PM6.2 Percentage availability of DCC WAN Gateway InterfaceThe Percentage Availability of the DCC WAN Gateway Interface measures the amount of time, within the Performance Measurement Period, that the DCC WAN Gateway Interface is available to DCC. Provision of the DCC WAN Gateway Interface is an activity that is performed over a period of time. The availability of the components making up the of the DCC WAN Gateway (production services) covering the associated servers, interfaces and networks shall be monitored in real-time by an infrastructure monitoring tool in accordance with Good Industry Practice. Any component unavailability will be automatically alerted to the Service Provider and where this results in an Incident an Incident shall be recorded in the DCC Service Management System; an example where component unavailability would not result in an Incident is where there is redundancy built into the infrastructure and a system 'fail over' has occurred to a back-up component. Periods of unavailability of the DCC WAN Gateway shall be recorded in the DCC Service Management System in accordance with the Incident Management Policy. The Unscheduled Downtime of the DCC WAN Gateway Interface shall be calculated as follows: the number of complete minutes where the DCC WAN Gateway Interface is unavailable to the DCC; minus the number of minutes of down time due to agreed Planned Maintenance. In respect of each Performance Measurement Period (p), the Service Level for the Performance Measure shall be calculated as follows: 
Where:
UDDWGp = the Unscheduled Downtime of the DCC WAN Gateway Interface RTp = the number of minutes within the Performance Measurement Period. The duration of the Performance Measurement Period shall be a calendar month. PM10 Notification of Planned Maintenance events within required targetThis Performance Measure measures the percentage of Planned Maintenance events, which are notified by the CSP to DCC within the required notification target. The CSP shall submit a Planned Maintenance request to DCC for approval in accordance with the time scales defined in the SEC H8.4, this time scale shall be the Target Planned Maintenance Notice. DCC shall record Planned Maintenance events in the DCC Service Management System. Planned Maintenance Notice Period shall be calculated as follows: the date the Planned Maintenance is due to begin; minus the date the Planned Maintenance request is received by DCC. Planned Maintenance Notifications on Target shall be defined as the number of Planned Maintenance requests received where the Planned Maintenance Notice Period is less than or equal to the Target Planned Maintenance Notice. In respect of each Performance Measurement Period (pq), the Service Level for the Performance Measure shall be calculated as follows: 
Where:
PNTpq = the number of Planned Maintenance Notifications on Target. PMEpq = the number of Planned Maintenance requests received by DCC. The duration of the Performance Measurement Period shall be a calendar quarter.
