Private Telecommunication Networks (PTN)
- Signalling at the S Reference Point - Generic Feature Key Management
Protocol for the Control of Supplementary Services (SSIG-FK)
2nd edition (June 1993)
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).
The Feature Key Management protocol operates in conjunction with
the signalling protocol specified in Standard ETS 300 192 for
circuit-switched call control. It is based on the use of the two
information elements, Feature activation and Feature indication.
While the procedures associated with feature key invocation and
indication are specified in this Standard, the allocation of actual
codes used to designate individual supplementary services is outside
the scope of this Standard.
This Standard is applicable to the user accesses of PTNs and
to Tes which are intended for connection to PTNs.
