7 ETRs are informative documents resulting from ETSI studies which are not appropriate for EuropeanTelecommunication Standard (ETS) or Interim European Telecommunication Standard (I-ETS) status. AnETR may be used to publish material which is either of an informative nature, relating to the use or theapplication of ETSs or I-ETSs, or which is immature and not yet suitable for formal adoption as an ETS oran ETR consists of 4 parts as follows:Part 1:"Overview, TECHNICAL description and radio aspects";Part 2:"Radio channels, network protocols and service performance";Part 3:"Direct Mode Operation", (DTR/TETRA-01011-3);Part 4:"Network Management".

8 IntroductionThis ETR has been produced to provide an introduction to the TETRA system for potential systempurchasers, network operators and service should be understood that, as in all standard setting activities, there is an inherent conflict between thewish to have as broad a standard as possible and at the same time wanting to have as much of that broadstandard available and implemented right from the beginning. Potential system purchasers, networkoperators and service users should make sure they influence the suppliers to have their requiredfunctionality available when they need manufacturers will use the broad flexibility provided within the standard to develop andimplement systems in various ways, and still be conforming according to the standard.

9 This broadavailability of systems, each optimized around certain features and functionalities, needs to be carefullyanalysed by a network operator and system user to find the supplier with a system suited best for 8 ETR 300-1 : May 1997 Blank pagePage 9 ETR 300-1 : May 19971 ScopeThis ETSI TECHNICAL REPORT (ETR) is written as a "Read-me-first" manual or "Getting started with TETRAV oice plus Data (V+D)". It is not intended to be a complete guide to the TETRA standards. If any conflict isfound between this ETR and the clauses in the TETRA standards then the standards take aims of this ETR are many, for example:1)to provide the reader with sufficient knowledge to engage in qualified discussions with theequipment and service suppliers;2)to expose the reader to the specific language and TECHNICAL terminology used in the TETRA standards;3)to enable the reader to understand the flexibility in system design, system network topography,system availability, various modes of operation and security features.

10 4)in the radio aspects part of this ETR, sufficiently detailed design information is given to allow linkbudget calculations to be carried out and outline radio coverage planning to be the purposes of this ETR, the following references apply:[1]ETS 300 392-1: "Radio Equipment and Systems (RES); Trans-EuropeanTrunked Radio (TETRA); Voice plus Data (V+D); Part 1: General NetworkDesign".[2]ETS 300 392-2: "Radio Equipment and Systems (RES); Trans-EuropeanTrunked Radio (TETRA); Voice plus Data (V+D); Part 2: Air Interface (AI)".[3]ETR 300-2: "Radio Equipment and Systems (RES); Trans-European TrunkedRadio (TETRA); Voice plus Data (V+D); Designers guide; Part 2: Trafficaspects".
