ATM to Ethernet: Mobile Backhaul Migration Case Study

ATM to Ethernet: Mobile Backhaul Migration



Requirement
The client is a mid-Eastern telecommunications provider who provides ATM services to third party base stations and their own base stations. The client’s end customer was using ATM interface for leased lines for voice, data and video. The ATM network was being switched off, but the end customers did not want to upgrade as they have made significant investments in equipment and processes that depend on ATM and specific features the service offers. They also felt it would be too difficult and disruptive for them to move to alternate services.

Virtual Access Solution
Previously, the radio base station received mobile phone traffic and sent this to a central site over ATM or other switching protocols. Using the GW8000 Series router and Activator, the traffic at the radio base station is converted to Ethernet and is transported in IP over Ethernet. The solution enabled the client to maintain service over a modern fully supported IP infrastructure without disruption to customers. The GW8000 provided the physical interface and transport protocols needed for IP access over an Ethernet connection. This allows simultaneous delivery of ATM, IP and other services to the customer premises over a single line. Activator, the Virtual Access provisioning system provisions the router and AOS and provides an OSS interface to other systems. It also assists in the migration process from the legacy network to the new network.
