A2G services supported O2 Telefonica in the swap out of over 1000 Tellbas 8605’s to Huawei ATN910B’s.  The ATN910B provided the customer with larger capacity, better performance and a high Quality of Service (QoS) to support the expansion of their 4g network and associated voice and data services.

To be able to integrate the ATN910’s into the live network careful planning was required to minimise disruption to legacy traffic. A2G worked with the customer to schedule the sites with the least impact whilst maximising delivery; this included working Out of Hours on high voice & data usage areas as well as distributing the minimally affected sites over a larger geographical area to ensure there was sufficient capacity in the local area to cope with the outage whilst the work was being completed.

The on the day activities included working with the customers 3rd parties to complete site and power preparations, connectivity testing and coordinating the migration of the RAN and Core technologies i.e. 2g, 3g & 4g.  Once the new ATN910B was live and all the onward traffic and services migrated we completed test calls, throughput tests and alarm output maintenance.

During the 18 months project A2G kept up a 100% success rate whilst ensure that customers delivery targets were met and exceeded
