OPERATION
3-37
Reset CSU
This function resets the CSU. Resetting the CSU disrupts data transmis-
sion and creates alarm conditions for the Central Office, so use it with
care. Resetting the CSU returns you to the log-on screen and clears the
date and time, so you must set them after a reset. To reset the CSU, press
R. The CSU responds by first displaying the message WARNING:
terfering To T1 DATA to remind you of the consequences of resetting,
and then resets.
Resetting the CSU disrupts the network
transmission and creates alarm conditions for the Cen-
tral Office, so use this function with care.
Occasionally, two CSUs can be in a condition known as
a "double loop", where both are in loopback toward
the network. You can stop the loopback for a CSU if
you started it, but you cannot stop it if the Telco started
it, and there are no means to clear this condition by
sending loopback deactivation codes to both CSUs. You
can clear a double loop condition, however, by reset-
ting each CSU.
