The information pertaining to the

No guarantee can be given as to the existence of other IPRs not referenced in SR O00 314 (or the updates on the ETS
31、I Web server) which are, or may be, or may become, essential to the present document. Foreword This ETSI Standard (ES) has been produced by ETSI Project Analogue Terminals and Access (ATA). EN 301 071-1 version 1.1.1 was previously sent on Public Enquiry PE 9746. As a result of comments received dur
32、ing Public Enquiry it was agreed within the Technical Body to change the deliverable type to an ETSI Standard. A Technical Specification; TS 101 071 has also been published by ETSI. EN 301 071-2 has been abandoned due to lack of support. I nt roduct ion The Server Display and Script Services protoco
33、l (SDSS) is the European equivalent of the Analogue Display Services Interface (ADSI) protocol. The SDSS protocol provides bi-directional data communication in an analogue environment between a TE and a Server. The Server may be external to the network or integral with the network. The protocol uses
34、 FRquency Shift Keying (FSK) signalling for downstream transmission of data and uses DTMF signalling for upstream transmission of data. There are many potential physical implementations of the TE and its user interfaces and it is not the intention of the present document to restrict the physical imp
35、lementation in any way. However, in order that any SDSS TE may interwork correctly with an SDSS Server, it is essential that all SDSS TE have some common features. This is provided by means of the concept of an abstract TE which is the functionality the Server assumes the TE to have in order to inte
36、rwork correctly and comprises a set of logical components that all physical SDSS TE provide. The abstract TE supports two applications: a) Server Display Control applications (interactive ADSI session with remote Server). b) Feature Download applications (advanced call management service ADSI script
37、 originating from the network - no Server interaction during session). ETSI 8 ES 201 071 V1.1.2 (1998-10) 1 Scope The present document specifies the requirements necessary to support Server Display and Script Services (SDSS) screenphone services. The requirements are intended to ensure correct inter
38、working between a TE and a SDSS Server using the core protocol defined in Bellcore ADSI specifications SR-INS-002461 5, TR-NWT-O1273 6, associated Bulletins 8 and 9 and Revision 1 13, but modified and extended to include European network signalling events and physical access requirements.
