  1. ITU-T Workshop on “Interactions of Voiceband Signal Processing Functions and their End-to-End Coordination” (Germantown, Maryland, USA, 21 April 2010) SG16/WP1 Network signal processing and voiceband terminals  Harald Kullmann

  2. Overview of WP1/16 • Question 14/16 – Voiceband modems and facsimile terminals and protocols: specification, performance evaluation and interworking with NGNRapporteur: Keith CHU, Teridian Semiconductor Corporation • Question 15/16 – Voice gateway signal processing functions and circuit multiplication equipment / systemsRapporteur: Dominic HO, Ericsson • Question 16/16 – Speech enhancement functions in signal processing network equipment (SPNE)Rapporteur: Bob REEVES, BT • Question 18/16 – Interaction aspects of signal processing network equipment (SPNE)Rapporteur: Harald KULLMANN, Deutsche Telekom

  3. Overview on work of WP1/16 Question 14/16Motivation: This Question brings together all the aspects of voice band dial up access and facsimile transmission.WorkprogammRevision of T.38: Procedures for real-time Group 3 facsimile communication over IP networks; V.150.1:Modem-over-IP networks; Procedures for the end-to-end connection of V-series DCEs; V.152: Procedures for supporting voice-band data over IP networks Question 15/16Motivation: This Question deals with the specification of voice gateway equipment. Circuit switched systems and equipment have traditionally transported voice and voiceband traffic in international networks. WorkprogammDraft new Rec. G.IP2IP: Signal processing functionality and performance of an IP-to-IP voice gateway optimised for the transport of voice and voiceband data; Revision of G.799.1: Functionality and interface specifications for GSTN transport network equipment for Interconnecting GSTN and IP Networks

  4. Overview on work of WP1/16 Question 16/16Motivation:This Question deals with network-based speech enhancement devices, including electrical network echo control, acoustic network echo control, automatic level control devices, and speech enhancement devices. WorkprogammRevision of G.168: Digital network echo cancellers including embedded echo cancellers; G.160: Voice Enhancement Devices; G.169: Automatic level control devices Question 18/16Motivation: This Question deals a) the logic and protocol requirements needed for the control and coordination of signal processing functionalities in the networks and terminals; b) with the study of interaction of SPNE, between different SPNE, between SPNE and terminals, and between SPNE and transmission systems; and c) with the consistency of Recommendations developed by Questions 15 and 16/16 in the area of SPNE.WorkprogammDraft new Rec. G.SPNE: Information and requirements for Signal Processing Network Equipment (SPNE); Revision of G.799.2:Mechanism for dynamic coordination of signal processing functions; G.161: Interaction Aspects of SPNE
