Select the correct statement regarding channelized T-1.
a. Each T-1 frame supports 24 DSOs, therefore, the frame rate must be 64 frames per second
b. Channelized and unchannelized T-1 frames must support 24 DSOS
c. Each channelized T-1 frame contains 193 bits
d. Each T-1 frame supports 24 64kbps channels. Therefore, each frame length is 24 x 64,000 = 1,536,000 bits long.

Respuesta :

Answer:

The answer is "Option c".

Explanation:

The Embedded T1 also known as channelized T1, it is a digital modulation system in which a T1 channel is split into 24 channels, in which each has the maximum connection speeds of 64,000 bits per second (Kbps) each of capable of supporting a specific application, which can run simultaneously to, but separately of, other programs on various channels, in this channelized T-1  the frame length is 193 bits long, and wrong choices can be described as follows:

  • In option a, It supports only 1 bit per second.
  • In option b, only channelized T-1 frames support 24 DSOS.
  • In option d, It length is 8000 frame per second.
