Exhibit A3 — Key Performance Indicator and Quality of Service

SMS Hosted Managed Service

Key Performance Indicator

The “Key Performance Indicator” for the service is the Service Availability Level set out below. These Service Level commitments are contingent upon the fulfillment by Customer of its responsibilities under this Schedule.

Service Availability Level (%)		Effective Date
99.99%		From Customer Acceptance.

Table A3.1

The Service Availability Level, as calculated using the formulas shown below in Table A3.2, shall be measured over the period of each calendar month, calculated as set forth below; provided that Service Availability shall be measured on a prorated basis for the first and last months that this Schedule is in effect:

Planned Service Availability		=		Available Time in Month – minus Scheduled Downtime
Actual Service Availability		=		Planned Service Availability – minus Unscheduled Downtime
Service Availability Level (%)		=		Actual Service Availability divided by Planned Service Availability in that month

Table A3.2

For any System Outage, the “Unscheduled Downtime” period begins when a System Outage pertaining to the System as described below is reported to Ericsson’s Technical Support. The “Unscheduled Downtime” period ends when the System is remedied.

“System Outage” means any event that precludes more than 10% of SMS attempts from processing during the event.
