Configuring the CSU

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:
