The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the
"Narrowband Multi-service Delivery System (NMDS)" defined in EN 301 141-1 [3] in compliance with the relevant
requirements, and in accordance with the relevant guidance given in ISO/IEC 9646-7 [5] and ETS 300 406 [2].
It allows either the network operator to formulate the requirements for an NMDS implemented in an Access
Network (AN) or a Service Node (SN), or to decide whether an implementation meets these requirements. It details in
tabular form the implementation options, i.e. the optional functions additional to those that are mandatory to implement.
