Westermo gateway helps provide resilient network solutions for rail networks
Westermo are delighted to announce the introduction of Microlok® II gateway functionality to its range of Lynx Ethernet device serving switches and Wolverine Ethernet extenders. This functionality allows rail operators and system integrators to implement cost savings on interlocking and signalling projects as well as helping provide additional resilience to networks.
Microlok® II is a protocol developed by AnsaldoSTS specifically used within rail interlocking solutions. The Westermo gateway converts data from the native serial format to a UDP (user datagram protocol) packet that can then be transmitted alongside other data on a trackside Ethernet network. Westermo Lynx and Wolverine also provide the networking infrastructure capability allowing the use of gigabit fibre optic inter-connections and also the ability to use existing twisted pair or telecoms cables as the data path.
Resilient layer 2 and layer 3 protocols like RSTP, FRNT, LACP and OSPF allow highly reliable backbone networks to be created, bringing layer 3 routing protocols to the edge of the network. Built in firewall functionality also allows security to be implemented down to individual port level to ensure both accidental and deliberate security breaches are prevented.
Functionality is provided to allow up to 64 Microlok® address translations to be made and monitored. Legacy key-on/key-off support is provided as well as a unique hot/standby configuration to provide a resilient channel for hot standby controllers.
For the kinds of installation where Microlok® is used product reliability is critical to ensure maintenance costs are minimised and trains are not delayed. To provide the best solutions Westermo design all these products to have MTBF figures in excess of 500,000 hours (MIL-HDBK-217F (Gb) 25°C).
Operation at the trackside can be tough on Ethernet switches, but the Lynx and Wolverine are designed for that environment. The products will cold start at -40°C and operate over a long life time at 70°C without the need for cooling holes or fans. EMC levels trackside can be harsh and hence these products are tested and certified to meet the EN50121-4 and IEC 62236-4 standards.

About this company:
Westermo was established in 1975. The head office is located 150 km (93.2 miles) southwest of Stockholm in Sweden. Over the past three decades Westermo has grown with subsidiaries being established in Sweden, UK, Germany, France, Singapore, North America, Taiwan and sales partners appointed in over 35 Countries worldwide.
The first Westermo data communications product was an RS-232 line driver called the KM-1 that allowed data to be transmitted over great distances using twisted pair cables. Today we still sell a product, the MA-12, that is plug compatible with this device.
In the 1990s Westermo created the world’s first industrial DIN rail mount telephone modem the TD-22 pioneering remote access solutions for industrial devices like PLCs and HMIs.
In 2008 Westermo was acquired by The Bejier Electronics Corporation based in Malmo Sweden. Westermo now forms part of the Beijer Industrial Data Communications division.
