Telephone
Who developed the telephone?
Alexander Graham Bell
Telephone
the device operates princially by converting sound waves to electrical signals (transmitter), and electrical signals to sound waves(receiver).
Telephone has 3 main parts, what are these?
- Speaker (the upper portion made out of plastic or metal, “receiver”
- Microphone (transmitter)(the lower portion (converts sound waves to electrical signals that goes to the other telephone and becomes a soundwave)
- Hook Switch
Telephone
contains a device called _____ to block the sound of your voice from reaching your ear. Modern telephone includes a ___ so it can ring and a touch-tone keypad and frequency generator.
duplex coil
bell
Telephone
traditional landline telephone system, known as ______, handles signaling and audio information on the same twisted pair of insulated wiere: the telephone line.
Plain Old Telephone Service (POTS)
Plain Old Telephone Service (POTS) refers to the basic voice service traditionally transmitted over the copper wire network. The sound waves of a caller’s voice are converted by the telephone handset into electrical signals that travel over the network. The copper network is prone to interference, and the signal may weaken over distance, thus requiring amplification along the way.
Process of POTS
from telephone to the drop cable,
from the drop cable to the Transmitter Terminal
from the terminal to the Central Phone Office Co.
from Central Phone Office Co. to another Central Phoone Office Co (this happens when the receiver of the call if too far from the caller)
from the final Central Phone Office Co. to the Receiver Terminal
from Terminal to Telephone where Call may be received.
what is a Handset?
A mobile Phone
Telephone
The signaling equipment consists of a bell, beeper, light or other deviceo alert users to incoming calls. A ____ is preferred as it is more effective at rejecting electromagnetic interference (EMI) and crosstalk than an ____.

How Telephone Works?
When a person speaks into a telephone, the sound waves created by his voice enter the mouthpiece. An electric current carries the sound to the telephone of the person he is talking to. A telephone has two main parts: (1) the transmitter and (2) the receiver.
The Transmitter of a telephone serves as a sensitive “electric ear.” It lies behind the mouthpiece of the phone. Like the human ear, the transmitter has an 14 eardrum.” The eardrum of the telephone is a thin, round metal disk called a diaphragm. When a person talks into the telephone, the sound waves strike the diaphragm and make it vibrate. The diaphragm vibrates at various speeds, depending on the variations in air pressure caused by the varying tones of the speaker’s voice.
Telephone: How dial tone works
Circuitry has low resitance (less than ____ ohms) which causes DC (48volts, nominal) from the telephone exchange to flow through the line. The ______ detects this DC, attaches a digit receiver circuit to the line, and sends a dial to the indicate readiness.
300 ohms
Exchange
Telephone
Bottons are connected to a tone generator circuit that produces DTMF tones which end up at a circuit at the exchange. A _____ telephone employs pulse dialing, sending electrical pulses corresponding to the telephone number to the exchange.
rotary dial
DTMF
(dual tone multi frequency) is the signal to the phone company that you generate when you press an ordinary telephone’s touch keys. In the United States and perhaps elsewhere, it’s known as “Touchtone” phone (formerly a registered trademark of AT&T). DTMF has generally replaced loop disconnect (“pulse”) dialling.

The ____ is where the cable system receives programming from various sources (eg. ABS CBN), assigns the programming to channels and retransmits it onto cables.
HEad End
How CATV processing works
At the regional headend, the TV channels are sent multiplexed on a light beam which travels through optical fiber trunklines, which fan out from distribution hubs to optical nodes in local communities. Here the light signal from the fiber is translated to a radio frequency electrical signal, which is distributed through coaxial cable to individual subscriber homes.
1989: Using MPEG compression, CATV systems installed today can transmit up to 10 channels of video in the 6MHz bandwidth of a single analog channel, when combined with a 550 MHZ overall bandwidth, this allows you to have a nearly 1000 channels of video system.

Intelligent Building Control (IBC)
Difference between Building Automation System and INtelligent Building Control
MARCH 23, 2018
The emergence of intelligent buildings and data-driven facilities management practices has begun to create some confusion for customers trying to understand how to make investments in their facilities and the systems that help operate them. Many of them are asking the question I already have a building automation system, why do I need an intelligent building? What is the difference?
The confusion surrounding these two concepts is understandable given the number of solutions available on the market today, but it is a misconception that a facility with a traditional building automation system (BAS) or building management system (BMS) can provide the same functionality as an intelligent building. Both an intelligent building and a building with a traditional BAS use software and programming to control the function of facility assets like HVAC, lighting, and security infrastructure, but the capabilities beyond this core function and the value delivered to the owner is different between intelligent buildings and building automation systems.
To assist with articulating the differences between these two concepts, let’s first look at the definition:
Automation (n) – automatically controlled operation of an apparatus, process, or system by mechanical or electronic devices that take the place of human labor.
Intelligence (n) – (1): the ability to learn or understand or to deal with new or trying situations (2): the ability to apply knowledge to manipulate one’s environment or to think abstractly as measured by objective criteria (such as tests).
Building automation systems help a facility owner save energy and optimize performance through things like scheduling, controlling output based on occupancy, and more. However, the capabilities of a traditional BAS stop there.
The major difference between a BAS and an intelligent building is the ability for an intelligent building to analyze data from multiple sources. The control of your facility assets becomes ‘intelligent’ through the facility’s ability to learn from that data and change operations accordingly. For owners with a robust BAS in their facilities today, moving to an intelligent building is the next step forward.
