# Interface Architecture

Instructions: Describe any interfaces that exist with external systems that are not within the scope of the system being designed, regardless whether the other systems are managed by you or another entity.

  

Describe the electronic interface(s) between the system being designed and each of the other systems and/or subsystem(s), emphasizing the point of view of the system being designed. 

If there are more than one or two external systems, or if the interfaces are not simplistic, one or more separate Interface Control Documents (ICDs) should be prepared and referenced here.

## Interface Architecture

### Instructions: 

*   Describe the interface(s) between the system being developed and other systems (e.g., batch transfers, queries, etc.), indicating the location of the interfacing system. 
    
*   Include the interface architecture(s) being implemented (e.g., wide area networks, gateways, etc.) and the interfacing mechanisms (e.g., MQ, Gentran, etc.) 
    
*   If remote connectivity is required, identify the method of access. 
    
*   Provide a diagram depicting the communications path(s) between this system and each of the other systems, which should map to the context diagram(s) provided in the Section for System Overview. 
    
*   The graphical representation should depict the connectivity between systems, showing the direction of data flow. Use subsections or a separate ICD(s) to address each interface independently.
