The present document provides the ICS proforma for the signalling application for the mobility management service for
the phase 1 of Call Forwarding on Not Reachable (CFNRc) supplementary service for the pan-European Integrated

or coincident S and T reference point (as defined in ITU-T Recommendation I.411 [2]) by means of the Digital
Subscriber Signalling System No. one (DSS1) protocol. Stage three identifies the protocol procedures and switching
functions needed to support a telecommunications service (see CCITT Recommendation I.130 [1]).
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the signalling
application for the mobility management service for the phase 1 of CFNRc supplementary service specified in
EN 302 094-1 [8] in compliance with the relevant requirements and in accordance with the relevant guidance given in
ISO/IEC 9646-7 [10].
The supplier of a protocol implementation which is claimed to conform to EN 302 094-1 [8] is required to complete a
