NBN begins second Cell Access trial

National broadband company continues to develop product to allow mobile carriers to tap into their fibre network

The company responsible for building the National Broadband Network, nbn, has released details of its proposed Cell Site Access Service (CSAS) — designed to allow mobile carriers to connect their mobile towers using NBN infrastructure.

This comes as nbn finishes their first round of trials with their customers which started at the end of 2013 and continued through till June this year. However, given the duration of this second trial which is not expected to end till July 2017, it appears that initial plans to have a cell site access product available to customers by the end of the year will be pushed back further.

Former CEO of Vodafone Australia and now NBN-CEO was once a strong advocate for the introduction of the backhaul service. However, the company recently signed a deal with TPG telecom to build out its fibre network to all of Vodafone’s cell sites.

According to the updated testing agreement, nbn will trial the CSAS at a “mobile complex” in Beaudesert, Queensland where the company has begun rolling out its fibre to the node and fixed wireless network. As part of the service, the carrier will receive a network extension quote equivalent to one from the company’s “Technology Choice Program” to extend the fibre network (FTTP) to the designated cell site.

During the trial, the company will not charge the participating carrier for this network extension or any associated costs with this service including the Access Virtual Circuit (AVC), User Network Interface (UNI), Connectivity Virtual Circuit (CVC) and Network-Network Interface (NNI) — however, it says it will intend to do so once the trial is completed.

The test agreement also makes mention of potentially co-locating the cell tower with towers used by NBN’s Fixed Wireless service as part of a facilities access agreement with the access seeker. The NBN company will also determine the network traffic class used during the trial.

The CSAS trial is expect to continue until 1st July 2017.
