The ATS Messaging Management Manual describes the organizational framework in which ATS Messaging Management is implemented in the EUR/NAT Regions. The Manual specifies AMHS off-line Management Implementation Support Functions (AMF-I) and AMHS off-line Management Operations Functions (AMF-O) that are implemented in the ATS Messaging Management Centre.
AMF-I functions and AMF-O functions are intended for two different user categories: the goal of AMF-I functions is mainly to provide support to States that are in the process of implementing AMHS, and do not yet have AMHS in operational use. AMF-O functions are primarily directed to Co-operating COM Centres (CCCs), most of them being already involved in CIDIN Management, that have AMHS in operational use, in order to help managing the Regional transition from AFTN/CIDIN to AMHS.
The key functions of the AMC are address management and routing management. Address management is of utmost importance for efficient AMHS operation. It enables to coordinate the modification and distribution of AMHS addresses, as well as the synchronisation of address changes in the AMHS network, in the ATS Message User Agents and AFTN/AMHS Gateways. With routing management, AFTN, CIDIN and AMHS routing tables are defined consistently for the seamless operation of the network, and they are distributed to all COM Centres in the Region.
The network inventory, network planning, routing management and support functions existed for AFTN and CIDIN network technologies as part of CIDIN Management. These functions were complemented with AMHS-related information, to become part of the AMC so as to equally cover AMHS, CIDIN and AFTN. Other functions were developed to provide comprehensive AMHS Management, such as user capabilities management or statistics.
The AMF-O functions are performed in accordance with operational procedures which enable changes in the COM Centres to be coordinated and synchronised, taking place on AIRAC dates. The procedures are based on the organisational of each AIRAC cycle in five AMC operational phases.
The AMC has emerged as a natural focal point for distribution of information about matters not only related to network operation, but also to network implementation, particularly with regard to AMHS which is beginning to be deployed. The AMC therefore also includes AMHS off-line management implementation support functions, to provide States that are in the process of implementing AMHS with a set of guidance and implementation co-ordination functions.
