Chapter 10 - Wired Telecom Technologies

Question 1

Wired Telecom technologies

Answer 1

Also known as wireline, these technologies are all based on copper or fiber optic cabling.

Question 2

DS-1

Answer 2

Digital Signal 1 is a multiplexed telecommunications protocol family used in North America, Korea and Japan.

The line rate of a DS-1 circuit is 1.544 Mbits/s.

When used to carry voice traffic, a DS-1 carries 24 voice channels at 64 Kbits/s each.

Question 3

SONET

Answer 3

Synchronous Optical Networking is the prevalent standard in North America for transporting voice an data over optical fiber.

SONET is a phisical layer technology that that can be used to encapsulate network technologies such as ATM and TCP/IP.

160Gbit/s

Question 4

MPLS

Answer 4

Multiprotocol Label Switching is a packet-switched technology that is used for both voice and data and can be used to carry IP, ATM, SONET and Ethernet frames

Question 5

DSL

Answer 5

Digital Subscriber Line is a group of technologies used to deliver digital data services over telephone wires.

Question 6

ATM

Answer 6

Asynchronous Transfer Mode is a packet-switching network protocol that uses fixed-size packet called a cell to transport data. It is a data-link layer protocol that is transported on various physical-layer media.

Question 7

Wireless Telecom Technologies

Answer 7

Wireless telecom technologies refer to the various methods and technologies used to transmit voice, data, and multimedia over wireless networks. These technologies enable communication without the need for physical cables or wires and have become an integral part of modern telecommunications.

Question 8

CMDA2000

Answer 8

CDMA2000 (code division multiple access) is a mobile radio technology
used to transmit voice and data between subscriber devices (usually cellular phone handsets and PCMCIA cellular modems) and network providers’ base stations, for purposes of voice and data communications.

Question 9

GPRS

Answer 9

General Packet Radio Service (GPRS) is a data-centric mobile radio technology used in the Global System for Mobile Communications (GSM) network. GPRS devices include mobile handsets and PCMCIA-based modems for PCs

Question 10

EDGE

Answer 10

Enhanced Data rates for GSM Evolution (EDGE) and Enhanced GPRS (EGPRS) are the successors to GPRS and provide bandwidths up to 1 Mbit/s.

Question 11

LTE

Answer 11

Long Term Evolution (LTE) is a high-speed wireless data communication technology
that is based on GSM and UMTS technologies

Question 12

UMTS

Answer 12

Universal Mobile Telecommunications System (UMTS) is another data-centric mobile radio technology found in wireless handsets and PC card modems. UMTS is usually transported over W-CDMA networks and supports up to 14 Mbit/s throughput

Question 13

WiMAX

Answer 13

Worldwide Interoperability for Microwave Access (WiMAX) is a data-centric radio technology for point-to-point and mobile access. Based on IEEE 802.16, WiMAX is a
wireless competitor to DSL and cable modems but also competes with the strictly mobile data standards such as CDMA2000, GPRS, EDGE, LTE, and UMTS.
