NEMA NTCIP 1210:2013

NTCIP 1210 v01 defines requirements related to the Information Level communications interface between a management station and a signal system master (SSM). This is achieved through the presentation of user needs for such an interface in Section 2 with detailed functional requirements presented in Section 3. NTCIP 1210 v01 includes references to the communications interface between the SSM and a Signal System Local (SSL). However, the standardized definition of that interface is provided in other standards, such as NTCIP 1202 v02. NTCIP 1210 v01 only addresses a subset of agency specification (procurement) requirements. NTCIP 1210 v01 does not address requirements related to the accuracy of readings, hardware components, mounting details, etc. NTCIP 1210 v01 standardizes the communications interface by identifying the various operational needs of users and subsequently identifying the requirements that supported each need. A summary of the conformance requirements are provided in Annex A through a Requirements Traceability Matrix (RTM).
