This Recommendation describes a signalling interface between an International Switching Centre (ISC) and an external, stand-alone Echo Control Device (Echo Suppressor, Echo Canceller), referred to as an ECD.

This interface is supported in E1- and T1-networks.

The signalling interface defined in this Recommendation assumes a fixed relationship between the circuits of the ISC and the external ECD.

While this Recommendation is intended for use on international networks, the information defined here may be used within national networks.
