Q
Telephone
traditional landline telephone system, known as ______, handles signaling and audio information on the same twisted pair of insulated wiere: the telephone line.
A
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.
5
Q
Process of POTS
A
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.

10
Q
How Telephone Works?
A
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.
11
Q

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.
43
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.

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.

is a bar, or pole pivoted to allow the boom to block vehicular or pedestrian access through a controlled point.[1] Typically the tip of a boom gate rises in a vertical arc to a near vertical position. Boom gates are often counterweighted, so the pole is easily tipped. Boom gates are often paired either end to end, or offset appropriately to block traffic in both directions.

is a control device that detects, reports and acts on hazardous fires in buildings.
When a device is connected to the panel is activated (eg. smoke detectors, heat detectors, sprinkler flow switches or alarm is set off automatically), this compenent will directly call the fire deparment via a so called **Alarm Transportation System**

Alarm Devices
An alarm device taht automatically detects the presence of smoke is called \_\_\_\_.
A device that senses the presence of a smoke in a building and warns the occupants, enabling them to escape a fire before succumbing to smoke inhalation or burns.
Smoke Sensor
156
Two basic types of Smoke detectors are current manufacture for residential use:
uses an optical beam to search for smoke. When smoke particles cloud the beam, a photoelectric cell senses the decrease in light intensity and triggers an alarm.
Photoelectric Smoke Detector

Two types of Smoke Detectors
is quicker sensing flaming fires that produce little smoke. It employs a radioactive material to ionize the air in a sensing chamber, the presence of smoke affects the flow of the ions between a pair of electrodes which triggers the alarm.
