3Overview 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.WorkprogammRe
vision of T.38 Procedures for real-time Group 3
facsimile communication over IP networks
V.150.1Modem-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.

- Question 16/16 MotivationThis 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.

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

6 ITU-T Workshop on Interactions of Voiceband
Signal Processing Functions and their End-to-End
Coordination
- ObjectivesDiscussion on topics related to
Signals Processing Functions in terminals,
networks, end-to-end coordination and
implementation aspects - TargetsThis WS aims at covering the topics
related to the identification of follow-up
actions to application areas and implementation
aspects and the verification of existing and
in-progress standards and the identification of
the need for filling gaps.
