This single-frame core network solution reduces the costs of GSM-R communications while it sets the stage for transforming railway communications to eLTE broadband. The eCNS300 does this by customizing and integrating three Network Elements (NEs) into a single cabinet.
The solution is built on the Advanced Telecom Computing Architecture (ATCA) hardware platform, which supports upgrades to eLTE. GSM-R users can replace a hardware module and upgrade the software to implement eLTE without replacing the entire system.
Three NEs integrated into one subrack reduce equipment costs and equipment room footprints.
Rack space is reserved for packet-switched equipment that will support the evolution to eLTE.
A simplified network structure reduces the number of intermediate nodes between core network NEs, which decreases network complexity and improves reliability.
