Access and Terminals (AT); Analogue access to the Public Switched Telephone Network (PSTN); Protocol over the local loop for display and related services; Terminal equipment requirements; Part 4: Test Suite Structure and Test Purposes (TSS&TP); On-Hook and Off-Hook

Published by: 2002-11-01 / 2002-11-01 / 49 pages
The present document specifies the Test Suite Structure and Test Purposes (TSS&TP) for both the On-Hook and the
Off-Hook Data Transmission over the PSTN Access for Terminal Equipment (TE).

In order to stay aligned with the structure of the base standard, the present document specifies test purposes for FSK
signalling while the DTMF test purposes are included in the annex A.

The present document does not cover the combination of services.

ES 200 778-5 [6] specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for
Testing (PIXIT) proforma based on the present document.

Open Service Access (OSA); Application Programming Interface (API); Part 5: User Interaction SCF (Parlay 3)

Published by: 2006-12-01 / 2006-12-01
The present document is part 5 of the Stage 3 specification for an Application Programming Interface (API) for Open Service Access (OSA).

The OSA specifications define an architecture that enables application developers to make use of network functionality through an open standardised interface, i.e. the OSA APIs.

The present document specifies the User Interaction (UI) Service Capability Feature (SCF) aspects of the interface. All aspects of the User Interaction SCF are defined here, these being:

  • Sequence Diagrams.
  • Class Diagrams.
  • Interface specification plus detailed method descriptions.
  • State Transition diagrams.
  • Data Definitions.
  • IDL Description of the interfaces.

The process by which this task is accomplished is through the use of object modelling techniques described by the Unified Modelling Language (UML).

Speech Processing, Transmission and Quality Aspects (STQ); Distributed speech recognition; Front-end feature extraction algorithm; Compression algorithms

Published by: 2003-09-01 / 2003-09-01
The present document specifies algorithms for front-end feature extraction and their transmission which form part of a
system for distributed speech recognition. The specification covers the following components:

  • the algorithm for front-end feature extraction to create Mel-Cepstrum parameters;
  • the algorithm to compress these features to provide a lower data transmission rate;
  • the formatting of these features with error protection into a bitstream for transmission;
  • the decoding of the bitstream to generate the front-end features at a receiver together with the associated
    algorithms for channel error mitigation.

The present document does not cover the “back-end” speech recognition algorithms that make use of the received DSR
front-end features.

The algorithms are defined in a mathematical form or as flow diagrams. Software implementing these algorithms
written in the “C” programming language is contained in the .ZIP file which accompanies the present document.
Conformance tests are not specified as part of the standard. The recognition performance of proprietary
implementations of the standard can be compared with those obtained using the reference “C” code on appropriate
speech databases.

It is anticipated that the DSR bitstream will be used as a payload in other higher level protocols when deployed in
specific systems supporting DSR applications. In particular, for packet data transmission, it is anticipated that the IETF
AVT RTP DSR payload definition (see bibliography) will be used to transport DSR features using the frame pair format
described in clause 6.

Access and Terminals (AT); Short Message Service (SMS) for PSTN/ISDN; Short Message Communication between a fixed network Short Message Terminal Equipment and a Short Message Service Centre

Published by: 2004-08-01 / 2004-08-01 / 90 pages
The present document deals with two different protocols to provide the Short Message Service for PSTN/ISDN using a User Based Solution (UBS). For both protocols it specifies the protocol layers used to transmit Short Message Information between Short Message Terminal Equipment connected to PSTN/ISDN and a Short Message Service Centre. It is up to the service provider to choose which protocol to use.

It does not specify the dial-in systems and the architecture of the short message service centres.

Open Service Access (OSA); Application Programming Interface (API); Part 9: Generic Messaging SCF

Published by: 2003-07-01 / 2003-07-01
The present document is part 9 of the Stage 3 specification for an Application Programming Interface (API) for Open
Service Access (OSA).

The OSA specifications define an architecture that enables application developers to make use of network functionality through an open standardised interface, i.e. the OSA APIs.

The present document specifies the Mobility Service Capability Feature (SCF) aspects of the interface. All aspects of the Mobility SCF are defined here, these being:

  • Sequence Diagrams.
  • Class Diagrams.
  • Interface specification plus detailed method descriptions.
  • State Transition diagrams.
  • Data Definitions.
  • IDL Description of the interfaces.

Speech Processing, Transmission and Quality Aspects (STQ); Harmonized Pan-European/North-American approach to loss and level planning for voice gateways to IP based networks

Published by: 2007-06-01 / 2007-06-01
The purpose of the present document is the harmonization of loss and level planning between the Pan-European and the
North American regions, with a global view and the intent that the present document may be subject to adoption by
other regions, in future. An equivalent standard has been published by the North American Telecommunications
Industries Association (ANSI/TIA-912-B [1]).
