ITU-T Q.55
Signalling between signal processing network equipments (SPNE) and international switching centres (ISC)More info
This ITU-T Recommendation describes a signalling interface, procedures, and protocol required between an International Switching Centre (ISC) and Signal Processing Network Equipment (SPNE). This signalling interface provides for the call by call control of an SPNE in real time to ensure an appropriate signal enhancement capability such as echo control. The framework of this signalling interface allows for growth for the control of potential further SPNE types.
