In mode 4 x V.24 asynchronous with controls, the SM_V24E supports four channels, each with eight wires.
The following table lists the pin assignment for a typical connector when the SM_V24E is in 4 x V.24
asynchronous with controls mode. This table also lists the color of the wire connected to the corresponding
pin in the cables offered by ECI for connecting the tributary connector and a distribution frame.
