3. Force Majeure

4. Outage Calculations

To calculate Service Outage, TELAIR uses a combination of methods, including analyzing logs from both Voice Services event monitoring systems and the actual affected infrastructure components. TELAIR will match these findings with client reports to determine the actual timeframe. Any loss of Service Availability less than five(5) minutes in duration will not be included in the calculation of Service Availability.

5. Outage Credit

If TELAIR Availability for Customer in any monthly billing cycle falls below the level set forth above Section 4, TELAIR will issue a credit (“Service Outage Credit”). The credits will be verified for validity and will be subject to other conditions herein. The Service Outage Credit will be calculated at rates specified within the schedule included below.

Service Outage Credit Request and Payment Procedures To request a Service Outage Credit, (a) Customer Account must be in good standing with TELAIR (i.e., current on all payments) at the time of the request, (b) Customer must open a technical support ticket via email at support@telair.net reporting an apparent Service interruption within forty eight (48) hours of the event requesting a Service Outage Credit. Service Outage Credit requests must include Customer Account name or Account number and the dates and specific times for which Customer is requesting Service Outage Credits. TELAIR will compare information provided by Customer to the data referenced in Section 4 above. TELAIR will calculate the Service Outage Credit based on the type of particular service for which the Service was not available, the service fees for the particular Service and the percentage of overall individual Service affected.
Limits on Service Outage Credit & Sole and Exclusive Remedies Subject to Customer’s valid submission of a Service Outage Credit request and other conditions herein, if a reported Service Availability under Customer Account for any calendar month is below 99.996%, TELAIR will issue a credit in accordance with the following schedule:

Service Availability (per calendar-year)	Credit amount as a % of monthly fee of affected service
99.0% to 99.996%	5% of monthly fee credited
98.0% to 98.99%	10% of monthly fee credited
95.0% to 97.99%	20% of monthly fee credited
90.0% to 94.9%	40% of monthly fee credited
89.9% or below	60% of monthly fee credited

Total Service Outage Credit The Total Service Outage Credit due to Customer for any service affected may not exceed sixty percent (60%) of the monthly service fees charged for use of the service during the month for which the Service Outage Credit is to be issued, unless the amount to be credited is less than ten dollars ($10.00) in which case the credit amount will be ten dollars ($10.00). Only one (1) Service Outage Credit is available in any given calendar month. Credits are applicable only toward use of the Service and are not convertible into cash or any type of refund.

6. Service Commitment

TELAIR is to provide customers reliable and dependable service and is committing to the following service levels

Mean Opinion Score (MOS) Commitment MOS is a measure (score) of the audio fidelity, or clarity, of a voice call. It is a statistical measurement that predicts how the average user would perceive the clarity of each call. TELAIR is committed that the Voice Network performance will not drop below 4.0 where MOS is calculated using the standards-based E-model (ITU-T G.107). Performance is measured by periodically collecting data across the Voice Network, from which a monthly average is derived.
Jitter Commitment Also known as delay variation, jitter is defined as the variation or difference in the end-to-end delay between received packets of an IP or packet stream. TELAIR is committed that monthly jitter performance within the Voice Network will not exceed 20.0 millisecond. Performance is measured by periodically collecting data across the Voice Network, from which a monthly average is derived.
