  • True
    Set Fault monitoring level on the TDM and DS1 Ports to match the value specified on this ISDN PRI DS1.
  • False
    Leave Fault monitoring level unchanged on the TDM and DS1 Ports.

  • Normal (level 10)
    Alarms for this ISDN PRI DS1 appear in the EMS and are sent to SNMP alarm notification destinations as usual.
  • Suppress alarms (level 5)
    Alarms for this ISDN PRI DS1 do not appear in the EMS and are not sent to SNMP alarm notification destinations.
