15. Display a list of all the sites that have alarms enabled. Command(s) used: at BSC disp_act_alarm all

16. Now that we are registered to receive alarms at the local TTY we can verify that the Internal Alarm Services (IAS) feature is operating. Power off a CTU at your site. And observe the response at the screen Note: As the IAS is a polling process, this may mean that there is a short delay after the removal of a link before the alarm is generated. Now display the active alarms list at your site, ensure that it contains the alarms we have just generated. Command(s) used: disp_act_alarm XX Restore power to the CTU, and ensure that it comes back into service. 17.
