Question

QUESTION 13 Select the correct statement(s) regarding the channelized T-1 carrier a. channelized T-1 supports 24 DSOs; however, a T-1 frame only supports one byte of each DSO supported b. the T-1 frame rate must be 8000 frames per second c. the T-1 frame length is 193 bits long d. all statements are correct QUESTION 14 How is the Channelized T-1 rate of 1.544 Mbps determined? a. 64 frames/second * (24 DS0s/frame * 8 bits/D50) + 1 FB) b. 8000 frames/second * (24 bits/frame) + 1 FB) C. 8000 frames/second * ((24 DS0s/frame * 8 bits/D50) + 1 FB) d. 64 frames/second + ((193 bits/frame * 8 bits/DSC) + 1 FB) QUESTION 15 The Unchannelized T-1 is not divided into 24 DSOs, and therefore can support data applications that do not neatly fall into 64kbps channels. True False

Answer 1

13) Ans : d (all are correct)

A channelized T-1 carrier supports 24 DS0's and a T-1 frame only supports one byte of each DS0 supported

T-1 frame rate is 8000 frames per second and each frame is 193 bits long
