Here follows a description of the Services to be provided by Airspan:

1.1 Technical Support Services

Technical Support Services, the foundation of the Airspan Support Services portfolio, provides remote support for issues associated with the operation and maintenance of Airspan products. Technical Support Services includes two levels of service:

·	Remote Technical Assistance

·	Emergency Recovery

Remote Technical Assistance provides assistance to address network issues that are not classified as emergency priority. Airspan will register and manage requests for Technical Assistance during normal business days and business hours observed by Airspan in the region where the service is being performed.

Note: Airspan classifies Technical Assistance case priorities as Business Critical, Major, and Minor. Please refer to “1.1.6 Technical Support Case Priority Classifications and Examples.”

Emergency Recovery provides assistance to address emergency network issues. Airspan will register and manage requests for Emergency Recovery 24 hours per day, seven days per week including holidays observed by Airspan in the region where the service is being performed.

Exhibit A - Description of The Technical Assistance Support Services

Agreement for the Provision of Technical Assistance Support Services for FWA Equipment (December 2004)

To provide Remote Technical Assistance and Emergency Recovery, Airspan technicians and engineers will provide support primarily by remote means. In a collaborative effort with Axtel’s technical staff, these personnel will attempt to diagnose and resolve issues related to the hardware, software, and/or documentation supplied by Airspan as explained in this service description.

For both Remote Technical Assistance and Emergency Recovery, where telephone support, remote diagnosis, and all other means of restoring product operation have failed, Airspan, upon Axtel’s request, and if Airspan determines that on-site support is necessary and appropriate, will dispatch a trained and qualified technical expert to Axtel’s premises to facilitate further diagnosis.

Notwithstanding Airspan’ determination that on-site support is not necessary, Axtel will nevertheless have the right to require on site support from Airspan, provided that such on site support required by Axtel shall be at Axtel’s cost unless it is agreed that it was necessary for such support to be provided on site.

1.1.1 Technical Assistance Deliverables

Resolution activities, based on typical cases, may include:

·	Remote Troubleshooting problems using diagnostic utilities

·	Providing advice on how to detect and resolve hardware and network-related problems

·	Advising on issues requiring hardware replacement

·	Diagnosing issues related to Airspan products interfacing with non-Airspan products

Note: Airspan will resolve the issue to the point of demonstrating that the problem is attributable to the non-Airspan products and, under the coordination of Axtel, a Airspan technician can be available to discuss the fault issue with the appropriate vendor.

·	Analyzing trace/log/dump/Operational Measurement (OM) information

·	Remote telephone and/or email support to Airspan Second Level support (NTS) in troubleshooting, diagnosing and correcting failures by Airspan hardware and/or software to function as per the relevant Airspan product specifications in Axtel’s network.

·	Providing regular, on-going updates on case progress using an agreed-upon medium

The Emergency Recovery team will be in constant contact with Axtel throughout this case resolution activity, if requested.

Note: Please refer to “2.2 Call Center Access for Technical Support.”

Following service restoration, the E1/E2 case will be closed in agreement with Axtel and a follow-up case (Major for E1 and Minor for E2) can be opened, if further investigation or problem resolution activity is needed. Furthermore, Airspan may, where applicable, conduct a root-cause analysis of the emergency incident, which may be made available to Axtel.

Status	Description	Airspan Clock
Newly Opened	This status is the default. It signifies that no work has been done on the case.	Start
WIP Level 1	This status is used when a NTS Engineer is actively working on the Case.	Not Stopped
WIP Level 2	This status is used when a Second Level Support Engineer is actively working a case * Second Level Support: Software Support, Product Support.	Not Stopped
Escalated To Design	This status is used when a Design Engineer is actively working on the case	Not Stopped
Answer From Design	Design Engineer has concluded its investigation and has replied back to the NTS Engineer	Not Stopped
With A Customer	During the course of conducting their research, the NTS Engineer may need additional information or activity from the Customer. The "With a Customer” status is assigned when the NTS Engineer is waiting on a Customer response in order to continue investigation	Stopped

Exhibit A - Description of The Technical Assistance Support Services

Agreement for the Provision of Technical Assistance Support Services for FWA Equipment (December 2004)

Status	Description	Airspan Clock
Interim Solution	If a temporary solution is provided that eliminates the customers pain until a permanent solution can be delivered, RQMS requirements allow the case to be set to an “IS” status during this window of time if approved by the Customer. In calculating case age, this interval will be discounted if the permanent fix was delivered on the negotiated commitment date. If the permanent fix does not resolve the reported problem, case status shall be changed to Work in Progress (Level 1 or 2). If the case is returned to a Work in Progress (Level 1 or 2) status after using the IS, the IS time period will be added to the RQMS age of the case.	Stopped
Future Deliverable	Customer agrees to live with the problem condition and that the fix will be delivered as part of a future Airspan product release (software release, maintenance release, documentation release or hardware revision. Requirements to use this status include Customer consent; fix identification, and delivery commitment. This status code does not add time to the RQMS age of the case unless the solution fails and the case is moved back to Work in Progress (Level 1 or 2) status. If the case is returned to a Work in Progress (Level 1 or 2) status after using the FD, the FD time period will be added to the RQMS age of the case.	Stopped
Solution Delivered	Solution Delivered or available for testing and verification. If the delivered solution does not resolve the reported problem, the status will be changed to Work in Progress (Level 1 or 2). If the case is returned to a Work in Progress (Level 1 or 2) status after using the SD status, the SD time period will be added to the RQMS age of the case.	Stopped
Pending OEM Vendor	The case has been handed over to an OEM Vendor for resolution	Not Stopped
