Page 11ETS 300 347-1: September 1994ForewordThis European Telecommunication Standard (ETS) has been produced by the Signalling Protocols andSwitching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS is part 1 of a multi-part standard covering the V5.2 interface specification as described below:Part 1:"V5.2 interface specification";Part 2:"Protocol Implementation Conformance Statement (PICS) proforma";Part 3:"Test Suite Structure and Test Purposes (TSS&TP) for the network layer, Access Network(AN) side";Part 4:"Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing(PIXIT) proforma for the network layer, AN side";Part 5:"TSS&TP for the network layer, Local Exchange (LE) side";Part 6:"ATS and partial PIXIT proforma for the network layer, LE side";Part 7:"TSS&TP for the data link layer";Part 8:"ATS and partial PIXIT proforma for the data link layer";Part 9:"Test specification for the physical layer".Transposition datesDate of latest announcement of this ETS (doa):31 December 1994Date of latest publication of new National Standardor endorsement of this ETS (dop/e):30 June 1995Date of withdrawal of any conflicting National Standard (dow):30 June 1995IntroductionGeneralThe work on a new V interface concept was initiated by a request from the ETSI Technical Assembly (TA)to Technical Committee (TC) Network Aspects (NA), in particular Sub-Technical Committee (STC) NA4 toconsider, in co-operation with other STCs involved, possible new structures and interfaces for theconnection of new access arrangements to local exchanges. After two meetings (in January and May1991) the work was terminated with some guidelines for further consideration.The work was taken over by a Special Experts Group, set up by TC SPS, working under STC SPS3, withexperts from several STCs, e.g. SPS5, Transmission and Multiplexing (TM) 3 and NA4. This was to avoida split of the difficult task to several STCs requiring intensive co-operation and possibly may have causedsignificant delay of the standardization work.TC SPS identified in the terms of reference two interface concepts, one based on a static multiplexerprinciple, now called the V5.1 interface, and the other based on a dynamic, concentrator type, principle,now called the V5.2 interface.SIST ETS 300 347-1:1997
Page 12ETS 300 347-1: September 1994This V5.2 interface standard, forming part of a number of standards of the V5 interface concept, has beendeveloped by the Special Experts Group mentioned above. Due to the importance of this new V5 conceptand the urgency identified by SPS, the Special Experts Group met almost every month over a time periodof 17 months to fulfil this task.Other STCs involved have been informed about the decisions made and the progress of work by regulardistribution of the meeting reports and any other material to the STC chairman and other involved people.SPS3 and SPS5 were
