Question 18/16

Question 18/16 – Signal processing network functions and equipment

(Merger of Questions 16/16 and 18/16)


This Question deals with Signal Processing Network Equipment (SPNE) including network-based speech enhancement devices such as electrical network echo control, acoustic network echo control, automatic level control devices, and voice  enhancement devices  It also deals with the implementation and interaction aspects of signal processing network equipment/terminals for transporting voice and voiceband traffic in networks.

With the increased popularity of packet-based networks using Internet Protocol (IP), more and more speech traffic is expected to be carried over these transport networks. Therefore, it will also be observed a significant amount of voice and voiceband data traffic going through signal processing network equipment , such as gateways,  circuit multiplication equipment and standalone network speech enhancement devices that interconnect the GSTN and packet networks as well as interconnect different packet networks. For this reason, there is a need to ensure a high quality of service for voice and voiceband data carried in part or wholly via IP networks.
