The present document provides the Implementation Conformance Statement (PICS) proforma for the signalling
application for the mobility management service on the alpha interface for the pan-European Integrated Services Digital
Network (ISDN) as provided by European public telecommunication operators at the T reference point or coincident S
and T reference point (as defined in ITU-T Recommendation I.411 [9]) 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 [8]).
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the
signalling application for the mobility management service on the alpha interface as specified in EN 301 144-1 [5] in
compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [7].
The supplier of a protocol implementation which is claimed to conform to EN 301 144-1 [5] is required to complete a
copy of the PICS proforma provided in annex A of the present document and is required to provide the information
