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:
