Usage
Indicate the direction of the echo that is being cancelled.
Usage
Enter y to allow echo cancellation.
Usage
Enter other if no channel service unit is attached to the
DS1 facility or if the CSU is an external unit. No options
are available on page 2 for administering an external
CSU.
Enter integrated if a 120A CSU module is attached to
the DS1 board. This integrated channel service unit
(ICSU) can accept software-administrable option
downlinks (that is, it can respond to test codes from
technician's equipment and report its status). When you
enter integrated, fields for administering options on the
ICSU appear on page 2 of the DS1 Circuit Pack screen.
