Buttons

Click the Closedbutton to display a timeslot structure (graph) at the bottom of the pane. The structure displays attributes such as tail bits, guard bits, training sequence and data type (E field). In some cases, the E field updates to show the coding type, other times it shows the selected data type, and for some timeslots it continuously shows PN9 regardless of the data selection. After clicking this button, the button name changes to Hide Graph

Click the button to hide the structure (graph). After clicking this button, the button name changes to Show Graph.
