How does T-1 multiplexing work??
What will be an ideal response?
In T-1 multiplexing, the frames of the T-1 multiplexor's output stream are divided into 24 separate digitized voice/data channels of 64 kbps each. Users who wish to use all 24 channels are using a full T-1, while other users who need to use only part of the 24 channels may request a fractional T-1. The T-1 multiplexed stream is a continuous repetition of frames. Each frame consists of 1 byte from each of the 24 channels (users) plus 1 synchronization bit. Thus, data from the first user is followed by the data from the second user, and so on, until data from the 24th user is once again followed by data from the first user. If one of the 24 input sources has no data to transmit, the space within the frame is still
allocated to that input source The input data from a maximum of 24 devices is assigned to fixedintervals. Each device can transmit only during that fixed interval. If a device has no significant data to transmit, the time slot is still assigned to that device, and data such as blanks or zeros are transmitted.?

Which of the statements a, b and c is true?
a. Pane is the base class for layout panes. This can be used to position nodes at fixed locations—known as absolute positioning. b. StackPane Places nodes in a stack. Each new node is stacked atop the previous node. You might use this to place text on top of im-ages, for example. c. TilePane A horizontal or vertical grid of equally sized tiles. Nodes that are tiled horizontally wrap at the TilePane’s width. Nodes that are tiled vertically wrap at the TilePane’s height. d. All of these statements are true.
