ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 2 INDUSTRY GROUP Version Management - Drivers for standardisation - YESTERDAY Legacy Rail comm. systems Custom specific development One shot solution Interoperability ends at border Loss of expertise over lifecycle Reduced Maintainability over lifecycle (ops and hardware) TODAY GSM-R systems Interoperability Interchange ability Competitive product supply New rail features globally New wireless features, GPRS.. Maintainability Economy of scale Compliance to latest EC directives, TSI’s

ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 3 INDUSTRY GROUP Benefits of standards evolution and diversified networks GSM-R networks making use of basic GSM components Voice Mail SMS GPRS SIM OTA EIRENE refers to a set of: 53 normative GSM specifications (ETSI) 13 normative Rail specifications Standards evolution and diversified networks are welcome Diversified set of suppliers Railways buy of the shelf products to accomplish their GSM-R plus demands Suppliers are GSM but not GSM-R centric Evolution of standards today Over 400 rail specific CRs received from Railways Multitude of ETSI GSM CR’s processed Version management ensuring system integrity is required

ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 9 INDUSTRY GROUP Best Practises - 3GPP & GCF Defined minimum set of rules to certify compliancy On minimum diversified systems Full type approval (FTA) covers compliancy fatalities only Do not cover GSM-R specifics Valid for t=T0 only No regression testing after t0 Non compliancy triggered through customer complaints non compliancy usually resolved with hardware upgrade Third Generation Partnership Project (3GPP) & Global Certification Forum (GCF)
