Overview on work of WP1/16
Question 14/16
Motivation: This Question brings together all the aspects of voice
band dial up access and facsimile transmission.
Workprogamm
Revision 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 15/16
Motivation: 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.
Workprogamm
Draft 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

Overview on work of WP1/16
Question 16/16
Motivation: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.
Workprogamm
Revision of G.168: Digital network echo cancellers including
embedded echo cancellers; G.160: Voice Enhancement Devices;
G.169: Automatic level control devices
Question 18/16
Motivation: 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.
Workprogamm
Draft 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
