converts it to a signal. A transmission medium, also called the "physical channel" that carries the signal. An example of this is the "free space channel". A receiver that takes the signal from the channel and converts it back into usable information.
7.
8. Telecom The network used to connect the telephone to telephone exchange. The connection between telephone and exchange can be two copper wire or wave. If copper wires are used it is called wired connection. This connection also can be provided by a radio wave. It is called a wireless
10. Stages involved to a wired connection Telephone exchange MDF Cabinet DP Telephone
11. The function of telephone exchange When a telephone dials a number it is received by the telephone exchange and analyses the number and connect to the relevant telephone via the remote exchange. For the calls received from the remote exchange the originated telephone exchange checks whether the relevant telephone is free or busy. If the telephone is busy the busy tone is sent to the other exchange. If the telephone is not busy the ring back tone is sent to the other exchange.
12. Main Distribution Frame (MDF) MDF is the interface between telephone exchange and telephone cables. At the time of installation of exchange all telephone channels are terminated at the MDF
13. The multi pair telephone cables are terminates of the side. When a new connection is given the exchange side relevant point and cable side relevant point are connected by using another small. This small cable is called a jumper wire.
14. Cabinet MDF to cabinet cable is called primary cable Cabinet to DP cable is called secondary cable Primary cable to secondary cable jumpering is done at the cabinet.
15. Distribution Point A 10 pair or 5 pair cable is laid from cabinet to distribution point (DP). That means there are 10 loops or 5 loops in a DP. When a new connection is provided a pair of cable is drawn from DP to home
16. The works to be done to provide a telephone new connection DP to house cabling ( over head cabling) Jumpering at MDF The telephone exchange identifies a free line. Allocate a telephone number from the exchange and program it in the exchange
17. Base station Telephone is connected to Base Station by using a radio wave. The Base Station is connected to telephone exchange by using copper or fibre optic
23. Telephone cable incoming size Categories 1 More than 5 storey and the area of floor exceeding incoming 650 m2. Incoming size cable exceeding of 50 pairs. Categories 2 Less than 5 storey and floor area less than 650 m2. Incoming size less than 50 pairs of cables. Categories 3 Detached houses or bungalows for residential. 1 pairs of cable size.
24. Characteristic for domestic telecommunication wiring The grey colored cable should be used for domestic telecommunication system wiring. The cable should be protected by a conduit pipe The cable should not be exposed to the weather The wiring cannot run on the ceiling The wiring should be done in horizontal way or vertical way only Be precise on cable usage
25. Private Branch Exchange (PBX) System This diagram shows a private branch exchange (PBX) system. This diagram shows a PBX with telephone sets, voice mail system, and trunk connections to PSTN. The PBX switch calls between telephone sets and also provides them switched access to the PSTN. The voice mail depends on the PBX to switch all calls needing access to it along with the appropriate information to process the call.

27. Digital Subscriber Line (DSL) System This figure shows a basic DSL system. This diagram shows that the key to DSL technologies is a more efficient use of the 1 MHz of bandwidth available on a single pair of copper telephone lines. A DSL system consists of compatible modems on each end of the local loop. For some systems, the DSL system allows for multiple types of transmission on a single copper pair. This includes analog or ISDN telephone (e.g., POTS) and digital communications (ADSL or VDSL). This diagram shows that there are basic trade offs for DSL systems. Generally, the longer the distance of the copper line, the lower the data rate. Distances of less than 1,000 feet can achieve data rates of over 50 Mbps.
