If you have selected an American switch type, you can edit CSU properties for the board. DS1 is the long haul configuration used for connecting the board to a T1/PRI line. If the board is connected directly to the line in a standard DS1 configuration, the board’s internal CSU must be activated for each PRI port. (For more information about line connections, see T1/PRI Line on page 27.)
The following table describes DS1 options that can be edited:
