set to "Enabled" on the Provisioning menu

zation (Loop Sync) and T1 alarms (if enabled) and only goes into (or out of) service if the circuit
remains synchronized and without T1 alarms during the entire measured period. These times
are also set from the Provisioning menu
A link is provided to view the Alarm History Screen. The Alarm History Screen screen is also
available by selecting the HDSL4 Main Menu opti
System responses displayed in the status fields on the Alarm History Screen are shown in
