EMS stands for "Entity Management System". It manages one Network Element or similar type of network element but NMS is one level ahead in the hierarchy and it manages the EMS . When data traffic need to pass from one network element to another network element then it leverages the interface that is exposed towards NMS.

In short, one NMS may contains various EMS.
