I am ok with either text. But since the comment was raised, it made me think that when we say asynchronous and/or bidirectional, it is a particular means of telling implementation or low level design detail. There was also a question on what should go in framework vs definitions document. At this point we are focusing on high-level description and the interface for me corresponds to a logical channel. I have tried to take care of these 2 keywords by using “on-demand”, “retrieval”, “informed”. Does this explanation work for you? Or any other suggestion?

Kiran, I don’t think the objection is valid, “bidirectional and asynchronous” defines basic characteristics and is not implementation specific. If someone thinks otherwise please instantiate your objections. Thanks!

It is a technology agnostic interface. Over this NBI, slice characteristics and other requirements can be informed to TSC and current state of a transport slice can be retrieved. - TSC Southbound Interface (SBI): is an interface between 'Transport slice controller' and network controller(s). These interfaces are technology-specific and can utilize many of the existing data models such as L2SM, L3SM, VPN, etc. TSC may request network resources or retrieval of their current state.
