Foreword
This European Telecommunication Standard (ETS) has been produced by the European Computer Manufacturers
Association (ECMA) on behalf of its members and those of the European Telecommunications Standards Institute
(ETSI).
This ETS is one of a series of standards defining services and signalling protocols applicable to Private
Telecommunication Networks (PTNs). The series uses the ISDN concepts as developed by CCITT and is also within
the framework of standards for open systems interconnection as defined by ISO.
This particular ETS specifies the Call Forwarding Unconditional, Call Forwarding Busy, and Call Forwarding No
Reply supplementary services.
The ETS is based upon the practical experience of ECMA member companies and the results of their active and
continuous participation in the work of ISO, CCITT, ETSI and other international and national standardisation
bodies. It represents a pragmatic and widely based consensus.
The services specified are compatible with the equivalent services specified by ETSI for public ISDNs. The ETSI
specifications (listed in annex B) are to be found in ETS 300 199, ETS 300 200 and ETS 300 201 (stage 1), and
ETS 300 203, ETS 300 204 and ETS 300 205 (stage 2). Annex A describes the relationship between this ETS and
the corresponding ETSs for the public ISDN.
This ETS was produced by ECMA using the ECMA guidelines for the production of standards and using the ECMA
stylesheet. In order to avoid undue delays in the voting process for this ETS it has been agreed that this ETS will not
be converted to the ETSI stylesheet.

1 Scope
This European Telecommunication Standard (ETS) specifies the supplementary services Call Forwarding
Unconditional (CFU), Call Forwarding Busy (CFB) and Call Forwarding No Reply (CFNR), which are
applicable to various basic services supported by Private Telecommunication Networks (PTNs). Basic
services are specified in ETS 300 171.
SS-CFU, SS-CFB and SS-CFNR are supplementary services which apply during call establishment
providing a diversion of an incoming call to another destination.
Service specifications are produced in three stages, according to the method described in ENV 41005. This
ETS contains the stage 1 and 2 specifications of the Call Forwarding supplementary services. The stage 1
specifications specify the supplementary services as seen by users of PTNs. The stage 2 specifications
identify the functional entities involved in the supplementary services and the information flows between
them.
2 Conformance
In order to conform to this ETS, a stage 3 standard shall specify signalling protocols and equipment
behaviour that are capable of being used in a PTN which supports the supplementary services specified in
this ETS. This means that, to claim conformance, a stage 3 standard is required to be adequate for the
support of those aspects of the stage 1 and stage 2 clauses which are relevant to the interface or equipment
to which the stage 3 standard applies.
The stage 1 and stage 2 clauses which a stage 3 standard for the Call Forwarding Unconditional
supplementary service is required to support are clauses 6 and 9 respectively.
The stage 1 and stage 2 clauses which a stage 3 standard for the Call Forwarding Busy supplementary
service is required to support are clauses 7 and 9 respectively.
The stage 1 and stage 2 clauses which a stage 3 standard for the Call Forwarding No Reply supplementary
service is required to support are clauses 8 and 9 respectively.
