Summary

ITU-T Recommendation Q.115.2 describes the network logic for the control of voice enhancement devices/functions (VEDs) to be deployed in the network(s). A VED is defined as certain signal processing (acoustic echo control and noise reduction) in the digital transmission path. Mobile networks, where acoustic echo and noise is a common problem, are examples of where VEDs are deployed. The signal processing network equipment for VED (SPNE:VED) is the platform that incorporates the VED. The network logic described in ITU-T Recommendation Q.115.2 avoids multiple provisioning of voice enhancement devices/functions in the same digital transmission path of a connection.
