scope:
This standard defines the Feature Key Management signalling protocol for the purpose of supplementary service control at an interface at the S reference point between a Terminal Equipment (TE) and a Private Telecommunication Network (PTN). A PTN consists of one or more interconnected Private Telecommunication Network Exchanges (PTNXa), and therefore an interface at the S reference point is actually between a TE and a PTNX. The S reference point is defined in Standard ECMA-133.
