SLA Scope

Software Defect Resolution takes long time. We provide work-around in live network for critical defects.

Nash Support – Key Differentiators• Quick technical alignment with customer requirements by deploying right

resources• We ensure the least turnaround time and offer operational flexibilities• Our focus is on providing high quality technical engineering resources to

exceed the customer expectations with minimum ramp-up time• Well trained and experienced staff used to work with different technologies

and software tools • Our engineers can implement methods and practices learned through

experience gained by working in multi-vendor environment

Network Analysis Platform Overview

• Easy but complete Network Performance analysis• Identify problems in less time• Correlate various data from different sources

• Performance Measurements / KPIs• Alarm data• Network topology changes• NE log files

• Scales with your network• Supports various vendors and technologies

Network Tuning – High Traffic Events• Anticipated high traffic events - generic events like different festivals, or Christmas

and New Year’s Eve which increase the traffic across the network:– Forecast and plan for additional hardware cards to increase the capacity of the network– Optimize configuration parameters and features to increase capacity (pre-discussed and agreed with

Operator)– Constantly monitor the threshold limits

• Non-anticipated high traffic events such as natural disaster that may increase the traffic in a certain region or across the network:– Support the high traffic NEs by adding extra hardware cards– Optimize configuration parameters and features to increase capacity (pre-discussed and agreed with

Operator)– Constantly monitor the threshold limits

Level of support Nash Technologies are doing for AT&T

Level 2/3 support

Services and tasks we offer• Analysis and solving of problem tickets• KPI analysis and trending• Analysis and trending of field log files and proactive identification of system or

product issues• Analysis of network and UE traces to debug complex IOT issues• On-site support for first field application of new UMTS network features or special

high traffic/high attention events• Product and debug training for market/MNO teams• Specification and implementations of UMTS debug capabilities to speed-up

analysis of critical field product issues• Mitigation of critical field issues by implementation of mitigation scripts• 24/7/365 telephone hotline for critical system outage situations


11July, 2015

Solve problem reports• Provide advanced technical support for problem reports

– Tickets can be originated “in House” by performance teams, network supervision teams – or Tickets originated by subscribers

• We cover full range of:– Log file collection– Arrange with local teams for drive tests– Communicate with the network vendor if necessary to escalate the issue

• Utilize experience from other network providers• Apply and verify corrective actions• Act according and within specified SLA times

– By dynamically assigning necessary resources from our highly skilled people pool


12July, 2015

Your Benefit: Highly skilled team scalable to urgency/complexity of the issue allowing fast turn around times leading to high user satisfaction.

KPI analysis / trending• Correlate PM/KPI data with events

from alarms/reset logs• Look at KPI trends of complete

network to identify high runner issues

• Find high runner NodeBs• Utilize network vendor

independent tools• Verify implementation of

corrective actions• Provide own servers for PM data

storage and event/alarm logs


13July, 2015

Your Benefit: Fast analysis and correlation of network events with KPI/PM data. Save money instead of purchasing similar analysis platforms from 3rd party.

Proactive field log collection• Collect logs from all NodeBs periodically• Create Reports for board resets, network

utilization and more• Have logs readily available for problem reports• Analyze impact of SW Upgrades and other

changes• History of network topology to identify if HW

changes cause issues• Utilize own developed tools and framework

instead of purchasing them on open market


14July, 2015

Your Benefit: Improved network reliability and identification of issues prior to user complains.

Debug complex IOT issues• Analyse issues from network as well

as• from UE perspective using tools like:

– Vendor provided tools (xCDM)– Own developed call trace analyzer– 3rd Party tools (TEMS/QXDM)

• Work closely with network as well as UE/Chipset vendor


15July, 2015

Your Benefit: Utilize advanced tools specifically developed for the job. Benefit from synergies in experience from other network providers.

Product and debug training• Train market/MNO teams for new

3GPP evolutions• Provide insight into product debug

capabilities• Work with market teams on

best practice for parameter settings (golden parameters)


16July, 2015

Your Benefit: Get your staff up to speed on new features and profit from our strong debug knowledge, making you vendor independent and save money.

Mitigation of field issues

• Workaround for critical issues• Allows to bridge the time till fix is rolled

out with new SW load– Avoid fallback of SW– Still have access to feature in new load

• Execute low level commands on all sites– Clear hanging resources– Reinitialize parameters


17July, 2015

Your Benefit: No need to wait for SW fixes from vendor. Allows continued rollout to stick to original schedules and have features available on time.

Our testing facilities in Nürnberg and Stuttgart consist of two fully equipped Test Labs with live mobile network simulation of 2G / 3G / 4G as well as TDM, NGN, and IMS network elements and protocols.

Cooperation models Standard Way of Working:

The operator sends us the bundle of error-tickets for the complex network issues and we work on solutions, in accordance with SLA times, or

Alternative Option A)

In cooperation with the operator’s preferred L1 support provider we can add a multi-vendor L2 support to their portfolio, or

Alternative Option B)

In cooperation with the operator’s preferred telecom vendor we can add to their portfolio a multi-vendor L2 support for the equipment from the other vendors, or

When Business Is Established

We have a full scope of the multi-vendor managed support services agreement with the telecom operator
