Integrated railway telecommunications network

Railway companies today are faced with growing mobility of people and goods, increased security and safety requirements together with permanent pressure on operational expenses. This is leading to an increasing need for modernising their telecommunications infrastructure.

Essentials of this modernisation are to rationalise telecommunications infrastructure, pool services into one integrated managed network and increase automation. These measures help reduce operational costs.

Rising levels of mobility produce higher velocity and cycle rhythms on railway networks, which cause increased security requirements and increased demand for information and broadband communication services for customers. However, legacy network technologies and parallel networks are unsuitable for meeting these demands.

It is better to provide a multi-service backbone network for all services. This means lower investment outlay, simplification of operations, lower OPEX and the future-proofing for new applications and services.

With KEYMILE's flexible system design you can deliver any service in any network. KEYMILE's products offer a wide range of data, voice and IP interfaces, integrated SDH-function and service availability levels at 99.999%. This makes KEYMILE's product family the ideal choice for telecommunications networks for railways.

Combined rail telecommunication network

UMUX is a hardened multi-service access and transmission system that integrates a variety of applications and interfaces. It provides multiplexing and aggregation as well as optical transport of data in a compact network element, allowing railway companies to consolidate all their telecom requirements on a single telecommunications network made of UMUX systems simply and safely.

The services supported include E&M, traditional POTS/ISDN telephony, local battery interfaces, broadband and narrowband data connections, Ethernet, Gigabit Ethernet and VoIP applications. With its Ethernet-over-SDH functionality, UMUX combines state-of-the-art Ethernet technology with the deterministic TDM process. Services such as critical IP communication or video surveillance can be provided efficiently, economically and extremely reliably.

UMUX features power-over-Ethernet (PoE+), realizing Ethernet connections in locations without local power, making it suitable for deploying terminal devices such as video cameras, IP telephones, access control systems, wireless access nodes and wireless local networks in remote locations.

Due to its sophisticated Ethernet over SDH (EoS) functionality, UMUX was accredited by the Swiss Federal Office of Transport for use in closed transmission networks, in accordance with the safety standard EN 50129-1. The UMUX platform from KEYMILE is the only multi-service transmission system that has this accreditation in Switzerland – a leading country in railway technology and solutions.

Modular and compact access multiplexer

The XMP1-LCC is a modular, compact access multiplexer can be fitted with 2Mbit, Ethernet and SDH interface cards. STM1/STM4 (optical and electrical) or STM16 (optical) interfaces are available for SDH connection. For Ethernet data, the XMP1-LCC offers Fast Ethernet and GbE interfaces whose data is transmitted with EoS functions (Ethernet over SDH) via the SDH network.

The Ethernet packets are controlled and switched via a layer-2 switch. As a result, the XMP1-LCC is ideal as an access multiplexer in the SDH backbone. Thanks to its vast cross-connect capacity and high number interfaces, it consolidates incoming PDH and Ethernet data for forwarding to the SDH backbone network.

The XMP1-LCC belongs to the XMP1 family and supports the protection functions and operation modes of the XMP1 multi-service access multiplexer. Typical public transport and railway company applications are: E1 and Ethernet access multiplexers in the SDH backbone.

Transmission solution for telecontrol / SCADA applications

LineRunner SCADA NG is a versatile and hardened next generation multi-drop system providing an economical and reliable transmission solution of up to 11.4mbps in telecontrol and automation applications. Due to its flexible network interfaces, LineRunner SCADA NG fits into diverse network infrastructures constituted with copper cables, fibre optic cables and legacy transmission PDH/SDH networks. Data is exchanged over a network of up to 63 stations in a row.

The transmission solution for telecontrol LineRunner SCADA NG supports Ethernet and RS232 user interfaces; it's perfectly designed for supporting telecontrol and automation data, as well as transporting IP video surveillance and VoIP telephony traffic flows. Thanks to its small size and flexible powering concept, LineRunner SCADA NG fits into almost every location.
