Chapter 18 - Communication

Question 1

911/Enhanced 911

Answer 1

A set of three numbers that automatically sends the call to the emergency dispatch center.
Enhanced 911 gives the dispatcher the ability to determine the caller’s location by roughing the call through several CAD systems.

Question 2

Band

Answer 2

A range of radio frequencies.

Question 3

Computer-Aided Dispatching (CAD)

Answer 3

A computer-aided system that automates dispatching by enhanced data collection, rapid recall of information, dispatch mapping, as well as unit tracking and the ability to track and dispatch resources.

Question 4

Communication

Answer 4

The exchange of information between two or more individuals.

Question 5

Dispatch

Answer 5

A central location that revives information and collects, disseminates, and transmits the information to the proper resources

Question 6

Duplex

Answer 6

A radio system that allows transmitting and receiving at the same time through two different frequencies

Question 7

Federal Communications Commission (FCC)

Answer 7

An independent US government agency, directly responsible to congress, established by the Communication Act of 1934; It regulates interstate and inter nation communication by radio, television, wire, satellite, and cable. The FCC’s jurisdiction covers the 50 states, the District of Columbia, and US possessions.

Question 8

Half Duplex

Answer 8

A radio system that uses two frequencies: one to transmit and one to receive; however, like a simplex system only one per on at a time can transmit. This system is commonly used in conduction with repeaters.

Question 9

Interoperability

Answer 9

Describes a radio system that can use components of several different systems; it can use specialized equipment to connect several different radio systems and components together and have them communicate with each other.

Question 10

Mobile Radio

Answer 10

A radio installed in an emergency vehicle. A mobile radio usually transmits by hight wattage than a portable radio. Transmits at 50-100 Watts.

Question 11

Multiplex

Answer 11

A system that allows the crew to transmit voice and data at the same time, enabling the crew to call in a patient report while transmitting an ECG strip to the hospital at the same time

Question 12

Portable Radio

Answer 12

Also know as a Walkie-Talkie. These radios are carried by emergency personnel and have a lower wattage output than the mobile or base unit. To use theses portable radios with a hight watt output, the units can be connected through a repeater system to increase their output, which increase range. Transmits at 1-5 Watts.

Question 13

Public Safety Answering Point (PSAP)

Answer 13

A dispatch center that is set up to receive and dispatch 911 calls

Question 14

Radio Frequency

Answer 14

Radio frequencies are channels that allow communication from one specific user to another. For simple communication, both users must be on the same frequency or channel

Question 15

Repeater

Answer 15

A system that reeves transmissions from a low-wattage radio and rebroadcasts the signal at a higher wattage to the dispatch center.

Question 16

Simplex

Answer 16

A system that allows only one-at-a-time communication. The transmission cannot be interrupted; both operators use the same frequency.

Question 17

Telematic

Answer 17

A system setup as mayday call reporting, such as On-Star and Tele-Aid. This system can send information from an automobile that has been involved in a accident directly to an emergency dispatch center with the exact location and the amount of damage that may have occurred.

Question 18

Trunking System

Answer 18

A system that used multiple repeaters (five or more) so that a computer can search for an open channel to transmit by.
