Node eCNS300

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.

Highly-integrated GSM-R core network solution sets the stage for efficiently upgrading to eLTE broadband

  • Three NEs integrated into one subrack reduce equipment costs and equipment room footprint.
  • 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, thus decreasing network complexity and improving reliability.
  • A unified maintenance interface reduces maintenance costs and improves efficiency.
